**Quick Mode:** pick a template, drag and drop your videos (as many as you want), and it batches them automatically. Handles mixed codecs/aspect ratios/resolutions in a single batch.

**Project Mode:** for when you want to review and edit. Correct words, adjust timing phrase by phrase, or word by word on a waveform timeline. See your corrections live on the video in the editor. Scene-cut detection flags captions that straddle a cut so you can fix them before burning.

**Exports** SRT, VTT, ASS and TXT files, MKV's with soft captions, or videos with burned in captions however you configure them (standard captions, word by word, highlights, different colors/fonts/sizes/locations).

The free version can do the full editing workflow but exports are limited to the first 30 seconds with a small watermark on burned video. There’s a 30-day full Pro trial built into the app, no card required. Lifetime Pro is a one-time purchase, $14.99 launch price, no subscription ever.

Apple Silicon only.

I built a Mac app for local AI captions because I wanted karaoke style subtitles without a subscription, it grew from there.
