Clipzen is a one-payment desktop app that turns long videos into short vertical ones. It transcribes the recording, picks the moments worth posting, and edits each into a finished short (follows the active speaker, cuts the filler, adds word-synced subtitles, b-roll and background music). The built-in AI runs on your own machine and is completely free. You can also plug in an OpenAI key instead, from about $0.03 per hour of video.
