Create a project
Enter a working title to create a separate workspace for a work. In the first consultation, describe what you want to write and the ideas you have using suggested replies, text, or voice.
The Web creation form with a working title and optional manuscript and reference import.
Create with a title alone, or choose existing files to import.
Import an existing work
On Web and iOS, choose existing manuscripts and setting notes when creating a work and organize them into manuscripts and references. Select multiple files or a ZIP archive. Web also supports folder selection in compatible browsers; on iOS, select a compressed copy of the folder. Formats include Word, Excel, PDF, text, and JSON. Limits are 25 MB per file, 100 MB total, and 500 files. We reserve 100 AI credits at the start and use them on completion. Your storage plan's limits also apply.

Web UI example. Review selected files, upload limits, and AI credit conditions before starting.
Import progress and cancellation
On Web and iOS, view the current task, time since its last update, and whether a decision is needed. You can cancel an import. Imports that end in failure, cancellation, or expiry before completion release the reserved AI credits.
Web UI example. The current import task, reserved credits, and cancel and refresh controls.
Web UI example. Check the import state and time since the last confirmed task update.
Review manuscript and reference choices
When different draft versions or organization choices need your decision, use the Web or iOS review screen to choose what to save. Inspect original files and add details. You can keep an alternative draft as reference material.
Web UI example. Choose which of two drafts becomes the manuscript and which remains in references.
Web UI example. Review original files and choose what to save. Both versions are kept in this example.
Resume an import
After files finish uploading, processing continues even if you close the Web screen or iOS app. Within the retention period, open the same import from the project list on Web or iOS with the same account to make decisions or check results. Resuming the same import uses no additional AI credits. If you quit the iOS app, select any files that have not been uploaded again.
Web UI example. A link from the project list to an import awaiting an author decision.
Web UI example. Open an ongoing import again from the project list.
Import results and original files
On Web and iOS, check what was saved as manuscripts and references, alongside unreadable or excluded items. Original files are available for seven days from the start of the import: download them on Web, or open them with the device's sharing feature on iOS. Cancelling ends access to original files. Saved manuscripts and references remain in the work afterwards. If you choose to complete with only part of the content, the completed import still uses 100 AI credits.
Web UI example. The completed import, destination for each file, and original-file expiry.
Web UI example. Review the results and open the work. Original files remain available during the retention period.
Starter sample project
After registration, open a sample project containing a manuscript, reference material, and AI conversations. Use its contents to check the screens and features.
Project list
View each work's title, manuscript count, thread count, and last update. Select a work to open its writing workspace.
Rename or delete a work
Rename a work from the project list. Before deleting one, review the selected work in a confirmation dialog.
Japanese and English works
Create works in Japanese or English. AI responses, character or word counts, search, voice features, and file exports follow the work's language.
Works shared across Web and mobile
Sign in with the same account to open the same manuscripts, references, and conversations on Web and mobile. Your plan and AI credits are also shared.

Dashboard and writing progress

View writing charts, a calendar, writing goals, and earned badges.

8

Writing dashboard
On Web and iOS, view recorded saving days, the longest streak within the selected period, and your current work count. Web also shows the period’s net body change. Body length and goals for up to five recently updated works are current values, independent of that period. Starter samples are excluded. Available on Free; viewing does not use AI credits.
Fictional Web period summary showing net body changes, recorded saving days, the longest streak in the period, and the separate current work count.
Fictional Web period summary showing net body changes, recorded saving days, the longest streak in the period, and the separate current work count.
Current goals for three fictional works: a Japanese work in progress, an English work above its goal, and a work without a goal. These values are independent of the historical period.
Current goals for three fictional works: a Japanese work in progress, an English work above its goal, and a work without a goal. These values are independent of the historical period.
Manuscript length chart
On Web and iOS, view daily net body changes from recorded saving activity and the period’s cumulative change in charts and numerical tables. Web uses daily bars and a cumulative line; iOS uses bars for both. Reductions stay negative; these values are neither total text written that day nor full manuscript length. Switch between Japanese characters and English words without adding them together. Internal AI edits are excluded; dates before tracking began remain untracked.
Web charts for fictional daily net manuscript changes and the selected-period cumulative change, including negative changes and untracked dates.
Web charts for fictional daily net manuscript changes and the selected-period cumulative change, including negative changes and untracked dates.
Writing activity date range
Web and iOS start with the last seven days. Choose 30, 90, or 365 days; today; this week; this month; or inclusive custom dates within the last 365 days including today. Saving activity is retained for 365 days. Dates follow your device’s time zone, falling back to UTC if unavailable. Deleting a work deletes its activity records.
Set inclusive start and end dates and switch between Japanese characters and English words in the Web app, using fictional saving activity.

