Upload a recording, podcast, or stream VOD — or point the tool at a URL where supported.
The tool transcribes the audio, scores segments for energy and topic shifts, and proposes the clips worth keeping.
Clips are auto-cropped to vertical, with animated captions and the speaker kept in frame.
Approve the picks, tweak captions or cuts, and export ready-to-post files.
Transcription plus scoring finds the segments most likely to perform as shorts.
Speaker tracking keeps faces centered when cropping landscape to 9:16.
Word-by-word captions in the style viewers expect from top short-form creators.
Some tools generate full videos from a script — stock visuals, voiceover, and captions included.
Process whole back-catalogs into clip libraries instead of one video at a time.
Sized and formatted for Shorts, Reels, and TikTok out of the box.
