Add native Markdown preview in the Codex macOS app

Please add a built-in Markdown preview mode that renders headers, lists, tables, code blocks, links, and checkboxes with readable styling.

I want to be able to read all my AI agent generated plans easily before execution or during review

Hey @AndresTheDesigner, thanks for bringing this to our attention. A couple quick questions so we can pass along the right details:

1. What are you ultimately trying to accomplish, in your own words?

2. What do you do today instead, and what about that isn’t working for you?

3. If we solved this perfectly, what would be different for you or your team?

Appreciate any extra details you can share. They’ll help us reproduce it and get it in front of the right folks.

Let me see if I can give this a try, by actually reading - instead of filling the forum with action-less bot-based form letters.

Already Answered

  1. Ultimately: Preview the AI-created plans in the Codex MacOS app, but without it being unformatted markdown source.

  2. Presently: Suffer through text that leaks underlying markdown in .MD files, such as ## [ ] Using `markdown-it` in **closed-source software**

  3. If Solved: Could then read AI agent-generated plans easily, without friction.


or… let’s show how you could have employed all the information already given – AI internal use – instead of simply a time waste asking a new forum member to create more text that won’t be read.

AI *assistant* Output Task: fill out the form questionnaire automatically from the *Input* OpenAI developer forum posting. ---

# **Questionnaire** - 1. What are you ultimately trying to accomplish, in your own words?; 2. What do you do today instead, and what about that isn’t working for you?; 3. If we solved this perfectly, what would be different for you or your team?

The most shameless thing shown in your questionnaire is implying that someone’s words aren’t their own, while you break OpenAI’s policy on undisclosed use of AI pretending to be human. (although it seems the AI would understand).