Writing calendar
On Web and iOS, distinguish dates with recorded saves, no saves, and no tracking, then select a date for its save count. Web also shows separate net body changes for Japanese and English works. Save counts are not manuscript length or a quality score, and history before tracking began is not inferred from work update times.
Select a fictional saving date in the Web calendar to view save counts and separate changes in Japanese characters and English words.

Browse earned badges and filter by account or project scope.
Badge celebrations and display settings
The web and iOS apps celebrate newly earned badges. Celebrations wait while you are typing or using voice controls, and group badges earned together. Each celebration appears once. The display preference applies to your account; turning it off does not stop you earning badges.
The Web badge celebration with continue, sound, and future-display controls.
Each new achievement is celebrated once. Sound and celebration display have separate controls.
Badge celebration sound
Turn sound on or off during a celebration or in settings in the web app and iOS 1.2.4 or later. Sound starts enabled, and turning it off stops any sound playing. Your choice is saved per browser or device and does not sync to other devices. Browser playback restrictions may prevent sound in the web app.
The Web badge settings card with celebration display and sound controls.
Celebration display applies to your account; sound is saved in this browser.
AI credits for new badges
On any plan, including Free, newly achieved badge types grant 10, 20, 30, 50, or 100 AI credits once per account and type. Credits expire 90 days after the grant. Earning the same type in another work gives no duplicate reward; past achievements added during an existing account's first check give no reward. Turning celebrations or sound off does not change eligibility.

This fictional example earned 100 AI credits. The amount depends on the badge type.

Writing workspace

Arrange your workspace, change project settings, save and recover drafts, and undo work changes.

Writing workspace
On wide Web screens, view AI consultation, the manuscript outline, and the prose editor side by side. On narrow screens, switch between chat, manuscript, and references, and open the outline or reference list when needed.
AI consultation on the left, with the chapter outline and manuscript editor on the right.
AI consultation on the left, with the chapter outline and manuscript editor on the right.
Manuscript, references, and project settings
Switch between the manuscript, reference material, and project settings without closing the work. The consultation area remains available for the same work.
Resizable work areas
On wide Web screens, move the boundaries between the consultation area, manuscript or reference list, and editor to adjust their widths. The same browser remembers these widths, with one list width shared by the manuscript and references.
Open AI work results
Open manuscripts or references created or updated by AI from the result display and check what was saved.
Save manuscripts and reference material
On Web, including Free, manuscript and text or structured-reference edits save automatically after about seven seconds without input or when you leave the editor. Continuous input is grouped at intervals of up to 30 seconds. Check Saving, Saved, or a failure with Retry. Changes to multiple manuscript blocks save together at one boundary. On iOS, use Save to apply edits to the work. Device drafts and saved work are separate. Updating the AI search index after a manuscript save may use AI credits. A failed index update keeps the saved manuscript.
Recover unsaved input and review conflicts
Web and iOS retain unsaved manuscript and reference input on the device, separately by account, work, and edited item. On Web, review retained input after reloading the same tab. If another screen changed the work, load the latest content, then restore your input to apply it again or discard it. Copy retained input for deleted items. iOS loads device drafts; choose the latest version or the device draft when they conflict, then save to the work. Drafts do not sync to other devices. Web recovery is not guaranteed after closing the tab or clearing browser storage.

