Summary
OpenAI’s Codex desktop app can now be controlled remotely from the ChatGPT iOS app, and this video walks through everything you need to know to set it up and actually get value from it. Riley Brown covers the full pairing process—ensuring both apps are on their latest versions, connecting over the same Wi-Fi network, and authorizing the link so chats stay in sync between desktop and mobile.
Beyond setup, the video surfaces a key limitation: apps vibe-coded inside Codex run on localhost, meaning links sent to your phone simply won’t open. Brown’s solution is a custom Codex skill he calls “YOLO mode,” which auto-deploys any locally running project to a public URL every time changes are saved. With that in place, Codex Mobile becomes a genuine remote vibe-coding environment—you can prompt by voice, monitor running agents via live notifications, and open finished apps directly inside the ChatGPT mobile interface.
The video also maps out which ChatGPT plugin types work today (documents, spreadsheets, browser, computer use via the @ symbol) versus what’s still missing (slash-triggered skills, though natural-language skill invocation still functions). It’s a practical, current snapshot of Codex Mobile’s real-world capabilities and workarounds as of its preview launch on May 15, 2026.
