KoraCut

Why KoraCut

Most editors bolt an AI button onto a closed app. KoraCut goes the other way: it is a complete desktop editor (built on the solid foundations of Kdenlive and MLT) where every action is also a tool an agent can call. You keep your account, your model and your files. Your rushes never leave your computer.

• One window, seven modules: Editing, Color, Audio, VFX, Photo, Illustration, Export, with Motion design inside the timeline.
• Agents that edit for real: 126 tools (cut, trim, place, grade, mix, subtitle, animate, export), each call is one step in the undo history. You watch the agent work in the timeline.
• Bring your own agent: 15 command line agents are supported out of the box, from Claude Code, Codex CLI and Gemini CLI to OpenCode, Aider and goose. KoraCut writes their instructions, connects them and launches them in a window that stays open even if the app closes.
• MCP server included: koracut-ctl mcp exposes KoraCut to any Model Context Protocol client, no Node.js needed.
• Made for modest machines first: light proxy copies, adaptive preview, a machine profile chosen at first launch, so editing stays smooth on 4 cores and 8 GB.

What you can do today

Module	What it does
Editing	Multi-sequence timeline, sequences side by side, DaVinci-style shortcuts, auto-cut of silences and filler words, script panel linked to the timeline, subtitles
Color	Node-based grading (wheels, curves, qualifier, windows, LUT, color space transform), the same grade in preview and in the export
Audio	Mixer, loudness normalization to platform targets, voice cleanup (RNNoise), music ducking, voice effects, AI voice-over
Motion design	HTML + GSAP compositions (HyperFrames) rendered straight into the timeline, animated titles and transitions
VFX	Stabilization, subject cut-out to pass elements behind a person (macOS), privacy blur that follows a phone or a name
Export	A delivery page with 25 presets (YouTube, Shorts, TikTok, Instagram Reels, LinkedIn, WhatsApp status, ProRes masters…) and a render queue
Photo, Illustration	In progress

Edit with your AI agent

1. Open or save your project, then choose Edit with an Agent.
2. Pick your agent (Claude Code by default). KoraCut writes its instructions in the project folder, connects it to the running app and opens it in its own terminal window.
3. Ask in plain words: "Cut the silences of the interview, put the music under it at -18 LUFS, and add a title at the start."
4. Every change lands in the timeline. One Undo takes back a whole turn of the agent.

From any terminal, the same doors are open:

koracut-ctl timeline etat niveau=resume          # read the timeline
koracut-ctl timeline outil nom=couper_clip args='{"clip_id": 21, "position": "00:00:04:00"}'
koracut-ctl mcp                                   # MCP server over stdio

Agents never touch your media with ffmpeg or a script behind your back: they edit inside KoraCut, through its tools, or they stop and say what is missing.
