Codex runs inside the Kino desktop app. Sign in once with the ChatGPT account you already have, and the agent works on the project you have open: it searches your footage, edits the timeline, writes motion graphics, and exports video. Kino doesn’t meter these messages; they run on your ChatGPT plan.

​
Set up

  1. In the desktop app, open chat with Cmd+L. Your first chat asks you to choose an agent — hit Continue with Codex. After that, the agent picker (Cmd+/) switches agents anytime.
  2. Sign in when prompted. Kino opens ChatGPT’s sign-in page in your browser, and the app connects on its own once you finish there.
Codex is available in the desktop app on macOS, Windows, and Linux. Kino downloads and manages the Codex executable, so there is nothing to install separately. In the browser, chat with Kino works as before.

​
What it can do

The agent has the same project tools as Kino’s own agent: transcript and visual search, timeline edits, project code, bins, and export. It also brings its own abilities, like running shell commands and reading and writing files, and those go through your approvals.

​
Control how much it does

Choose the model per conversation: GPT-6 Astra for the hardest work, GPT-6 Sol for everyday demanding work, GPT-6 Luna when you want answers fast. Set effort to trade thoroughness against speed and usage, and switch speed from Standard to Fast for 1.5× speed at higher usage. Three permission levels set how independently the agent works: approve each action, auto-approve edits, or skip approvals entirely. Auto is the default. It runs sandboxed work unattended and only asks when something needs to reach outside the project. For bigger requests, press Shift+Tab to toggle Plan mode. The agent reads without writing and proposes a plan you review before it touches the timeline.

​
Long sessions, without the mess

A live strip shows what the agent is running. Fork a session to try a different direction, or rewind it to an earlier point and continue from there.

​
Codex outside the app

Codex can also drive your open project from a terminal over Kino’s MCP server, with the same project tools. See Getting Started with MCP to connect it, and Edit with your agent for a worked example.
