AI video editor for Claude Code and Codex

Last updated: November 10, 2026

Yes, a video editor can run on your own Claude or ChatGPT subscription. SpaceCut is a video editor for Mac and Windows with an AI agent inside. You sign in to Claude Code or Codex once, from the app, and the agent edits your footage on a real timeline. SpaceCut sells no AI credits and asks for no API key.

Which plans work

Your AI	The plan you need	What SpaceCut connects to
Claude	Claude Pro or Max	Claude Code
ChatGPT	ChatGPT Plus or Pro	Codex

Claude Code is not part of Claude’s free plan. We checked both lists on November 10, 2026 against Anthropic’s pricing page and OpenAI’s Codex pricing page. Plans change: read theirs before you buy.

What you pay, and to whom

Using your own subscription does not mean free. There are two bills, and no third one.

SpaceCut: a monthly, yearly or lifetime license. See the prices.
Your AI plan: the one you already have, paid to Anthropic or OpenAI. SpaceCut never resells AI usage and adds no markup.

Your plan’s limits still apply. A long edit uses your quota the way any other Claude Code or Codex session does.

What the agent does

You ask in plain words, or you draw on the frame and leave notes. The agent then works on the timeline:

cuts retakes, false starts and stutters, on the silence between words;
builds animations for your video (titles, stats, lower thirds, transitions) in your fonts and colors;
adds captions in your style, zooms and color;
turns a long video into shorts, each one its own edit;
copies the pacing and look of a reference video you give it.

Every change is a normal edit on a normal timeline. You can undo it, move it, or change any setting of an animation yourself, without asking again. When you’re done, render an MP4 or export the sequence to Premiere Pro, DaVinci Resolve or Final Cut Pro.

The SpaceCut editor: a video with captions and an animated lower third, a timeline with three video tracks and one audio track, and the settings of the selected animation on the right.

What goes to the AI, and what stays on your computer

Stays on your computer: your video files, your projects and your transcripts. Transcription runs on your computer.
Goes to the AI you connected: your requests, and what the agent needs to see to do the job (transcript excerpts, still frames). It goes straight from your computer to Anthropic or OpenAI, under your own account and their terms.

The agent needs an internet connection, because Claude Code and Codex run online. Without one, you can still change your timeline by hand, adjust the settings of an animation and export.

Approach	Runs on your subscription	A timeline you edit by hand	Animations made for your video	Opens in Premiere, DaVinci or Final Cut
An AI editor with its own credits or plan	No, you buy theirs	Depends on the tool	Depends on the tool	Depends on the tool
Claude or ChatGPT with an FFmpeg connector	Yes	No	No	No, it renders files

Questions

Do I need an API key? No. You sign in to Claude Code or Codex with your usual account, from a button in SpaceCut.

Does it work with the free plan of Claude or ChatGPT? Not with Claude’s free plan, which does not include Claude Code. For ChatGPT, we support Plus and Pro.

Is SpaceCut an MCP server or a plugin for Claude? No. SpaceCut is a full video editor with the agent inside it. You don’t add it to Claude Desktop or ChatGPT: you open SpaceCut, and your Claude Code or Codex plan powers the agent there.

Do I need to know how to code or use a terminal? No. You talk to the agent in a chat panel next to the timeline.

Which computers does it run on? Macs with Apple silicon (M1 or later), and PCs with Windows 10 or 11 (64-bit).
