Claude’s favoriteflashcards.

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.

Next up — what is tachycardia?

“um… I think it's when your heart beats too fast? but I'm not sure”

That's correct — a resting heart rate over 100 bpm.

How it works

01

Tell your AI what you're learning

Paste notes, a chapter, a menu — or just describe it. Claude, ChatGPT, or Grok turns it into flashcards for you..

02

It handles the hard part

Every card is scheduled with spaced repetition — you see it again right before you'd forget it. No settings to learn.

03

You just study

A few minutes a day on the web — or out loud, with your AI asking the questions and grading your answers.

Works with your AI

Any assistant that speaks MCP can run Flash in chat —.

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.
