Koi is an AI video studio that fits in your pocket — and unlike most, it doesn't stop at a single clip. Its signature move: describe a scene and Koi turns it into a storyboard of connected shots, then renders them into one continuous short film with a beginning, middle, and end. That's where Koi starts — here's everything else it does. Direct your own short film Type a scene in plain words. Koi breaks it into multiple shots — each with its own characters and beat — as an editable storyboard. Rewrite any shot, see the full cost up front, then generate the whole sequence and watch it stitch into one continuous video, longer than any single AI clip. Tap a trend, get a look A constantly refreshed wall of viral presets — dance loops, transformations, stylized portraits. Pick one, drop in a photo, and your clip is ready to post.
