Live subtitles in your browser, plus batch subtitles for your own media files

Browser Live Subtitles

Watch any video in your browser and read it in your language. The extension captures the tab's audio, transcribes it live and translates on the fly — or load your own .srt / .vtt file and it is rendered over the video. No re-uploading, no leaving the page.

Offline Subtitles

Upload your own video or audio file and get back a finished .srt or .vtt. Built for long recordings, lectures and archives — up to 5 GB per file. There's no rush, so it can take the slower, more accurate path, and it costs less per minute than live subtitles. Keep the file, then load it in the extension to display subtitles over any video.
