OpenAI brings Codex desktop AI control to ChatGPT mobile apps
OpenAI is rolling out mobile access to Codex, its desktop AI tool that can write code and control applications on users' computers. The feature allows users to control Codex on their desktop from the ChatGPT iOS and Android apps, with real-time updates flowing back to mobile devices.
OpenAI brings Codex desktop AI control to ChatGPT mobile apps
OpenAI is rolling out mobile access to Codex, its desktop AI tool that can write code and control applications on users' computers. The feature launches today as a preview on iOS and Android across all ChatGPT subscription tiers, including the free plan.
How it works
Users can now control Codex running on their desktop computer directly from their phone. According to OpenAI's blog post, the mobile interface allows users to "work across all of your threads, review outputs, approve commands, change models, or start something new" in Codex.
The architecture keeps files, credentials, permissions, and local setup on the desktop machine where Codex operates. Updates—including screenshots, terminal output, diffs, test results, and command approvals—sync to the mobile device in real time.
Competitive context
The move follows Anthropic's Claude Code gaining significant market traction. OpenAI has reportedly accelerated its desktop AI efforts in response, cutting what the company called "side quests" like the Sora video-generation tool to focus on enterprise growth and desktop capabilities.
OpenAI recently shipped a major Codex update enabling macOS app control, positioning the tool as part of its broader desktop "superapp" strategy.
Availability
The mobile Codex feature is available now in preview on iOS and Android. OpenAI confirmed access extends to all ChatGPT plans, including the free tier and the Go subscription tier.
What this means
Mobile control of desktop AI agents represents a shift toward more flexible deployment models. By separating the control interface from the execution environment, OpenAI addresses security concerns around credentials and file access while enabling remote workflow management. The inclusion of free-tier access suggests OpenAI is prioritizing user adoption over immediate monetization as competition in AI coding assistants intensifies.
