A professional recorder, down to the details
Never lose a second
Record with the screen off and in the background, with pause and markers. If the battery dies, at most a second is lost and the recording recovers on its own.
Live text, synced player
See the text appear as you record. Play it back with the current sentence highlighted, tap any sentence to jump there, from 0.75× to 2×.
Speakers · Pro
Separated and named. Set how many people spoke, merge two with a tap and, if you want, let it remember voices.
Summary and tasks · Pro
Decisions, open topics and tasks with owners and dates, generated by AI on this phone and labelled as such.
Dictation
Speak and the text appears, with voice commands in each language: new paragraph, period, comma, delete that.
One search
Titles, transcripts, summaries and tasks in one search. Every result jumps to the exact second.
On your wrist · Pro
Record on your Wear OS watch from the app, a tile or a complication. The audio moves to your phone and is transcribed there.
Phone, foldable and tablet
List and transcript side by side when unfolded, tabletop mode when half open. Light and dark theme, TalkBack.
Quality measured, not promised
We measured every language with the app's own transcription pipeline, and we publish the result — the same table you'll find inside the app. Lower error is better.

Error = WER (share of words wrong) or CER (share of characters wrong, for Japanese and Chinese), on read speech from the FLEURS set, 5 sentences per language, on high- and mid-range phones. Indicative figures, not a guarantee. Very good: up to 10%; good: up to 20%.
Danish, Swedish, Norwegian, Korean and Hindi are marked beta: they work, but expect more corrections. On entry-level phones, Norwegian, Turkish, Hindi, Japanese, Korean, Vietnamese and Chinese use a lighter model and are shown as beta too.
