What you get

Built around what learners asked for.

01 · You remember it

Ready on the day.

Give a deck your exam date and Bunshu plans every session so you walk in remembering it. It schedules with FSRS, the open-source memory model, fitted to your own reviews.

Est. 96% on 12 Dec · target 95%
Memory in Stats: recall by day, the target reached on 24 OctoberToday with the day's session done and the next one named
02 · Never a pile

Miss a week. No backlog.

Every day is one session, sized to the minutes you have. Come back after time away and Bunshu eases you back in, so you never open the app to 900 due.

8 minutes means 8 minutes
Today after a week away: a session of the usual size, and two ways to catch upToday on a rest day: no session, and when the next one is
03 · Nothing to set up

Your first card in a minute.

No settings to learn, no add-ons to hunt for, and no account to make. Tap Continue without an account and start. Your cards stay on your phone until you choose to sync.

Fair questions

Before you try it.

I already have years of cards in Anki.

Bring them. Your decks import with their images 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, 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 with a clear finish, there's no streak to lose, and a missed day never punishes you.

What if Bunshu starts charging for the basics?

Unlimited cards and reviews are free on every plan, in writing. Export everything whenever you like, and nothing you made is ever deleted if you stop paying.

FAQ

Quick answers.

Is Bunshu really free?

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$79.99 a year.

Do I need an account?

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.

Which devices does it run on?

iPhone, Android and the web, with tablets supported. Studying works fully offline and syncs when you're back online.

Is my material used to train AI?

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.

Can I study in any language?

Yes. Your cards can be in any language. The app itself is in English at launch.

When can I use it?

Bunshu is estimated to launch in early 2027. Join the waitlist and you'll be among the first to try it, free.
