Subtitle generator FAQ
Is this subtitle generator really free?
Yes. There is no account, no watermark and no limit on minutes or files. Speech recognition runs on your own device, so it costs us nothing to let you use it as much as you like.
Is my video uploaded?
No. Your video and its sound stay on your device. The only download is the speech model, the first time you use it; your browser keeps it for next time.
Which languages does it understand?
About 100, including English, Spanish, Chinese, Japanese, Hindi, French, German, Portuguese and Korean. The spoken language is detected automatically, or you can choose it. You can also translate the captions into English.
Fast or Accurate: which should I choose?
Fast is a smaller model that handles clear speech well. Accurate is about three times larger and slower, and makes fewer mistakes with accents, background noise and languages other than English.
How long does it take?
It depends on your device and the quality you choose. On a recent laptop, Fast usually takes well under the length of the video. Browsers with WebGPU run it faster. You see the progress and the time left, and can cancel at any time.
How do I add the SRT file to YouTube?
In YouTube Studio, open the video, choose Subtitles, add a language, then Upload file and pick the SRT. Most video editors, such as Premiere Pro, DaVinci Resolve and CapCut, import SRT too.
Can I restyle subtitles I already have?
Yes. Drop an SRT or VTT file together with the video to edit the captions, change their style and burn them in, without transcribing again.