Input stays retained while you load the current work and choose whether to apply it again.
The Web choice to restore retained input or discard it.
Restore my input reapplies the draft to the current work. Save responses are illustrative fixture data.
Project-wide undo and redo
On Web and iOS, including Free, undo or redo saved changes to the manuscript and its structure, reference material, work title, and writing policy. Revert creative changes saved during one AI request together. Conversation, subscriptions, and used AI credits are not rewound. These controls are unavailable during AI execution; on iOS, save unsaved device drafts to the work first. A new edit after Undo removes the usual Redo path. History from its starting point is retained while the work exists and is subject to deletion when the work or account is fully deleted.
The published Web header with project-wide Undo, Redo, and Saved status.
Actual Web UI with fictional save and history responses; not a production persistence result.
Writing policy
Save up to 4,000 characters of instructions for one work, such as style and notation. Use project settings on Web or Manage in the iOS project list. Web stores the policy as editable reference material that the AI can consult. Clear the field to remove its instructions. Saved changes apply to subsequent AI responses and are shared across your devices. Editing the setting itself uses no AI credits.

AI consultation

Discuss your work using manuscripts, references, and creative writing knowledge. Create and edit manuscripts and references, generate images, and listen to responses.

25

AI chat
Discuss your work in text and receive ideas, organized setting notes, outlines, and draft passages. AI responses use AI credits.
A sample answer for a fictional work with suggested replies, copy, read-aloud, and retry controls.
Choose a suggestion to send its text. The latest eligible answer also has a retry control below it.
Voice input and transcription
Dictate a title or consultation message on Web and iOS. On Web, also dictate into manuscripts, text fields in references, project settings, and your account custom prompt. Web's shared voice input inserts at the selected position; use the field's usual saving controls. Recording requires microphone permission. Transcription sends audio to external AI and uses AI credits on plans including Free. The language context follows the project's writing language inside a project, or your display language elsewhere (Japanese or English).
Published Web project settings while recording into the project title, with stop and discard controls.
Web example of dictating a project title. The microphone input is sample data used to illustrate the recording controls.
Retry recordings and review recognized text
A failed transcription keeps the recording on the device, separately for each account, so you can retry or delete it. In Web's shared voice input, changing the field or its content during recognition keeps the result for you to choose where to insert it or copy it. Undo the insertion if you have not edited the field afterward. Uninserted recognized text stays only in the open page and is lost when the browser closes. Successfully transcribed recordings are deleted.
The edited project title is kept while recognized text remains available for insertion or copying in the Web UI.
Review the result and choose where to insert it while preserving edits made during recognition. The transcription response is fictional illustration data.
Thread management
Create, rename, switch, and delete threads for different topics or purposes, such as characters, scenes, and settings.
AI model selection
Save a default AI model on Web or iOS and share it across your account. Leave it unset to use Plan recommendation. Free offers Light; Mini, Light, and Standard plans offer Light and Standard models; Pro also offers High-performance. A model chosen in the chat composer is used for that response without changing your saved default. If a plan change makes the saved model unavailable, the current plan recommendation is used. Selecting a model uses no AI credits; generating a response does.
The model menu opened from the Web chat composer, with High-performance selected.
An example of the three choices available on Pro. Selecting one for a consultation does not change the saved default model.
AI personality settings
Choose Standard, Serious, Cheerful, or Literary on Web or iOS to set the AI's approach and response tone. The setting is shared across your account and applies to subsequent responses after saving. It does not change established facts about your work or available features. Editing the setting itself uses no AI credits.
AI instructions shared across your works
Save up to 4,000 characters of style or response preferences as a user custom prompt in Web or iOS AI settings. Changes apply to subsequent AI responses after Save on Web or successful autosave on iOS. They are shared across your account, preserve line breaks and spaces, and can be cleared with an empty field. When instructions conflict, your current request takes priority, followed by the work's writing policy and then these shared preferences. They do not override safety rules, established work facts, or available features. Editing the setting itself uses no AI credits.
Web AI preferences with personality, default model, and instructions shared across works.
An example with Literary, the Standard model, and fictional shared instructions. Use Save on Web to apply changes.
Suggested replies
On Web and iOS, if the latest AI answer has suggestions, selecting one immediately sends its text as your next consultation. The new AI response uses AI credits. You can also type your own message. Send the next consultation after the current AI operation finishes.
Stop a response
On Web and iOS, request a stop during an AI operation. A stopping indicator leads to the confirmed outcome: stopped, completed normally, or failed. Changes to manuscripts, references, or other content saved before the stop remain.
Web's stopping indicator above a draft of the next consultation.
Draft the next message while waiting for the stop to finish. The stopping state is a sample used for illustration.
Draft during an AI response
While the AI responds, type the next message, record voice input, or select the next AI model. A recording stopped during a response stays on the device and is transcribed after that response finishes. Send the next consultation after the current operation finishes.
Image generation
On Web and iOS, explicitly request an image concept for a character, location, cover, or other subject. Generate up to one image per request and view it with explanatory text in the conversation. Generation uses AI credits and requires a sufficient balance. Images are proposals for discussion and are not automatically adopted into the work's established facts or reference materials.
A Web conversation image concept with a description and controls to adjust or save it.
