Products & Services
Cloud service that accepts YouTube, Twitch, Vimeo, Rumble, Zoom, Dailymotion links or uploaded video, finds and scores strong moments, creates short clips, captions and reframes them, and supports publishing and scheduling.
REST and JSON API for submitting video jobs, polling status, retrieving clips and transcripts, checking usage, and using signed webhooks; API usage shares the account's monthly video quota.
Hosted MCP endpoint at mcp.katto.tech/mcp for Claude, ChatGPT, Cursor and other compatible agents, using OAuth 2.1/Dynamic Client Registration or bearer keys. It exposes 16 tools for the clipping workflow.
Command-line interface distributed through npm for running the Katto clipping pipeline from a terminal, script, or cron job.
Market Position
Katto positions itself as a lower-cost, flat per-source-video alternative to credit- or minute-metered AI clippers such as OpusClip, Submagic, Gling, Vizard, Klap, and similar tools. Its stated differentiators are 25 full source videos per month on Creator, transparent four-axis scoring, 99 caption languages, Twitch/gaming support, seven-platform publishing, and four agent surfaces (app, CLI, MCP, and API). Its own comparison content acknowledges that more mature competitors such as OpusClip have larger tool catalogs and more established agent workflows.

Founding Story
Katto was started in 2026 as a bootstrapped solo-founder project in Japan to make repurposing long-form video into short-form content a faster, more consistent workflow. The initial vision was to automatically find strong moments, rank them transparently, reframe them for vertical platforms, caption them, and make them ready to publish without credit or per-minute pricing.
