How it works

Four steps from spoken word to something you remember

1

Record or import

Capture a conversation with the mic, or bring in an audio file you already have.

2

Extract & translate

Choose a JLPT level, N5 to N1 — ben-kyo finds matching vocabulary in the transcript and translates it.

3

Study, the smart way

Saved words become flashcards, scheduled with the same spaced-repetition algorithm Anki is built on.

4

Talk it through

Generate a short practice conversation from your own words, at the level you're studying.

Try a card

This is what Study looks like

Private by design

Nothing you record ever leaves your phone

No account

Open the app and start — there's no sign-up, no login, nothing to configure.

No server

Transcription, translation, and vocabulary matching run on Apple's on-device frameworks.

No tracking

No analytics, no third-party data sharing — there's simply nothing to collect.
