On-device captions
Captions from your voice, without sending it anywhere.
Most videos are watched with the sound off, and most caption tools upload your audio to make them. SmoothCut downloads a speech model once and does the work on your machine.
- Word-timed subtitles from your voice
- The model runs on your computer
- Works offline after one download
- The language is detected automatically
How it works
On-device captions, step by step
- 01
Download a model once
Pick a speech model — the recommended one is about 75 MB — and it is saved on your computer. From then on, captions are one button.
- 02
Nothing leaves your machine
The audio is transcribed locally. There is no upload, no queue and no per-minute charge, and it works on a plane.
- 03
The transcript does more than captions
The same transcript is how SmoothCut finds filler words and abandoned takes, so they can be cut for you.
On-device captions: questions
Do captions need an internet connection?
Only for the first download of the speech model. After that they are generated offline.
Is my audio sent to a server?
No. Transcription runs on your own computer.
Which languages are supported?
The speech model detects the spoken language automatically. You can choose a larger model than the recommended one for more accuracy, at the cost of a bigger download.
