Katto

Katto is a clip finder tool that turns long videos into scored, captioned vertical clips on flat pricing. Katto turns YouTube links and uploaded videos into ranked, captioned 9:16 clips with four-axis virality scoring, AI reframing, dubbing and scheduled publishing to seven platforms, priced per video instead of credits.

Katto is a video clipping service that converts long recordings, such as podcasts, interviews, sports footage, gaming streams and trailers, into short vertical clips ready for social feeds. A user pastes a YouTube link or uploads an MP4, MOV, WebM or MKV file, and the system detects the strongest moments, crops them to 9:16, adds captions and returns a ranked shortlist instead of a raw timeline. The ranking is the central idea. Each clip receives a score out of 100 built from four axes: hook, flow, value and trend. Because the breakdown is visible, a creator can see why a moment was ranked high rather than trusting a single opaque number. Clip selection can also be steered with a prompt, by intent, topic, hook or audience angle, instead of relying on generic moment detection. Editing happens in a browser editor where the automatic choices stay adjustable. Reframing follows speakers, faces and action and can output 9:16, 4:5 or 1:1, with speaker detection and split-screen layouts for dialogue. Captions cover 99 languages, with precise word timing in 41, and there are 51 caption styles on the Creator plan. Other tools include a scroll-stopping hook, AI B-roll, animated emojis, silence removal, vocal cleanup, brand templates and text-based editing, where deleting transcript text removes the matching footage. AI dubbing into 19 languages is included on the Creator plan, with watermarked output noted for dubbed clips. Publishing is handled in the same place. Clips can be sent to seven platforms, including YouTube, TikTok, Instagram, LinkedIn, Threads, Bluesky and Mastodon, either immediately or on a schedule. A REST API with an OpenAPI 3.1 description, webhooks and an MCP server let developers and AI agents trigger clipping programmatically. Pricing is the main point of difference from credit-based competitors such as OpusClip and Klap. Plans count videos per month rather than minutes, so a long episode costs the same as a short one. That suits podcasters, streamers, sports and gaming channels, and small marketing teams who publish clips regularly. A free tier exists for testing, while a higher Studio tier with 4K export and team seats is listed as coming later.
