Auto caption generator for shorts

Most short-form is watched on mute, so captions are not optional. But typing them out, timing each word, and styling them for the feed is the most tedious part of making a clip, and it has to happen for every single short.

Shortie generates captions automatically. It transcribes your clip, times the words, and burns in clean, animated captions styled for short-form. Paired with best-moment detection and speaker-tracked reframe, your clips come out fully captioned and post-ready, no typing required.
