Koi AI - AI Video Studio
From script to a short film
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
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.
Photo or prompt to video
Bring a still to life or start from a blank line. Animate any photo with natural motion, or describe a shot and let Koi build it — sketch-style or fully cinematic, no camera needed. Smart Ref locks the look to a reference image; Frames pins keyframes for precise motion.
Restyle footage you already have
Already shot something? Recolor it, restage it, repaint the world inside it — anime, oil, neon-noir, stop-motion. Koi remixes existing clips into looks you couldn't film.
Fast, flexible, yours
Renders land in the time it takes to write a caption. Tune aspect ratio, length, and reference strength so every clip stays yours, not the model's.
A whole crew in your pocket: you bring the idea, Koi handles the shoot — from a single shot to a full short film.