The image content is an owned sample used for illustration. Review a proposal before adjusting or saving it.
Diagrams in conversations
On Web and iOS, view character relationships, event sequences, and hierarchies as diagrams. When helpful, the AI combines prose and diagrams in the finalized answer. If a diagram cannot be displayed, you can still read the explanation and the diagram's source text.
A fictional Web answer explaining three investigation steps with prose and a diagram.
Read the prose and diagram together. Show diagram source also opens the original description.
Adjust and save images
On Web and iOS, select a conversation image and draft a revision request. Selection does not send the message; a revised image keeps the original intact. Generation and revision use AI credits. Confirm a name and destination in the same work before saving your chosen image as reference material and opening it. Saving is subject to the reference storage and file limits of your current plan. Conversation images and saved references are retained separately. Deleting the conversation keeps saved references; deleting a saved reference keeps the conversation image. Deleting the work removes both.
The Web confirmation form for a file name and destination before saving an image as reference material.
Choose a destination in the same work and confirm the name before saving. The file name is a fictional example.
Consultation using manuscripts and references
Find relevant passages in the same work's manuscript and references and receive an answer based on that content. Search capabilities within the work and the amount of manuscript, reference, and conversation content used in an answer are limited by your current plan.
Consultation using creative writing knowledge
On all plans, including Free, the AI can consult shared knowledge about plot, dialogue, character portrayal, and writing techniques when useful. It can search by meaning for material relevant to your question in your work's language, Japanese or English. Consider when a technique helps and its cautions, then choose ideas that fit your intentions. Semantic searches and AI responses use AI credits.
Manuscript and reference tags
Attach a manuscript, selected passage, or reference item to specify what the AI should consult. On Web, add a selected passage from its context menu. Adding a reference does not send the message; you can remove individual references before sending.
The Web context menu for selected manuscript text.
Choose Add to AI conversation to attach the selection to your message before sending.
AI operation status
On Web and iOS, follow searches, manuscript edits, and their results within the conversation. Open created or updated items at their current locations. On Web, review before and after in unified or side-by-side views when the history needed for that AI response remains available. Unavailable comparisons and truncated long text are identified.
The Web unified before-and-after view for a fictional manuscript change.
View changes opens the content created or updated by that AI response.
AI manuscript creation and editing
On Web and iOS, including Free, ask the AI to create or edit agreed headings and passages, append text, or move items. Ordinary changes have eight seconds before application; apply early or skip them. Broad replacements and manuscript deletions wait for explicit approval. Stopping the AI keeps changes already saved. After the run ends, Undo can revert the work changes from one request together. It does not rewind the conversation or refund used AI credits. AI processing uses credits.
Web confirmation before applying a broad manuscript rewrite.
It waits for approval. Choose Don’t apply to skip the change.
AI reference creation and organization
On Web and iOS, ask the AI to create or edit agreed text and structured references, rename items, create folders, move, or reorder them. Deletion, whole binary or structured-reference replacement, and structured row or hierarchy edits wait for confirmation. Ordinary changes have an eight-second grace period. PDF and Word files can be replaced with another saved file of the same format; generating or partially editing their internal text is not supported. AI processing uses credits, and saved references follow your current plan's storage and file limits.
The Web result list of updated manuscript and reference items with their current locations.
Select an item to open its current location and review it.
Retry sending or transcription
If sending a message or transcribing a recording fails, retry using the text or audio that could be retained.
Restore unsent messages
Keep an unsent message and its reference tags in the same browser tab. Restore the draft after reloading the page or switching conversations.
Copy, rate, and report AI responses
On Web and iOS, copy a finalized AI response and rate it good or bad. Switch ratings, or select the same rating again to remove it. Fixed creative assist greetings cannot be rated or reported. Report an inappropriate response by choosing a reason and adding up to 500 characters of details; Other requires details. You receive a receipt number, and resending a report for the same response does not create a duplicate. Removing a rating keeps the separate report. Copying, rating, and reporting do not use AI credits. Report evidence is normally deleted in monthly reviews after 180 days from case resolution, except when preservation is required.
The Web form for reporting an inappropriate AI response, separately from quality feedback, with a reason and details.
Other requires details. This example uses fictional data and simulated receipts; it does not send a real report to the operations team.
Read AI responses aloud
On Web and iOS, play or stop each finalized AI answer. Read the text without Markdown markers using the manuscript's shared method, AI voice, and speed. Standard voices use no AI credits; generating new AI audio uses credits.
Automatic response read-aloud
On Web and iOS, toggle the speaker icon in the conversation header. It defaults off and remembers your choice on the device. Read only new answers finalized after enabling it; opening past conversations does not play them. Wait during recording or transcription, and stop playback before recording or switching conversations or works. iOS also stops reading when the app is suspended.
The Web conversation header with automatic read-aloud enabled.
Use the speaker icon at the top right to read subsequent finalized answers.
Run the same request again
On Web and iOS, repeat the latest request if its AI answer was conversation only, with no manuscript, reference, or project-setting changes or generated images. Reuse the original request and AI model, replace the previous answer without duplicating your message, and use AI credits. On iOS, first save any local manuscript or reference drafts to the work. If another tab or device has updated the work, review its latest state before retrying. Available models follow your current plan.

