Short-form videos, made by your coding agent
Cutfac is a Mac app for solo developers who market their own app. Claude Code or Codex makes your TikToks, Reels and Shorts. When something is off, you select it, box it and say what to change.
How an edit works
You never learn a video editor. You mark the moment and describe the change.
- 1
Select the moment
Drag across the timeline, or press I and O at the playhead. The range is what the agent will change.
- 2
Box what's wrong
Drag a box over a caption, a logo or a face. It's optional; the range alone is often enough.
- 3
Say it plainly
Type what you want, like “make this caption shorter” or “get to the demo sooner”, and press Enter.
- 4
Compare, then keep
The agent gets a clip of the range, the frame with your box drawn on it, the timecodes and the original file. Compare before and after, then keep the edit or restore the previous version.
From a link to a finished video
Learn
Paste a link to your site, your store page or a video you like, or pick a folder. Cutfac takes a first look, with scene cuts, hook frames and a contact sheet for a video, and your agent reads the rest. Every video after that knows your product.
Templates
What works becomes a template with hook rules, beats, length and checks, so your agent doesn't start from a blank page. A post, a repo or an Agent Skill can become one too.
Self-review
Your agent writes a brief and a shot list for you to okay before it renders. Then it looks at the frames it made, every cut included, and fixes the biggest problems first.
Board
Every video moves from drafting to review to done on one board, with timecoded feedback and upload checks along the way.
Runs on the agent you already pay for
Cutfac starts Claude Code or Codex on your Mac, one session per video, and shows each step as it works. It uses your own account and plan, so there's no second AI bill.
No agent set up? Every request has a Copy prompt button with the timecodes and file paths, ready to paste into any assistant.
Plain files on your Mac
- Workspaces are plain folders and YAML you can open, diff and back up.
- Videos are processed on your Mac with ffmpeg. Nothing is uploaded to us.
- If you stop paying, the app and your files keep working.

Stop editing. Start pointing.
Your agent makes the cut. You mark what's wrong and say what you want instead.
