Katto is a web-based video clipping tool designed to automatically transform long-form video content into multiple short-form clips suitable for social media platforms. Its primary function is to ingest a video via a YouTube link or direct file upload (supporting MP4, MOV, WebM, and MKV formats, with a limit of up to 90 minutes or 5 GB on the Pro plan) and then process it through several automated stages. The tool analyzes the video to identify engaging moments, reframes the footage for vertical 9:16 aspect ratios using face and scene tracking, generates word-by-word subtitles in 99 languages with proper noun correction, and optionally translates the audio into eight languages. The entire process, including transcription, virality scoring, and captioning, is designed to complete in approximately five minutes. The platform includes several distinct features. The AI clipping function automatically identifies and ranks segments of the input video based on predicted virality, scoring each clip on hook strength, flow, value, and trend relevance. The Miru AI Reframe engine tracks faces and scenes to dynamically switch between layouts and crops, ensuring subjects remain centered in the vertical frame without requiring manual keyframes. Additional capabilities include AI dubbing for multilingual output, an AI hook generator that creates a 3 to 7 word opening line, and a one toggle noise removal tool for cleaning audio. The system also offers cinematic camera smoothing, instantaneous scene change snapping, dynamic split screen for multiple speakers, and safe zone awareness to avoid awkward cropping. Typical use cases for Katto involve content creators, marketers, and media producers who need to repurpose long videos such as podcasts, gameplay streams, sports highlights, trailers, or wildlife footage into multiple shorter clips. The workflow is linear: the user pastes a link or uploads a file, the tool processes the video and presents a list of scored clips, and the user selects which clips to export. Exported clips can be directly published or scheduled across seven platforms including YouTube, TikTok, LinkedIn, Instagram, Bluesky, Mastodon, and Threads. The tool eliminates the need for manual timeline editing, caption typing, or multi platform re uploading. Technical requirements for using Katto are minimal beyond a modern web browser and an internet connection, as the processing occurs server side. The tool requires no credit card to begin, though a Pro plan is available for extended upload limits. The platform is accessed directly through its website at katto.tech, and no software installation is necessary. The AI models underlying the clipping, reframing, and scoring functions are proprietary to the service.