Manuscript

Edit prose, organize chapters, manage ruby annotations, check length, and search and replace text.

12

Manuscript editor
Enter headings and prose in one continuous editor. Body text keeps spaces, blank lines, and line breaks, and can be saved empty. Leading and trailing spaces are removed from headings. The storage limits are 200 UTF-16 units per heading and 100,000 per body block; some characters, such as emoji, use more than one unit.

Add, delete, and reorder manuscript blocks
Add headings and body blocks based on the selected item. Drag items on Web, or use the up/down and destination controls under Manage on iOS, to change order and nesting. Confirmed deletion includes descendants; Undo restores their structure and text while the project exists. Manual edits themselves use no AI allowance, but automatic AI indexing after additions, deletions, and some other edits may use it.

Character and word counts
On Web and iOS, check the selected block, its descendants, and the whole work, with headings and body text shown separately. Counts follow unsaved input on the editing screen and can be hidden. The work's language determines the unit: Japanese counts character clusters, including combined characters, emoji, spaces, and line breaks; English counts words and excludes whitespace and line breaks. Ruby readings are excluded. Available on Free; counting itself uses no AI allowance.
Web counts for the selected body block, its descendants, and a fictional work, with headings and body shown separately and progress toward a body-only goal.

Writing length goal
Set, change, or clear one body-only goal per work, from 1 to 1,000,000,000 characters or words. In the manuscript editor, view the current length including unsaved input, remaining amount, completion percentage, and when the goal is reached or exceeded. Use the editor dialog on Web or a sheet on iOS. If another screen changes the goal, your input is kept while the latest value is loaded for review. Available on Free; manual goal settings themselves use no AI allowance.

Search names, terms, and aliases together
On Web and iOS, enter up to 100 names, places, terms, or aliases, one per line, and review labeled exact matches together. The app does not infer spelling variants or alias relationships, or save the list as a glossary or search history. This mode is for review; select one search string when you want to replace text. It uses no AI credits.
Web results labeled with each author-entered term.
Exact matches for explicitly entered spellings; relationships are not inferred.
Replace one match
On Web and iOS, replace a match only when its original text and position still match the current manuscript. The edit becomes a draft, then follows normal Web autosave or the iOS Save action. An empty replacement deletes the matching part; changes that empty a heading or body, split characters such as emoji, or exceed saving limits are rejected. Updating the AI search index after saving may use AI credits.
Bulk replacement with preview
On Web and iOS, save unsaved manuscript edits first, then replace within the selected saved scope. Review the affected blocks and counts, with before and after text for the selected block, then confirm. Going back skips the bulk replacement while keeping edits saved beforehand. If content or structure in the scope changes after preview, no matches are replaced; review the latest version again. Undo the confirmed changes together using the work's Undo control. Updating the AI search index after saving may use AI credits.

