I’d like to suggest a feature that could significantly improve the developer experience within ChatGPT: the ability to directly interact with Codex from the mobile ChatGPT app.
The idea would be to integrate a dedicated interface where users can connect their codebase and collaborate with Codex in a more structured way. This could include two distinct modes:
Ask Mode
A conversational mode where users can ask questions about their code, get explanations, explore improvements, or brainstorm architectural changes. This would essentially act as a thinking partner—helping analyze code, suggest refactors, and reason about design decisions.
Patch Mode
A more action-oriented mode where Codex can propose concrete code changes (patches/diffs) based on user requests. These changes wouldn’t be applied automatically but would instead be reviewed and approved by the user before integration into the codebase. This would make it safer and more controlled, while still benefiting from automation.
Having this available directly in the mobile app would make it much easier to iterate on ideas, review code on the go, and collaborate with AI in a seamless way—without needing to switch environments.
I believe this kind of dual-mode interaction (thinking + acting) could unlock a much more powerful workflow for developers.
Hey — yeah, this is a really solid idea. Totally get the appeal of having a “think + act” flow right from mobile.
What’s happening today, pieces of this exist (code chat, suggestions, diffs in some workflows), but they’re not unified or mobile-first. The gap is exactly what you called out: structured interaction with a repo + clear separation between exploring ideas and proposing changes.
What to try (for now):
Use chat for “Ask mode” style reasoning and paste snippets or files when needed
For “Patch mode”, a few folks are generating diffs in chat and applying them manually in their repo
If you’re using GitHub, pairing ChatGPT with PR reviews gets you close to that review loop
This kind of dual-mode setup comes up a lot, especially the approval step before applying changes. Makes sense.
If you have a specific mobile workflow in mind (like reviewing PRs, editing files, or just brainstorming), would love to hear that. Helps sharpen what this could look like.
What I’m imagining is something along these lines: if I connect Codex to GitHub and grant it the right permissions, I could access Codex directly from within the app, either through a dedicated entry point or just a simple button.
Once inside, there would be two distinct modes: “Ask” and “Edit.” The Ask mode would be more about thinking and exploring. For example, if I’m in the tram, the metro, or the bus and I have an idea, I could quickly explore how to implement it or figure out a solution to something I’m stuck on, just to make things clearer in my head without touching the code yet.
Then, when I’m ready to move forward, I’d switch to Edit mode. At that point, Codex would directly apply changes to the repository on GitHub, create a new branch, and push everything so it’s ready for review and merging.
So the idea is really to have a smooth transition from thinking to acting, all in one place, in a way that works well even on mobile.
