A culture worth protecting. Building its future from Japan.
Light novels were born and nurtured in Japan. NovelShaft keeps exploring new writing experiences to help shape what comes next for this culture.
OTAKU culture’s deep love of stories and dedication to the details guide our work. Authors stay in control as we turn advances in AI into more ways to think, write, and develop a novel.

Reference storage capacity compares the total storage, number of files, and maximum size of one file for each work.
Reference and conversation context available to AI includes relevant-passage searches, text excerpts, reference material, and recent conversation passed in one response.
Long AI response limit is the technical maximum amount of text AI can produce in one response. It does not mean every response will use the full limit.
Current storage, file-count, searchable-text, and output limits are available on the plan-change screen after you create an account.

Questions
Can I try it without paying?
Yes. New accounts receive 1,300 welcome credits plus 200 Free credits, for 1,500 credits valid for 90 days. No payment information is required. Use varies by AI model and action. The welcome credits do not renew. While on Free, another 200 credits are granted on the next use at least 30 days after the previous grant; each grant remains usable until its own 90-day expiry.
How is my creative data handled?
Rights you hold in manuscripts and material you enter, create, or upload remain with you. Creative content is not used for unrelated advertising, to train a general-purpose model owned by the Operator, or to create datasets for other users. AI output may contain errors or resemble existing work. Review it before publishing or selling it. Terms of Service · Privacy Policy
Does the AI write the whole novel for me?
No. AI can ask, organize, suggest, and draft when requested. You can skip a limited change during its five-second window, inspect it afterward, and use project-wide Undo. High-risk actions such as deletion require explicit approval. The author decides what remains.
How is NovelShaft different from a general AI chat?
The conversation, manuscript, outline, and reference material belong to the same project. Useful results can remain with the work and support later writing.
Can I start with a draft already in progress?
Yes. Start with a scene or character, or bring an existing draft and reference material into a project. Typed and spoken input are supported.
Will NovelShaft catch every continuity error?
No. AI can help compare available manuscript and reference context, but complete or automatic contradiction detection is not guaranteed.
Can I take the manuscript elsewhere?
Yes. Export all or part of the manuscript as Text, Markdown, Word (DOCX), PDF, or EPUB 3. Keep it private, share a link-only page, or publish it.
Where can I use NovelShaft now?
The Web app is verified on desktop Google Chrome. The iOS app is available on the App Store for iPhone and iPad, using the same account and works as the Web app. Explore the mobile app. The Android app is being prepared for release.
