About Katto

Katto is an AI video clipper that turns long-form videos into post-ready short clips by finding the best moments, reframing them vertically, adding captions, and preparing them for publishing. It scores every moment across hook, flow, value, and trend, then ranks clips by viral potential so users can focus on the strongest candidates. Its editor shows everything the AI applies, including reframing, speaker selection, captions, hooks, B-roll, and emojis, with every element remaining editable. Smart reframing follows the most important subject shot by shot, detects speakers in dialogue, and supports 9:16, 4:5, and 1:1 layouts, including multi-face and split-speaker formats. Prompt-first clipping lets users tell the AI what they want by intent, topic, hook, or audience angle rather than relying only on automatic moment detection. Katto transcribes videos for text-based editing, so deleting or reordering text updates the cuts directly.
