Codex is now integrated into the ChatGPT mobile app, so you can keep tabs on progress while letting Codex keep working on your laptop, development machine, or remote environment while you’re on the go.
As agents take on longer-running tasks, a new rhythm of collaboration is emerging. To keep work moving, you need a way to answer questions, review what Codex found, adjust direction, approve the next step, or bring in a new idea without breaking momentum.
Today, more than 4 million people use Codex each week, and the importance of these small moments is becoming increasingly clear. A quick check-in can keep work flowing, prevent unnecessary rework, and help Codex move forward with the right context. Soon, you’ll be able to handle these interactions directly from your phone. Get started here.
Stay connected to active work from anywhere
Codex in the ChatGPT mobile app is a full-featured mobile experience designed to keep your Codex work moving smoothly. When you connect to any machine where Codex is running — whether that’s your laptop, a dedicated Mac mini, or a hosted remote environment — the app loads the live state of that environment. That means you can move seamlessly between active threads, approvals, plugins, and project context.
This isn’t just about remotely controlling a single task or handing work off to your own computer. It’s about being able to work across all your threads on your phone, review outputs, approve commands, switch models, or start new tasks. Files, credentials, permissions, and local configuration stay on the machine where Codex is running, while updates like screenshots, terminal output, diffs, test results, and approvals are reflected on your phone in real time.
Under the hood, Codex uses a secure relay layer that keeps trusted machines reachable across devices without exposing them directly to the public internet. The relay layer also syncs the state and context of active sessions from wherever you’re signed into ChatGPT.
Step in when it matters
As Codex takes on longer cycles of work, timely guidance becomes even more important and is essential to preserving the value of that work. You can start work from your phone at any time, unblock decisions when they arise, and keep following along as results gradually take shape.
With Codex in your pocket, you can now:
- Start debugging a bug while waiting for coffee. Because Codex runs in your development environment, it can inspect the relevant files, reproduce the issue in a browser, run tests, and begin the fix. If Codex needs clarification or approval to continue, you can respond or approve it directly from your phone. You can check screenshots, terminal output, and test results as they come in, and review the generated diff before you’re back at your desk.
- Move decisions forward during your commute. Before heading to work, you handed Codex a time-consuming refactor and planned to review the results once you arrived. Partway through the commute, Codex found two viable approaches and needed guidance to proceed. You review the trade-offs on your phone, choose a path, and by the time you arrive, the work is already continuing in the direction you want.
- Prepare more thoroughly before a fast-moving customer call. After a string of meetings, you notice that support issues have been progressing across Slack, email, documents, and browser-based tools, and your next customer call is about to begin. From your phone, you can ask Codex to organize the latest updates, identify the key open questions, and draft a concise briefing for the conversation. If new information comes in, you can have it refresh the summary before you join the meeting.
- Capture ideas while they’re fresh. During lunch, on a walk, or the moment something you see or hear sparks an idea, you can send a new thought to Codex from your phone. You can start a new thread or add to one already in progress. By the time you’re back at your desk, the task may already have momentum, and the idea hasn’t slipped away.
Run Codex in enterprise environments
Many teams already develop in hosted remote environments with approved dependencies, credentials, security policies, and compute resources.
With Remote SSH now generally available, Codex can connect directly to these environments. The desktop app automatically detects hosts in your SSH configuration and lets you create projects and run threads on remote machines with the same feel as working locally.
Once connected, these environments remain reachable across authorized ChatGPT devices through the same secure relay infrastructure. That means you can start work on desktop, direct execution from your phone, and keep long-running tasks moving without being tied to a single machine.
We’ve also added a few updates to broaden how teams can automate, customize, and govern Codex in larger environments:
- Programmatic access tokens provide scoped credentials and can be issued directly from your ChatGPT workspace settings. They can be used for CI pipelines, release workflows, and internal automation.
- Hooks are now generally available and can be used to scan prompts for secrets, run validation tools, log conversations, create memories, or customize Codex’s behavior for specific repositories or directories.
- HIPAA-eligible use of Codex in local environments (CLI, IDE, App) is now available for ChatGPT Enterprise workspaces, helping healthcare organizations support patient care and operational workflows with greater speed and confidence.

Codex in the ChatGPT mobile app is rolling out in preview on iOS and Android across supported regions for all plans, including Free and Go.
