What Katto is
Katto is an AI video editing tool built for the short-video workflow. Paste a YouTube link or upload a file, and it watches the whole video, detects the moments most likely to perform, and rebuilds them as vertical 9:16 clips with verbatim subtitles in 99 languages. It corrects proper nouns in subtitles, generates topic tags, and exports SRT files for other editors. Each candidate clip is scored on hook, rhythm, value, and trend, so instead of scrubbing an hour of footage you start from a ranked list. The free version handles 2 videos up to 30 minutes in 720p per month, and Creator costs €12 monthly billed annually or €15 monthly for 25 longer videos in 1080p.
What you can do with it
- Convert podcasts, matches, and streams into vertical shorts
- Get automatic subtitles in 99 languages with proper noun fixes
- See which moments rank highest before you publish
- Publish to 7 platforms with one click or export SRT files
- Edit any generated clip in the built-in editor
Who it is for
- Podcast creators repurposing long episodes into clips
- Sports journalists cutting highlights minutes after a match
- Game streamers turning livestreams into highlight reels
What to watch out for
The free tier is deliberately small: 2 videos, 30 minutes, and 720p per month, which will not sustain a daily posting schedule. Processing takes about 5 minutes per video, so last-minute edits need planning. Watermark removal, 1080p output, and face tracking are locked to the Creator plan, and pricing may change. Subtitle accuracy should be spot-checked, especially for names and technical terms. When quality matters, export a small draft first to confirm the result before producing the final file.
