How to save, export and share a chat from Codex

Codex is a powerful AI coding tool. While Codex is great for interactive development sessions, it doesn’t have a built-in way to export chat history or share conversations. If you’ve ever wanted to export a Codex chat, save a session for later reference, or share an AI-assisted coding session with a teammate — this guide is for you.

Using Cooontext, you can export any Codex conversation in under 30 seconds and share it with coworkers, followers, or friends.

Why Export Your Codex Chat?

Before diving into the steps, here’s why developers commonly need to export Codex sessions:

  • Share Codex chats with teammates — pass along a useful debugging session or architecture discussion without copy-pasting walls of text.
  • Export Codex chat history for documentation or postmortems.
  • Save context from a long coding session to revisit later.
  • Publish Codex conversations to your blog or social media to show your workflow.
  • Export prompts you’ve refined over time to reuse or share with others.

Codex doesn’t natively support any built-in export command, which is why a dedicated tool like Cooontext fills the gap.
