OpenAI's Codex coding tool goes mobile via ChatGPT app
Manage your development workflows remotely from your phone now.
OpenAI announced on Thursday that its AI-powered coding tool, Codex, is now integrated into the ChatGPT mobile app. The update, currently in preview, is available to all users on iOS and Android. With this move, developers can remotely monitor and manage their Codex live environments from their phones, accessing threads, reviewing outputs, approving commands, switching models, or initiating new tasks. The company emphasized that this is more than just remote control of a single task — it enables full workflow oversight.
This mobile rollout follows a series of recent enhancements to Codex. Last month, OpenAI gave Codex the ability to run autonomously in the background on desktop environments, allowing it to handle tasks without constant supervision. Earlier this month, the company also introduced a Chrome extension that lets Codex operate in live browser sessions. These updates come as OpenAI and Anthropic (with Claude Code's Remote Control feature) compete fiercely for dominance in the AI coding agent space. Claude Code has gained significant traction, but both tools remain widely used among developers and enterprises.
- Codex is now integrated into ChatGPT mobile app on iOS and Android for all plans, currently in preview.
- Users can remotely monitor live environments, review outputs, approve commands, change models, and start tasks from their phone.
- Follows recent updates: background desktop mode (last month) and a Chrome extension (this month) — competing with Anthropic's Claude Code's Remote Control.
Why It Matters
Developers gain real-time remote control of coding workflows — a decisive edge in the AI agent arms race.
