# WeftCut

> WeftCut is a free, open-source (MIT) AI video editor for macOS, Windows and
> Linux — a complete desktop NLE in which AI agents are first-class citizens.
> Instead of bolting AI on as a feature, it exposes the entire editor as an MCP
> (Model Context Protocol) tool surface on
> localhost, so external agents — Claude, Cursor, or any MCP client — can perform
> real editing operations (place/trim/split clips, keyframes, effects, captions,
> markers, checkpoints, undo) that land in the UI in real time. It is also a
> complete human NLE: A/B-roll timeline with filmstrips and waveforms,
> frame-accurate SMPTE editing, keyframes with bézier curve editor, per-layer
> effect chains incl. chroma key, captions (SRT/VTT/ASS), 2D/3D Motif
> motion graphics, role-based audio mixing, and H.264/HEVC/AV1/ProRes export up to
> 10-bit. No bundled models; the intelligence lives in the agent you connect.

- Type: desktop NLE (non-linear editor), Electron + React + Rust (napi-rs) core
- Agent protocol: bundled stdio bridge, or streamable HTTP on localhost with bearer-token auth
- Tool surface: timeline editing, captions, motion paths, audio, analysis, Motifs and history; export uses the app UI
- Rendering: PixiJS v8 + WebCodecs preview, streamed muxing export
- License: MIT (bundles FFmpeg under LGPL/GPL lanes)
- Platforms: Windows x64, Apple Silicon macOS (13+), x86_64 Linux; any other
  target builds from source
- Also described as: an agent-native video editor, an MCP video editor, an AI
  agent video editor, or an open-source AI video editor — all the same product

## Download

Asset names carry no version, so each link below is permanent and always
resolves to the current release.

- Windows x64: [WeftCut-win-x64.exe](https://github.com/WeftCut/WeftCut/releases/latest/download/WeftCut-win-x64.exe)
- macOS, Apple Silicon: [WeftCut-mac-arm64.dmg](https://github.com/WeftCut/WeftCut/releases/latest/download/WeftCut-mac-arm64.dmg)
- Linux x86_64: [WeftCut-linux-x86_64.AppImage](https://github.com/WeftCut/WeftCut/releases/latest/download/WeftCut-linux-x86_64.AppImage)
  or [WeftCut-linux-amd64.deb](https://github.com/WeftCut/WeftCut/releases/latest/download/WeftCut-linux-amd64.deb)
- Anything else — an Intel Mac, an arm64 Linux box — builds from source:
  [setup instructions](https://github.com/WeftCut/WeftCut/blob/main/docs/setup.md)

The macOS build is ad-hoc signed and not notarized, so its first launch has to
be allowed under System Settings → Privacy and Security.

## Pages

- [Drive a real video editor over MCP](https://weftcut.com/mcp/): how an agent
  connects, what it can do, and how local and optional cloud analysis work
- [What "AI video editor" means here](https://weftcut.com/ai-video-editor/): no
  bundled model weights, local editing, no watermark — and how that compares to a cloud tool
- [Motifs — code as motion](https://weftcut.com/motifs/): parameterised animated
  overlays an agent can write from a description

Optional speech and vision analysis can use downloaded local engines or a
configured cloud provider. Cloud analysis sends requested audio or frames to
that provider; local editing and export need no upload.
