How do I generate subtitles for a video?

Drop the video, choose the language spoken and click Transcribe. Download the SRT (or VTT) file: each subtitle is timed on the speech and cut into one or two readable lines.

How do I add the SRT to my video?

YouTube: Studio → Subtitles → Upload file. VLC: drag the SRT onto the video. Premiere, DaVinci Resolve, CapCut: import it as a caption track.

Can I translate the subtitles?

Yes. After the transcription, send the SRT to the subtitle translator with one click: English ↔ French, Spanish, German, Italian, Portuguese or Dutch, also in your browser.

Is my recording uploaded?

No. Whisper, the speech recognition model by OpenAI, runs inside your browser (Transformers.js). The audio never leaves your device; only the model itself is downloaded, once.

How long does it take?

In Fast mode, about a quarter of the audio's length on a recent computer (15 minutes for 1 hour). Precise mode is 2 to 4 times slower without a graphics card. Transcribing only a part with the handles is faster.

Which languages are supported?

French, English, Spanish, German, Italian, Portuguese, Dutch, Arabic, Turkish, Polish, Russian, Ukrainian, Chinese, Japanese, Korean, Hindi and Swedish. Choose the language spoken before transcribing.

Everything about automatic subtitles

Why subtitle your videos?

Most social videos are watched without sound, and subtitles make them accessible to deaf and hard-of-hearing viewers. They also help viewers who speak another language, and the text is indexed by YouTube and search engines.

SRT or VTT?

SRT is the universal format: YouTube, Facebook, VLC, video editors and TVs read it. VTT (WebVTT) is the web standard used by HTML5 video players. Both contain the same timed lines.

Subtitle, then translate

Generate the subtitles in the language spoken, then send the SRT to the subtitle translator: in a few minutes you have subtitles in another language, without anything ever leaving your computer.

Tips & guides

Subtitles people can read

Subtitles are cut at two lines of about 42 characters and at most 7 seconds, the usual reading limits: no wall of text on screen.

Re-read names and technical terms before publishing: a quick pass in a text editor or in YouTube Studio is enough.

Pro tip

100% private

The speech model runs in your browser: your recording is never uploaded, stored or listened to by anyone.

Safe for interviews, medical or legal recordings, meetings and anything confidential.
