Turn one long video into weeks of scored, captioned vertical shorts.
Every detected moment is scored 0-100 on hook, flow, value and trend, so clips arrive as a ranked shortlist instead of a random selection.
Clips are reframed automatically to 9:16, 4:5 or 1:1, with the active speaker, faces and action kept in frame across multi-speaker shows, sports and gaming.
Word-synced animated captions in 99 languages (precise timing in 41) and AI dubbing into more than a hundred languages with a natural voice.
Katto transcribes your video so you can cut by deleting or reordering text; the cuts follow the transcript like editing a document.
Turn long videos into viral TikToks, Reels and Shorts in one click
AI scans the transcript of your long video or YouTube link, extracts the most interesting topics and returns multiple vertical clips in minutes.
Scene-aware reframing keeps the active speaker or key action centred, with split-screen, screencast and gaming layouts for 9:16 output.
Transcription and word-highlighted subtitles across 99+ languages, with custom fonts, colours, logos and AI-drafted caption copy.
Every generated clip receives a score of its viral potential so you can decide what to publish first instead of guessing.
