OpenAI has released a new way to interact with its Codex agent from your smartphone. An update to the ChatGPT mobile app brings remote access to Codex for Mac to iPhone, iPad, and Android devices. This integration allows users to stay connected to their automated coding and task-completion workflows even when they are away from their main computer.
Remote Access Through the ChatGPT App
While Codex remains a standalone application on the Mac, OpenAI has chosen to embed the remote connectivity features inside the well-established ChatGPT mobile app rather than creating a separate Codex mobile client. This decision leverages the existing user base and infrastructure of ChatGPT, simplifying the setup process for millions of users who already have the app installed.
“Codex is now in the ChatGPT mobile app so you can stay in the loop from anywhere while Codex gets work done across your laptops, devboxes, or remote environments,” OpenAI announced today. The company emphasizes that the mobile experience is designed for approving ongoing tasks, reviewing what Codex has discovered, and initiating new prompts without needing to be physically present at the computer.
As AI agents take on increasingly longer-running and complex work, a new rhythm for collaboration is emerging. To keep work moving efficiently, users need the ability to quickly answer questions, review findings, change direction, approve the next step, or add a new idea – all from a mobile device. OpenAI describes this feature as “a fully-featured mobile experience for getting work done with Codex.”
Setup and Connectivity
Getting started requires the latest version of Codex for Mac and the ChatGPT mobile app for iOS or Android. The setup process begins on the Mac: after opening Codex, the application displays a QR code on the screen. Users then open the ChatGPT mobile app and scan that QR code to establish a secure, encrypted link between the phone and the Mac.
Once connected, the app loads the live state from the remote environment. This means users can work fluidly across active threads, approvals, plugins, and project context. The connection is persistent and updates in real time, allowing for seamless interaction even when the user walks away from their desk. OpenAI notes that files, credentials, permissions, and local setup remain on the machine where Codex is operating, ensuring security and data privacy. Only updates – including screenshots, terminal output, diffs, test results, and approval requests – flow back to the phone.
Features Beyond Remote Control
OpenAI stresses that this integration is more than simple remote desktop control. From the ChatGPT mobile app, users can manage all their Codex threads, review outputs, approve or deny commands, switch between different AI models, or start entirely new tasks. The mobile interface is not a stripped-down version; it provides full visibility into the agent’s progress and allows users to interact with the same complexity they would on the desktop.
This capability is particularly valuable for developers who need to monitor long-running code refactoring, test suites, or deployment pipelines while on the go. Project managers can also benefit by overseeing automated workflows without needing to be at a laptop. The mobile app supports multiple concurrent threads, so users can switch between different projects or environments easily.
Availability and Supported Platforms
The Codex remote access feature within ChatGPT is rolling out today for iOS and Android in all supported regions. Windows users will need to wait a bit longer – OpenAI has confirmed that support for remotely controlling Codex for Windows is coming soon. The company has not provided a specific timeline, but the announcement suggests it is a priority.
This release follows a period of rapid development for Codex. Last month, Codex on the Mac gained the ability to use apps on the computer without taking over the cursor, allowing users to run tasks simultaneously while retaining control of their machine. That update enhanced Codex’s utility as a collaborative agent rather than a fully autonomous system.
In addition to these enhancements, OpenAI recently introduced a subscription plan designed specifically for Codex users, along with the release of GPT-5.5, which upgrades the capabilities of both ChatGPT and Codex. The company also debuted Images 2, an improved image generation model integrated into its ecosystem.
Evolution of Codex
Codex originally debuted in February 2022 as a command-line interface tool, providing developers with a way to interact with OpenAI’s code-generation models directly from the terminal. The Mac graphical application arrived later in February 2026, offering a more intuitive interface for managing complex projects. The addition of mobile access marks a significant leap forward in making Codex a truly omnipresent assistant.
The evolution reflects a broader trend in the AI industry toward agentic systems that can operate autonomously over extended periods. By enabling mobile supervision, OpenAI acknowledges that users need to stay connected to their agents without being tethered to a desk. This aligns with the company’s vision of AI as a collaborative partner that works alongside humans across devices and locations.
Security and privacy remain central concerns. OpenAI has designed the mobile connection so that sensitive data – credentials, local files, permissions – never leaves the host machine. Only non-sensitive updates and interaction data are transmitted, and all communication is encrypted. This architecture alleviates common concerns about remote access tools exposing endpoints to potential attacks.
Impact on Developer Productivity
The mobile integration is likely to reshape how developers and teams incorporate Codex into their daily workflows. For example, a developer could ask Codex to refactor a large codebase while commuting, then approve or reject the changes from a phone. Or a team lead could review automated test results and adjust parameters without interrupting their current task.
OpenAI’s approach also lowers the barrier for non-developer stakeholders, such as product managers or QA engineers, who need visibility into the work Codex is performing. By embedding the remote interface in ChatGPT – which many already use for general AI assistance – the company reduces friction and encourages broader adoption.
The ability to work across multiple threads simultaneously further enhances productivity. Users can maintain separate contexts for different projects, each with its own set of plugins, models, and approval workflows. The mobile app displays the live state of each thread, providing up-to-date information on progress, pending approvals, and completed tasks.
As AI agents become more capable and autonomous, the need for human oversight remains essential. Mobile access ensures that oversight is not limited by physical location, enabling faster iteration and decision-making. This is particularly important for time-sensitive tasks such as deploying patches, reviewing security vulnerabilities, or optimizing performance bottlenecks.
The integration also hints at future possibilities. With Windows support on the horizon, Codex will soon be accessible from virtually any device, creating a truly cross-platform assistant ecosystem. Combined with ongoing improvements in model capabilities and subscription offerings, OpenAI is positioning Codex as an indispensable tool for modern software development and beyond.
