Create subtitles from your own media

Open a supported audio or video file and create original-language subtitles. Polyglot recognizes speech automatically across 25 supported European languages.

A Mac subtitle editor for the finishing touches

Watch or listen alongside your subtitles. Correct names and punctuation in place while preserving the cue timings. AI output needs human review, especially with overlapping voices or rapid dialogue.

Export a format you can use

Save UTF-8 SRT subtitles for compatible video editors and players. SRT is a separate subtitle file; it does not burn captions into your video.

Frequently asked questions.

Can I generate subtitles without uploading my video?

Yes. After downloading the subtitle models, transcription runs on your Apple Silicon Mac.

Can I add subtitles to an MP4?

You can transcribe a supported MP4 and export an SRT file. Add that SRT in a compatible editor or player to display the subtitles.

Can I create subtitles in other languages?

Yes. Select translation languages before processing or work with the original-language transcript. Review translated text before exporting.
