Spaced repetition flashcards
Bunshu brings each card back just before you'd forget it, in one session sized to your time. Miss a week and nothing swamps you. Nothing to set up.
Free to study. No card details. Unsubscribe any time.
Estimated launch early 2027: join the waitlist to get it first, with the odd update before then.
A short film with music and on-screen captions. Came back to 900 due? Skip a few days and most flashcard apps overwhelm you. Bunshu never lets them pile up: one session a day, sized to your time. One short session, a clear finish: rate each card, and Bunshu decides when it comes back. Miss a week? No backlog: cards reorganised, and faded ones return gently. Your notes, made into cards: labelled, sourced, and for you to review before they're saved. Bring your Anki decks: images and review history come too. No account, no ads, yours to keep: study as a guest, and export everything, free. Be the first to try Bunshu, at bunshu.com. Estimated launch early 2027, on iPhone, Android and the web.

What you get
Every session is the cards that fit the minutes you set. Come back after time away and it's the same size: the cards that waited come first, most faded first, and new cards wait their turn. You never open the app to 900 due.
8 minutes means 8 minutes
Give a deck your exam date. Bunshu says how ready you'll be, On track or Behind, and if you're behind it lists what would fix it, with numbers: an hour more a week, a later date, a lower target. The day before is one full pass, so exam day has nothing left to cram.

No settings to learn, no add-ons, no tutorial, and on your phone no account to make. Pick a deck, tap Start. FSRS, the open memory model, fits itself to your reviews.
Study as a guest · nothing saved to servers
How much you could recall today, and the day you'll reach your target. A calendar of your study days, with no streak to lose. Progress per deck. Plus adds Strong and weak and Learning patterns: your weakest topics and cards, what's slipping, your best hours, when your recall drops in a sitting, each ending in what to do.

Add lecture notes, slides, a PDF or a photo of your handwriting. Bunshu shows what it understood, drafts three cards for your OK, then every card points to the line it came from and a second model checks it. Nothing is saved until you say so.
Decks import with their images, audio, tags and review history, so nothing starts over. Quizlet exports and spreadsheets too.
Place your sessions in Schedule, with a reminder at each and quiet hours while you sleep. Bunshu fills every session and never moves one. Heads Up advises; you decide.

Fair questions
I already have years of cards in Anki.
Bring them. Your decks import with their images, tags and review history, so Bunshu knows what you already remember and nothing starts over.
AI flashcards are full of mistakes.
That's why Bunshu never saves one you haven't seen. Every AI card is labelled, points to the line it came from, is checked by a second model, and waits for your OK. Typing your own is free and unlimited.
I've fallen off flashcards before.
Most people quit over the pile and the chore. Here a session ends in minutes on a clear finish, there's no streak to lose, and a missed week never punishes you.
What if Bunshu starts charging for the basics?
Cards, reviews and every way of studying are free on every plan, in writing. Plus adds AI without limit, generated audio and deep Stats, nothing you need to study. Export everything whenever you like.
Who can read my cards?
No one but you. They're encrypted on the way and on the servers; we see only what you publish or report. The AI reads your notes only when you ask it to draft, and your consent names the companies first.
I'm learning a language. Does it do audio?
Every card reads aloud in your phone's own voice, free, offline, hands-free if you like. Vocabulary cards fill their own reading, spoken clip, example sentence and picture, for you to check (Plus, with 20 free).
FAQ
Yes. Making cards, studying and every way to review are free and unlimited, with no ads. Plus adds unlimited AI drafting, generated audio, deeper stats and more storage, for US$9.99 a month or US$59.99 a year.
Not in the iPhone and Android apps: continue as a guest, and nothing is saved to servers. The web app needs a free account, as does keeping your cards in sync across devices.
iPhone, Android and the web, with tablets supported. Studying works fully offline and syncs when you're back online.
No. Your notes are read only to draft your cards, by providers that keep nothing after the job. You're asked before anything is uploaded.
Yes. Your cards can be in any language. The app itself is in English at launch.
