macOS

Speak it, see it written.

Turn speech into text in real time on your Mac, with punctuation and translation along the way. Recognition and translation run entirely on-device, offline. Your voice stays on your Mac.

What it does

01

Words as you speak

See a live draft while you speak. Finish a sentence and it is finalized with punctuation, ready to read.

02

On-device recognition

SenseVoice recognizes Mandarin, Cantonese, English, Japanese and Korean. Switch to the high-accuracy Fun-ASR-Nano model for accents and noisy environments.

03

On-device translation

Automatically translate each completed sentence into Chinese, English, Japanese, Korean, French, German, Spanish, Russian and more. Sentences already in the target language are not translated again.

04

Completely offline

Once the models are downloaded, recognition and translation need no connection. Your voice and text are processed on your Mac.

05

A native Mac experience

Record from the toolbar (⌘R), toggle translation with ⌘T, clear with undo using ⌘K, and find with ⌘F. Copy everything in one click or export as text.

06

Use with peace of mind

No ads, no in-app purchases, and no data collected.
