## What is Index?

Index is the modern Anki alternative that doesn't dump 500 cards on you on day one.

Generate flashcards instantly with AI from any topic or PDF, import your existing Anki decks in seconds, and study on FSRS-5 — the same algorithm Anki uses — in an app that paces new cards for you so you're never overwhelmed.

WHY STUDENTS ARE SWITCHING
• AI card generation from any topic, PDF, or your own notes
• Import Anki decks in seconds — your scheduling history comes with you
• Daily pacing keeps new cards manageable — no 500-card day one
• Streak, daily due count, and a 7-day forecast — free, not paywalled
• Undo, bury, and cram mode for the days before an exam
• FSRS-5 spaced repetition, done right
• Sync across all your devices automatically

A GENEROUS FREE TIER
5 decks, unlimited cards, 10 AI generations/month, 5 PDF imports/month, and unlimited Anki imports — free, forever. Upgrade to Pro for unlimited AI generation, unlimited PDF imports, and deeper analytics (decks at risk, hardest cards, full history) for less than $3/month billed yearly.

Perfect for exam prep, language learning, med school, law school, or memorizing anything that matters.

### 4/5 — Essentially Anki but Mobile.

*2026-05-29*

The app itself works sufficiently, although tapping to edit a card is not refined as you need to drag the text bar with your space key.  You cannot edit the SSR intervals to your liking, and the cards unfortunately cannot be shuffled; I hope these get remedied soon. Otherwise, it’s perfectly functional and has a nice interface.
