More room to write on existing plans
Updated September 18, 2026: The expiry information below now reflects the 90-day validity period. See what changed and how existing credits are treated.
Light, Standard, and Pro keep their monthly prices and gain more AI credits.
- Light: USD 15 per month, 4,500 monthly credits
- Standard: USD 30 per month, 9,450 monthly credits
- Pro: USD 90 per month, 29,700 monthly credits
Paid-plan credits issued under the new terms remain valid for 90 days from each grant. Each grant keeps its own expiry, including after cancellation. Available AI follows your current plan.
Under the unified validity terms, Free credits, welcome and badge rewards, and additional purchases through the Web or Google Play are also valid for 90 days from each grant. Additional App Store purchases do not expire. Grant quantities and the 30-day Free grant cycle stay unchanged. Previously issued credits and earlier purchases keep their original terms.
