Edit video with the AI you already use

Connect Null Studio to Claude, Codex, or Cursor. Ask for the cut in your chat, and your assistant runs the edit in the timeline you have open. Every step shows up in Null and can be undone.

Tighten my podcast clip: cut the pauses, add captions 3 words at a time, and put a “Follow for part 2” button at the end.
  1. cut_dead_air7 pauses · 1:12 → 0:58
  2. set_captions41 cards · 3 words
  3. add_motionCTA at 0:54
  4. get_framechecked the ending
Done. The clip is 14 seconds shorter, captions are on, and the button lands in the last four seconds. I checked the final frame and it isn’t covering the captions. Want me to export it?
HOW IT WORKS

Your AI talks. Null edits.

MCP is an open standard that lets AI apps use outside tools. Null Studio ships an MCP server, so your assistant can read your project and change it, one visible step at a time.

  1. You ask your AI

    Type the edit in Claude, Codex, or Cursor, the way you would ask an editor.

    “cut the pauses, add captions”
  2. Null MCP runs the tools

    A small server inside Null Studio, on your computer. It turns requests into 17 editing tools.

    127.0.0.1:4350/mcp
  3. Your timeline changes

    Cuts, captions, and motion land in the project you have open. You can see and undo each one.

  • No API keys. Your AI app uses the account you already pay for.
  • Footage stays on your computer.
  • Every call is one undo step. Ctrl+Z works.

Questions about MCP

Which AI apps work?

Claude Code, Claude Desktop, Codex, and Cursor, plus any other MCP client that can reach a local server over Streamable HTTP or stdio.

Do I need an API key?

No. Your AI app uses the account you already have, and Null never sees your credentials. Null Studio only accepts connections from your own computer.

Does my footage get uploaded?

No. Your video stays on your computer. Your AI sees the transcript, project details, and any frames it asks for, the same way it sees anything else you share in the chat.

Can it wreck my edit?

Every tool call is one step in Null’s undo history and shows in the agent panel as it happens. Press Ctrl+Z, or ask your AI to undo.
