Yes — free and open source under the MIT license. FFmpeg is bundled under its own LGPL/GPL terms.

Which agents can I connect?

Any MCP client — Claude Desktop, Cursor, Codex, or your own. Copy one snippet from Settings → Agent, paste it into your client, and the agent can edit alongside you. WeftCut bundles no AI models — your agent is the intelligence.

Does it work without an agent?

Yes — it's a complete editor on its own: timeline, keyframes, effects, captions, motifs, audio mixing, and export up to 10-bit AV1 and ProRes.

Where does the AI run?

In your agent, not in the app — WeftCut ships no models. Optional analysis like transcription and scene description runs locally on your machine.

What platforms does it run on?

macOS, Windows and Linux — one desktop app, same feature set everywhere. The ready-made builds cover Windows x64, Apple Silicon Macs and x86_64 Linux; every other target builds from source.

Scene 01The differentiator

Native by design. For agents.

WeftCut opens the whole editor to your agent over standard MCP — everything you can do, the agent can do.

CONNECT
Settings → Agent, copy, paste — Claude, Cursor, or any MCP client connects in a minute. A Skill ships with it, giving your agent the full picture of what WeftCut can do. All local; nothing uploaded.
THE CRAFT
The full editing vocabulary is on the table: trim, split, transitions, keyframes, effects, captions, markers, undo.
CONTROL
Edits land live under a checkpoint — review the change feed, or undo and take back the wheel anytime.
INSIGHT
Optional local analysis lets the agent look before it cuts: shots, silences, transcription, scene description.

things you can sayplain words → real edits

“Cut the silences out of this interview and tighten the pauses.”
“Split this take at every shot change and label the scenes.”
“Restyle every caption — larger, with a soft shadow.”

Scene 02Code as motion

Your agent knows code. With Motifs, it knows motion.

Describe your idea. Let your agent turn it into a Motif — where code becomes motion and every look stays reusable.

WHAT YOU SEE IS WHAT YOU GET — RENDERED INSTANTLY

“Add a title, lower third, and countdown to this scene.” ACTUAL EXPORT

Describe

Whether it’s a title, lower third, callout, or an entirely new design, tell your agent what you want.

Preview

Your agent turns the idea into a Motif you can play on the timeline.

Polish

Refine it in context and reuse the finished look in your next edit.

Scene 03The human cut

Full control for humans.
Full access for agents.

You keep the precision and control of a serious desktop editor. Your agent gets access to the same tools, while every change remains visible on your timeline.
