Edit Video With an AI Co-Editor on Your Mac
Palmier Pro is a free Mac video editor where an AI agent and you edit the same timeline at the same time — no login, no subscription.
A video editor that has a second pair of hands
Imagine sitting at a video editing table with a very fast, very patient collaborator. You trim a clip, they reorder the next sequence. You tell them "cut the first thirty seconds," and the timeline just changes — right in front of you.
That's the idea behind Palmier Pro. It's a free, open-source video editor for Mac, and it went from zero to the most-starred project on GitHub in a matter of days. Not because it does something flashy. Because it does something genuinely different.
Most AI video tools work in one of two ways: they let you edit by editing a text transcript (like Descript), or they generate clips from a prompt (like Runway). Neither of them lets an AI actually operate the timeline — the thing with all your clips, cuts, and transitions on it.
Palmier Pro does. You connect an AI assistant — Claude, Codex, or Cursor — and it can add clips, trim footage, reorder scenes, all while you're doing the same. The editor and the AI share the same workspace.
For a small business owner making product videos, event recaps, or social content, this matters. You don't need a dedicated editor. You work alongside something that can do the mechanical, time-consuming parts.
No login. No monthly fee. Just download it on a Mac and start.
Words worth knowing
Open-source — The code is public and free. Anyone can use it, inspect it, or improve it. Think of it like a recipe that's been published for everyone.
Timeline — In video editing, the timeline is the horizontal strip where your clips sit in order. It's where you cut, move, and arrange everything.
MCP server — A small bridge that lets an AI assistant talk to other software — in this case, the video editor. It starts automatically when you open the app.
AI agent — An AI that doesn't just answer questions but actually does things: clicks buttons, moves files, edits timelines.
If you've been putting off video because editing takes too long, this is worth downloading and spending twenty minutes with: https://github.com/palmier-io/palmier-pro
