Flashcards for Claude.

Flash is a spaced-repetition flashcard app Claude can drive. Connect it once as a custom connector, then just talk: Claude writes cards from whatever you're learning, asks you the questions out loud, grades your answers, and Flash schedules the next review with FSRS.

What Claude can do once it's connected

Make the cards

Paste a chapter, lecture notes, a vocabulary list, or just describe the topic. Claude turns it into a deck of clean question-and-answer cards in Flash.

Quiz you by voice

Say “let's study cardiology.” Claude asks each due card, listens to your answer, and tells you whether you got it: strict on numbers, doses, and names.

Grade and schedule

Every answer is rated Again, Hard, Good, or Easy and handed to FSRS, so you see each card again right before you'd forget it. Nothing to configure.

Why not just ask Claude to quiz me?

You can, and it works. For one session. Then the chat scrolls away and everything you drilled goes with it. Flash gives Claude a memory: every card, every answer, and every review date lives in your account, synced across devices, exportable to Anki or CSV whenever you like. Tomorrow, or next month, Claude picks up exactly where you left off and asks only what's due. The full walkthrough is in how to make flashcards with Claude and study them by voice.