Fictional work example: review the proposed changes before applying them together.
Snippets
On Web and iOS, create, edit, and delete reusable short passages shared across your own works and devices. Available on Free; creating, editing, and deleting snippets use no AI credits. Updating the AI search index after saving the body may use credits. Keep up to 50 snippets per account, with names up to 60 and content up to 1,000 UTF-16 units (some characters, including emoji, use multiple units). Mixed Japanese and English, spaces, and line breaks are preserved without automatic translation or variable expansion. Insert at the body cursor or replace only selected text. The inserted draft follows normal Web autosave or iOS Save to work. Snippets are stored separately from work history; deleting one does not remove text already inserted. Web reordering is currently unavailable.

After you send at least one message, generate a report from the conversation using AI credits. Edit the preview before confirming a save to the work’s references. Closing the preview discards unsaved edits. Continue the conversation and generate a fresh preview when you are ready to review it again.

Save and update reports
Save the reviewed content as a new reference, or update a report previously saved from this same thread. For a new report, choose its file name and destination folder. An update is stopped if the target was changed elsewhere, protecting later edits from an outdated overwrite. Saved reports follow the work’s reference storage and plan capacity. They do not directly rewrite the manuscript or other settings references.

Reading and writing settings

Choose writing direction, fonts, text size, read-aloud voices, and playback speed.

9

Theme settings
Choose automatic, light, or dark appearance. Display settings are kept separately on each device.
Interface text size
Choose small, medium, or large interface text. Adjust manuscript text and controls to suit the device you are using.
Horizontal and vertical writing
Switch Japanese manuscripts between horizontal and vertical display. The direction is saved on each device. PDF and EPUB exports use horizontal writing.

Manuscript font
Choose a manuscript typeface and preview it before selecting. Font options depend on the work's language; Japanese options include Mincho, Gothic, and supported Google Fonts.
Toolbar labels
On Web, choose whether manuscript editing tools display their names or mainly use icons.
Standard read-aloud
On Web and iOS, read manuscripts or AI answers using device or browser voices. Play selected manuscript text or the current manuscript without AI credits. Available voices and languages depend on the OS and browser.
Natural AI read-aloud
On Web and iOS, listen to manuscripts or AI answers using generated audio. Generation uses AI credits and may take time to start. Reuse temporary audio for the same work, text, and voice settings; changing speed alone does not regenerate it. Browser storage lasts up to 24 hours, with up to 40 entries; iOS also retains results while the app is running. Expiry, capacity, and storage availability can prevent reuse. Recover audio lost in transit from the API for up to 24 hours. This audio is not permanently stored as work data.
Read-aloud voice and speed
On Web and iOS, choose the shared manuscript and AI-answer method, AI voice, and speed (0.75x, 1x, 1.25x, 1.5x, or 2x) in Writing workspace settings, saved on the device. AI voice options follow the work's language. Preview voices with matching prerecorded samples without AI credits. Changing the display language does not change the work's language.

Export and publication

Export manuscript files and manage a reader-facing version of your work.

