Codex is going mobile. The coding tool — which OpenAI launched approximately a year ago — has now been integrated into the ChatGPT app, allowing users to monitor and manage their development workflows remotely.
The new function allows users to see their Codex live environments in any devices where it is running. The company announced the changes Thursday; the update, which is currently in preview, is now available to all plans on iOS and Android.
“This is more than the ability to remotely control a single task or dispatch new tasks to your computer,” OpenAI said in a statement. “From your phone, you can work across all of your threads, review outputs, approve commands, change models, or start something new.”
Last month, OpenAI also gave Codex the ability to run in the background in desktop environments — empowering the tool to take care of various tasks autonomously. Earlier this month, the company also introduced a Chrome extension that allows the agent to work in live browser sessions.
In February, Anthropic released a similar feature — Remote Control — which allows users to remotely monitor Claude Code’s work from afar.
The flurry of feature releases from both OpenAI and Anthropic speaks to the tense competition between the two over whose agentic coding tool will become the most widely used. Over the past year, Anthropic’s Claude Code has gained in popularity among businesses and tech professionals alike, although both tools continue to be widely used.
