Katto

Katto turns long-form videos — YouTube links, podcasts, Twitch VODs, uploads up to 90 minutes — into ready-to-post 9:16 shorts in about 5 minutes, instead of a full day of manual editing. Key features: Miru, a scoring AI that grades every clip on hook, flow, value and trend, and surfaces the 10 best; word-by-word captions in 99 languages with AI proper-noun correction; smooth auto-reframing that tracks the action; one-click publishing to 7 platforms (YouTube, TikTok, Instagram, LinkedIn, Threads, Bluesky, Mastodon). What makes it different: it works on sports, gaming and multi-speaker shows — not just talking heads — and pricing is flat monthly: no credits, no expiring minutes, unlike OpusClip, Klap, Vizard or Submagic. What you can expect: one weekly 1-hour podcast episode becomes 10 ranked, captioned shorts, published everywhere in one click — a month of social content from four uploads.
