Claude’s favorite
flashcards.
Flash is a flashcard app your AI can use. Tell Claude, ChatGPT, or Grok what you want to learn — it writes the cards, schedules the reviews, and quizzes you. You just remember more.
Every card is scheduled by FSRS, the modern spaced-repetition algorithm that models your memory and shows you each card right before you'd forget it — the fewest reviews for the most retention.
How it works
Works with your AI
Any assistant that speaks MCP can run Flash in chat — set yours up.
Nothing gets lost.
No more losing important questions and context right when your exam is coming up. Everything you study with your AI lands in Flash — secure, synced, and yours forever.
No clutter. Just the next card.
Built for focus: one card, four buttons, and a scheduler that gets the most out of every minute you give it.
