Questions

Is my video uploaded?

No. The speech recognition runs inside your web browser, so your video never leaves your device.

Which languages are supported?

The AI recognizes about 100 languages and can detect the language automatically. It can also translate the speech into English subtitles.

How long can the clip be?

The free online tool handles the first 2 minutes of one clip. The first run downloads the AI model (about 40 MB) once. For full-length videos use Smart Media Player for Windows.

What can I do with the SRT file?

Load it in your video player, or upload it with your video to YouTube and other platforms as a subtitle track.
