Read the full comparison
| Option | How it works | Best for | Watch out for |
|---|---|---|---|
| Letaido AI agent | Leta collects the input from your other apps, writes Codex a brief and reports back in the chat once Codex is done. | Marketers turning Ahrefs, Search Console, Linear or Google Docs input into site changes. | No event trigger, so each job begins in a chat. Codex reaches your site's code through a GitHub connection. |
| Codex app, CLI and IDE extension | Sign in with ChatGPT or an API key, then describe the change. Codex inspects the code on your machine, makes edits and runs tools. MCP servers and plugins add outside data. | Developers working in a checked out repo. | Needs a ChatGPT sign in or an OpenAI API key. Desktop scheduled tasks that use local files need the computer on and the app running. |
| Codex Cloud | Tasks run in a cloud environment with a repo from your connected GitHub or GitLab account, and keep working while your computer sleeps. | Longer coding tasks you review and turn into a pull request later. | Needs ChatGPT sign in. Repo work needs a connected GitHub or GitLab account and an environment for it. |
| Codex in Slack and Linear | Mention @ChatGPT in Slack, or assign a Linear issue to Codex. Repo work runs as a Codex Cloud task and the result comes back to the thread. | Teams that already file website requests in Slack or Linear. | Codex in Linear needs a paid ChatGPT plan. In Slack, an admin sets up the app and a shared cloud environment. |
| Codex GitHub Action and SDK | A GitHub workflow runs Codex on a GitHub runner on repo events with a saved prompt, or your developers control Codex from their own code. | Engineering teams building Codex into CI or internal tools. | The Action needs an OpenAI API key as a repository secret. An SDK program keeps running without your laptop only on a server or runner you host. |

Frequently asked
How do I connect Codex to Letaido? +
Add Codex from the apps list in Letaido. No key is involved, because Codex runs inside Letaido. Choose a default model if you want one, and connect GitHub so Codex has your site's code.
Do I need a ChatGPT plan or an OpenAI API key? +
No. Codex in Letaido uses Letaido's AI access, and what it uses is billed with the rest of Leta's work.
Is there a Codex MCP server? +
On its own, Codex can add outside data through MCP servers and plugins. Letaido is not an MCP server. Inside Letaido, Codex calls Letaido's own connectors and asks you through the usual approval cards.
Does Codex keep working in the background? +
Yes. A task can run anywhere from a few minutes to a few hours. Carry on with other work, and Leta writes in the chat once Codex finishes.
Will Codex change my live site? +
Every job here ends with a pushed branch or a draft pull request. None of them merges. Look over what Codex proposes in GitHub first.
How is Letaido different from Codex Cloud? +
Codex Cloud runs coding tasks in OpenAI's cloud with your ChatGPT sign in, and repo work needs an environment set up for it. With Letaido, one request gets Leta to read Ahrefs, Search Console or Linear first, so Codex starts with the right data.
What do I approve before Codex starts? +
Allow all read operations once per app; approve each kind of write once.
Turn marketing requests into code with Codex
