Codex (OpenAI's version)

Codex is OpenAI's version of Claude Code. If you already pay for ChatGPT Plus, you can use it instead. It works in a folder on your computer, builds files, and fixes them when you ask.

The guides on this site use Claude Code, so the steps and videos match that. Codex works the same way. Only the install and login are different:

1. Install Codex
2. Your first project with Codex

Heads-up: Codex in the ChatGPT website is a different product. These pages are for the one on your computer.