14

Manuscript export scope
On Web and iOS, export saved Japanese or English manuscripts as a whole work or a selected chapter or body block and its descendants. Export is available on the free plan and uses no AI allowance.
Text, Markdown, and Word export
Export the manuscript as a text, Markdown, or Word (DOCX) file. Spaces, blank lines, and line breaks in the body are preserved. Font, vertical-writing, and ruby settings from the manuscript screen are not carried into the files.
PDF export
Create a horizontal PDF from Japanese or English manuscripts using A5, A4, Letter, or two-column A4 layout. Configure headers, footers, and page numbers. A font for the work's language is embedded; manuscript-screen font, vertical-writing, and ruby settings are not carried over.
Choose a PDF layout and the manuscript range to export in the Web app.
Choose a PDF layout and the manuscript range to export in the Web app.
EPUB export
Create a horizontal, reflowable EPUB 3 that adapts text to the reader's screen. An author name is required. Optionally choose a JPEG, PNG, GIF, or WebP image of up to 8 MB from the same work's references as a cover, with an image description. Manuscript-screen vertical-writing and ruby settings are not carried over.
Export history, downloads, and sharing
Generation continues after you close the screen or app. Check the same status and history on Web and iOS using the same account. Files are kept for seven days after generation completes. Download them on Web or use the device's share sheet on iOS. After expiry, create another export from the saved manuscript.
Publication visibility
On Web and iOS, choose private, unlisted, or public visibility for the whole work or a selected heading or body and its descendants. Available on the Free plan without using AI credits. Starting or updating an unlisted or public publication requires acceptance of the current public-content terms.
Set reader-facing work information and publication visibility in the Web app.

Published title, author name, and description
Set the title, author name, and description shown on the reader page. Edit them separately from the working project name.
Update published content
Publishing saves the current saved manuscript and the ruby readings used in its published scope. Further writing or ruby edits are not published automatically. Check whether unpublished changes exist and apply them with Update published content.
Share a publication URL
Copy a publication URL. Open an X post composer on Web, or use the device's share sheet on iOS. Anyone with an unlisted URL can read the work; regenerating that URL makes the previous link invalid.
Reader-facing work page
Read the title, author name, description, table of contents, manuscript, and ruby readings in a browser. Readers need no registration, sign-in, or app installation. Opening it from the iOS author screen also uses the device's browser.
Reading display and saved position
Switch between horizontal and vertical writing, text sizes, line spacing, backgrounds, and ruby visibility. Where browser storage is available, keep settings and reading position in the same browser. A publication update resets that work's reading position; settings and position do not sync across devices or browsers.
Read a published work aloud
Read Japanese or English works using a matching local device voice, from the visible paragraph to the end of its heading. Use ruby pronunciations and choose a voice and speed from 0.75x to 1.5x. A supported voice is required; no AI credits are used.
Contents and keyboard reading controls
Move through the table of contents or previous and next headings. Use the keyboard to scroll, change headings, control read-aloud, and open settings. Turn character-key shortcuts on or off.
Change or stop publication
Saving work information, visibility, or the published scope also updates the reader page to the current saved manuscript. Returning the work to private makes the reader page unavailable while keeping your working manuscript.

Plan comparison
Compare Free, Light, Standard, and Pro by price, AI credits, available AI, and reference, conversation, and response limits. Check prices where you purchase. The Mini campaign is Web-only at $3 per month for up to three charges, then ends automatically without switching to a regular plan. Signups close on December 16, 2026, at 20:00 JST.
Plan changes
Change your plan where you subscribed and check its effective date and remaining entitlement period. Upgrades take effect immediately and downgrades at the next renewal; billing and credit adjustments depend on the purchase provider. The same account shares plan entitlements and credits between Web and iOS.
AI credit grants
New accounts receive 1,500 credits in total: a 1,300-credit welcome bonus plus the first 200 Free credits. Later Free grants of 200 arrive on your next use after 30 days have passed since the previous grant; inactive periods do not accumulate grants. Paid-plan credits are granted for each payment-confirmed period.
AI credit balance
Check your remaining credits and the next expiration date. Credits normally last 90 days from each grant, and those expiring sooner are used first. Plan entitlements and credit expiration are separate. Earlier grants and purchases retain their original terms.

Illustrative grants and usage: filter by type and open AI usage details.
Add AI credits
Purchase additional credits on any base plan, including Free. Web purchases last 90 days, while additional credits purchased through the App Store do not expire. The purchase provider determines expiration; switching devices does not change it. Buying credits alone does not expand available AI or reference limits.
Restore iOS purchases
In the publicly available iOS app, recheck App Store purchases and sync plans or pending purchases associated with your current NovelShaft account. The same purchase never grants credits twice, and restoration does not bring back credits already used.
Subscription and payment management
Manage renewal and payment details in the payment-provider portal for a Web subscription or in the App Store for an App Store subscription. Stopping renewal keeps the paid entitlement period available. Deleting your NovelShaft account and stopping subscription renewal are separate procedures.
