Who it's for

Frequently asked questions

What is Recarve?

Recarve is a spaced repetition app based on the Ebbinghaus forgetting curve. Add what you study as cards, get review reminders at set intervals, and let AI create summaries and review questions from photos, PDFs, and text.

What is spaced repetition?

Spaced repetition is a study method that increases the interval between reviews so you revisit material just before you would forget it. The Ebbinghaus forgetting curve shows that memory fades quickly over time, but repeating at the right moments helps it last.

How are review intervals decided?

You choose one of four built-in templates — Quick Memorize, Long-Term Memory, Concept & Theory, or Formula & Problem Solving. For example, the Long-Term Memory template sends 8 reminders at 10 min, 30 min, 2 hr, 1 day, 3 days, 7 days, 14 days, and 30 days.

Can I create cards from photos or PDFs?

Yes. AI can analyze photos, PDFs, and text to create a summary and review questions automatically, or you can type a card manually. AI analysis uses credits; even without credits you can keep creating manual cards and reviewing.

Are my photos and text stored on a server?

No. Images and text sent for AI analysis are used only temporarily for processing and are not stored afterward. The study cards themselves are stored only on your device.

Will I get reminders at night?

If you set Quiet Hours, any reminder due during that period is automatically pushed to right after it ends.
