Work with Codex from anywhere

OpenAI has rolled out mobile support for Codex by integrating it into the ChatGPT iOS and Android apps, allowing paid-subscriber users to remotely view and manage development workflows and inspect Codex's live runtime environments on any device. The company announced the preview-stage feature on Thursday; it brings its year-old code-generation and development tool to phones, aiming to extend developer productivity and oversight outside desktop environments. Availability to all paid mobile subscribers signals OpenAI's push to make advanced coding assistance more accessible and to compete in the AI coding tools market. The change matters for developers, teams, and tooling ecosystems that rely on cloud-based AI coding assistants.

OpenAI has added Codex — its desktop agent that can write code and operate apps on a user’s computer — to the ChatGPT mobile app, enabling users to control Codex running on macOS or Windows from iOS and Android. The integration lets phones send commands, review outputs, approve actions, and receive real-time updates (screenshots, terminal output, diffs, test results) while keeping files, credentials, and permissions on the host machine. The move follows pressure from competitors like Anthropic’s Claude Code and comes as OpenAI narrows focus toward enterprise and desktop ‘superapp’ ambitions. The Codex mobile preview is rolling out now to all ChatGPT plans, including the free and Go tiers.
