3 Free CapCut Alternatives That Edit With ChatGPT or Claude

CapCut just put an AI video editor inside ChatGPT: you describe an idea or upload clips, and it builds an editable draft. Three free, open-source editors already do the same thing, and they work with Claude as well as ChatGPT.

OpenChatCut gives you a real timeline with an AI agent that cuts your pauses and adds captions. OpenFilm builds the video while you watch, with no account of its own. HyperFrames, from HeyGen, has your AI make titles and motion graphics from one sentence.

The AI doing the edit is the ChatGPT or Claude plan you already pay for, not a new subscription.

Below is what each one does, and how to plug in the AI you already have.

Which free CapCut alternatives edit with AI?

OpenChatCut, OpenFilm and HyperFrames are free, open-source editors where an AI agent does the edit and every change stays yours to adjust by hand. CapCut's own version runs in the ChatGPT desktop app, and as of 3 November CapCut's page says it's available outside the US, with US availability coming soon.

OpenChatCut: a real timeline with an AI agent built in

OpenChatCut is open source (AGPL-3.0), with almost 3,000 stars on GitHub. It gives you a real multi-track timeline, like CapCut's, with an AI agent built in that cuts your pauses and adds captions that stay off your face.

Every edit lands on real tracks and clips, so you can trim the rest by hand or undo it.

OpenFilm: tell it what you want and watch it build

OpenFilm is MIT licensed, and it passed 4,000 stars on GitHub in its first month. Its desktop app is an editor with a chat beside it: you say what you want, watch the video build on the timeline, then change anything by hand or by asking.

Making, editing and exporting needs no account. Captions do need a transcription key of your own, and Groq's free tier works.

HyperFrames: titles and motion graphics from one sentence

HyperFrames is HeyGen's open-source video framework (Apache-2.0), with over 78,000 stars on GitHub. Think of it as CapCut's text and motion effects, except your AI builds them from one sentence, and you can preview and change them in its Studio.

It has no per-render fees, so you export as many as you like. It needs a coding agent to make anything: Claude Code, Codex or Cursor.

How do you plug in the AI you already have?

Each editor runs on AI you may already pay for: your ChatGPT plan through OpenAI's Codex, or your Claude plan through Claude Code.

OpenChatCut. Download it for Mac, Windows or Linux from its GitHub Releases page. The Mac builds aren't signed yet, so your Mac may ask you to approve it the first time you open it.

To run its agent on your ChatGPT plan, install OpenAI's Codex CLI (version 0.146.0 or newer). Then in OpenChatCut, open Settings, Agent model, OpenAI · Codex, sign in with ChatGPT, and pick Codex in the chat's model picker. Drop in a raw clip, ask the agent to cut the pauses and add captions, then trim the rest by hand.

On Claude, OpenChatCut doesn't take a Claude sign-in, so you connect Claude Code to it instead. With OpenChatCut open, go to Settings, then MCP. The app shows this command there with your token in place of <token>, so copy it and run it in your terminal:

claude mcp add --transport http -H "Authorization: Bearer <token>" openchatcut http://localhost:5199/api/external-mcp/mcp

By default, Claude Code's edits arrive as a draft you approve in OpenChatCut, not straight onto your timeline.

OpenFilm. Download the desktop app for Mac or Windows from openfilm.dev. It comes with the video tools it needs built in. Its chat runs a coding agent you already have: in Settings, then Agents, pick Claude Code for your Claude plan or Codex for your ChatGPT plan, and sign in if it asks.

For captions, add a free Groq API key in Studio under Settings, Providers. Groq's free tier takes files up to 25 MB. Then ask for a 20-second video and fix it in Studio while it builds.

HyperFrames. You need a coding agent first: Claude Code, Codex or Cursor, plus Node.js 22 or newer and FFmpeg. Then run this once:

Ask your agent for a title animation in one sentence, and export it free.
