OpenAI Unveils Codex “Superapp” Update with Computer Use, Automations, Built-In Browser, and More

Today, OpenAI introduced a long list of productivity and coding updates to Codex. I haven’t had a chance to try the new features myself yet, but the demo OpenAI gave me was as impressive as the company’s message was clear: Codex isn’t just for coders anymore.

It was just over a week ago that OpenAI raised $122 billion in financing and announced it was shifting its focus to building a superapp that brings the capabilities of its models into a unified experience. It turns out that app is Codex, OpenAI’s app that, until today, was focused primarily on developing software.

However, according to OpenAI, 50% of Codex’s users were already giving it non-coding tasks to complete. Combined with the OS flexibility of a desktop environment, that made Codex the natural place to bring together a wide range of new productivity and coding features.

On the productivity side of things, the update allows Codex to operate your desktop apps, interacting with interface elements and inputting text, for example. We’ve seen computer use from other AI companies before, but one thing that sets Codex apart is its ability to work in your apps in the background so they don’t steal the focus from whatever app you’re already using.

OpenAI has drawn aspects of its Atlas browser into Codex, too. This allows Codex to prototype websites and apps that users can comment on in-line, creating a tight feedback loop for refining designs. Currently, this feature is limited to running sites and apps via a local server setup, but OpenAI says it will be extended to incorporate actions like interacting with the greater Internet, taking screenshots, and stepping through user flows in the future.

Plugins are taking a big leap forward as well, with over 100 being added to the mix. Like the Claude plugins that Anthropic offers, Codex plugins are composed of a bundle of skills, app integrations, and MCP servers. According to OpenAI, the list includes many popular third-party tools and services like the Microsoft suite, Atlassian Rovo, CodeRabbit, Render, and Superpowers. One of my favorite moments in the Codex demo I saw was a prompt that simply asked, “Can you check Slack, Gmail, Google Calendar, and Notion and tell me what needs my attention?” It’s the sort of query that I think a lot of people can relate to as they start a busy day, and it’s all driven by stacking multiple plugins.

OpenAI is also testing an enhancement of Codex’s memory feature as a preview that learns from you as you work. Codex will pick up on your preferences, corrections you make, and context from the tasks you give it. This is the sort of feature that is hard to demo, so I don’t have a good sense for it yet, but I expect that over time, its practical utility will become more clear.

One place OpenAI says Codex’s enhanced memory system will help is with new proactive suggestions. As the app learns your preferences and work patterns, it will offer suggestions on what to do next or where to pick up where you left off. Again, how well this will work in practice remains to be seen, but this is exactly the sort of thing that has made OpenClaw so popular. Having an agent that understands your preferences and accesses your messages, files, and other data in a proactive way can be incredibly useful if done well.

Automations have been expanded, too, allowing Codex to use past threads and schedule tasks over days or weeks. These heartbeat automations stay in the same Codex thread and can be modified by the model itself, allowing it to schedule its own follow-ups – again, very much like OpenClaw.

Also new to Codex is support for gpt-image-1.5 for creating image assets as part of workflows like creating presentations, website mockups, and product concepts.

Although the focus of today’s update is on productivity, developers haven’t been forgotten. New development features include:

Fast frontend iteration using a combination of the in-app browser, computer use, and image generation tools;

Multiple terminal tabs;

A file sidebar for previewing PDFs, spreadsheets, slides, and other formats;

GitHub PR review support, allowing for review of comments inside Codex;

A summary pane that tracks plans, sources, and artifacts in a single view; and

Remote devbox SSH, an alpha feature for connecting to remote development environments.

That’s a lot, but with more than three million users per week, Codex has proven its popularity well beyond its core coding audience. I’m still skeptical about how much functionality a single app can support, especially when OpenAI addresses the mobile market. I also wonder whether Codex’s productivity and developer tools can coexist without alienating some segment of the app’s users. However, proactive automation of busy work and sifting through mountains of messages and other data is precisely what I’ve wanted from Codex from the start. I’ve seen what it can do when I’m working on a script or app and can’t wait to apply that to my everyday work, too.

Today’s Codex update is available in the desktop app to users with a signed-in ChatGPT account. Computer use is a Mac-only feature at launch (undoubtedly thanks to macOS’s deep accessibility support that was the basis of the same sort of computer use magic we saw in Sky, which was acquired by OpenAI last year), and a rollout of the new features will happen in the EU later. Personalization features like proactive suggestions and the memory enhancements will be coming to Enterprise, Edu, and EU users soon, too.
