You don’t need a big app idea to try Codex. A messy Downloads folder is enough.

In this beginner walkthrough, you’ll ask ChatGPT to write a prompt in plain language, then paste it into Codex in Terminal to build a simple file organizer.

You’ll see how to:

  • Ask ChatGPT for a detailed Codex prompt
  • Paste the prompt into Codex
  • Organize files into folders without deleting them
  • Log every move, adjust the rules, and undo changes

The file names and folder contents shown are fictional examples. Your first version doesn’t have to be perfect; you can improve it with follow-up prompts.
