What it does
This tool takes a long YouTube video and turns it into short vertical clips for TikTok, Reels or YouTube Shorts.
It writes out the speech with Whisper, an AI that turns speech into text, then uses a language model to find highlights. Each clip gets a score, an opening hook and a short reason it was chosen. It then crops the video to a vertical shape, following faces.
By default it uses the paid MuAPI service; a local mode does most work on your computer but still uses OpenAI or Gemini for picking highlights.
Who it's for
Video creators and agencies who want to make short clips from long videos.
