FSRS — the gold standard

The same algorithm that powers Anki, trained on hundreds of millions of real reviews. BrainFlip builds a personal memory model for every card you study.

  • Hard cards come back sooner
  • Easy cards spaced out weeks or months
  • Set a maximum gap before exams to stay sharp
📊

Progress you can see

Stay motivated with a full-year activity heatmap, daily study streaks, per-deck maturity bars (New → Learning → Mature), and achievement badges.

  • Daily streak to keep you consistent
  • Maturity breakdown per deck
  • Achievements for milestones
🌍

Your data syncs to the cloud via Supabase. Start on your laptop at school, continue on your phone at home. Always in sync, no setup required.

  • Works in any modern browser

🔁

Cram mode

Exam tomorrow? Cram mode cycles through every card in a deck without scheduling — rapid-fire review to refresh everything before a test.

🎨

Dark, Light & Fun themes

💡

In-session AI assist

Stuck mid-study? Ask for a Hint (a nudge toward the answer) or an Explanation (a full breakdown) — without just giving you the answer.
