Set up the helper
About two minutes. Windows, macOS and Linux.
Checking for the helper…
The editor works on its own in your browser. The helper is optional: it runs your AI agent (Claude, Codex or Cursor) on your computer with your own account, and adds transcription, silence and scene detection, and ProRes / GIF / MP3 export. Nothing is uploaded, and it only accepts connections from this website.
1. Install the requirements
- Node.js 22 or newer — nodejs.org
- FFmpeg is included. If you already have it on your PATH, the helper uses yours.
- Chrome or Edge for the editor itself
2. Start the helper
Open a terminal and run:
The first run downloads it (a minute or two). Keep that window open while you edit, then click Connect in the editor (after the first time it connects by itself). Your browser will ask to let this site access devices on your local network — allow it, so the editor can reach the helper on your computer.
3. Connect an AI agent (any one)
| Agent | Install | Sign in |
|---|---|---|
| Claude | Your own Claude Code — the Claude desktop app, or Claude Code on its own | Sign in inside Claude Code (in the Claude app, or claude then /login). The helper finds it automatically. |
| Codex | Included with the helper | In the editor: agent menu → Codex → Sign in with ChatGPT, or add an OpenAI API key in Settings |
| Cursor | Cursor CLI — see cursor.com/docs/cli | In the editor: agent menu → Cursor → Sign in to Cursor (or cursor-agent login) |
Choose the agent from the model button at the top of the AI panel in the editor. Cursor keeps its tool settings in a .cursor/mcp.json inside your project folder. AI usage is billed by, or counted against your plan with, that provider.
Troubleshooting
- Connect can’t find the helper — make sure the terminal running the command above is still open, and that you allowed local network access (site settings → Local network access).
- Port in use — the helper uses port 5310 on
127.0.0.1. Close other copies of the helper or the desktop app. - Media offline — media stays on the computer (and browser) where you imported it. On another computer, re-import the files.
