Recarve User Guide

A step-by-step guide to the basics of Recarve, from creating cards to reviewing and backing up.

Step-by-step guide

  1. Get started and sign in

    A short onboarding appears on first launch. You can browse cards, review, and create cards manually without signing in; sign-in is requested only when you use AI analysis. Apple, Kakao, Naver, and Google accounts are supported.

    Sign-in screen

  2. Create a review card

    Open the card creation screen with the add button on the home screen. Enter a title, then type your content or open the Generate with AI tab to take a photo or choose one from the gallery or a PDF. You can combine up to 5 photos in one card. AI extracts the text and creates a summary and review Q&A.

  3. Choose a review schedule (template)

    Pick the template that matches your material: Quick Memorize or Long-Term Memory for vocabulary and terms, Concept & Theory for explanations, Formula & Problem Solving for equations and worked problems. Your first reminder is scheduled as soon as you save.

    Template selection screen

  4. Review with reminders

    When a reminder arrives, try to recall the content first, then open the card to check. Tap Reviewed if you remembered it, or It was hard if you struggled. Both advance to the next stage; "It was hard" is recorded separately in your stats. Use Snooze to push the reminder back — the stage stays the same and nothing is logged in your review history.

  5. See upcoming reviews at a glance

    The schedule screen lists every card's next review time in chronological order. On the home screen, use status filters and search to find cards.

  6. Set Quiet Hours

    Set the start and end time in Settings → Quiet Hours. Reminders due during that period are automatically pushed to right after it ends.

  7. Check stats, levels, and badges

    Each completed review earns Rep, and your level rises with total Rep. Earn badges for study streaks, and share your stats card as an image.

  8. Back up data and switch devices

    Automatic sync is not supported yet. Save a JSON file via Settings → Data management → Export, then restore it with Import on your new device.

Frequently asked questions

What happens if I don't respond to a reminder?

The same-stage reminder keeps repeating until you respond. Tap Reviewed to move to the next stage and schedule the next reminder.

I'm not getting reminders. What should I check?

Check that notification permission is on for Recarve and that you're not inside your Quiet Hours. On Android, exclude Recarve from battery optimization so scheduled reminders aren't delayed. If they still don't arrive, open the app once and it will resync the schedule.

What's the difference between Reviewed and It was hard?

Both advance to the next stage the same way. The only difference is that It was hard is recorded in your stats so you can see which cards were especially tough.

How many credits does AI analysis use?

A photo uses 1 credit by default, and content-dense images may use more to match the amount of content. Analysis that fails because no text is found is not charged, and the first regeneration with the same input within 5 minutes is free.

How large a PDF can I upload?

Up to about 54,000 characters (roughly 30 pages of typical text). Scanned PDFs without text are analyzed as images, up to the first 5 pages.

Can I move my cards to a new device?

Save a JSON file via Settings → Data management → Export, then restore it with Import on the new device.
