Frequently asked
1. How does the free AI allowance work?
Free accounts include 5 AI generations per calendar month. FSRS review, manual card building, imports, stats and the forgetting curve don't use this allowance and are always free. The allowance resets at the start of each month; Pro removes the AI generation limit.
2. How can I use text from a PDF for AI cards?
Direct PDF import is not supported. Copy the text you need and paste it. Only the text you choose to convert is sent through our secure server to AI providers to draft cards; the original file never leaves your device and the text is not retained by us after your cards are generated.
3. What happens if I lose connection or a rating fails to save?
In an already open review session, if a rating fails to save and there are more cards to review, a message is shown and you can continue to the next card. Continuing does not mean the rating was saved successfully.
4. Can I migrate from Anki / Quizlet?
Arrange your cards as CSV (front,back[,tags]) before importing. Direct .apkg import is not supported. Cards are added following the deck structure, given an initial FSRS state, and enter normal scheduling right away.
5. How do I cancel my subscription?
On iOS: Settings → Apple ID → Subscriptions. Cancellation takes effect at the end of the current billing period; Pro stays usable until then. Refunds are handled by Apple under their policies.
6. How do I delete my account?
In the app: Settings → Account → Delete account. Deletion permanently removes your decks, cards and review history; the request is completed on our servers within 30 days.
