ChatGPT Agents: Browser, Computer Use and Sites Explained
Short Answer: ChatGPT is no longer confined to the chat window. As a ChatGPT agent, it can now work inside a browser and on your computer - clicking, navigating, filling in forms and completing tasks on your screen while you watch and approve each step. It can also build simple interactive websites through a feature called Sites, with no code required. You stay in charge: it acts, you approve.
If you've ever watched someone share their screen and thought "I wish I could just hand this over" - this post is for you.
Because that's essentially what's now possible. ChatGPT has stepped outside the chat window. It can open a browser, click buttons, navigate pages and complete tasks on a screen, with you watching it happen. And with a feature called Sites, it can build you a simple website or tool without you writing a single line of code.
If that sounds slightly unbelievable, or slightly nerve-wracking, or both - you're in good company. Most people we teach feel exactly that mix. So in this post, part three of our August series on the new ChatGPT, we'll walk through what these features actually do, what they're genuinely useful for at the beginning, and how to try them safely without putting your business or your data at risk.
No jargon. No pressure. Just a clear picture of what's now possible.
What is a ChatGPT agent, in plain English?
An AI agent is AI that takes actions, not just AI that gives answers.
Ordinary ChatGPT tells you how to do something: "here are the steps to update your details on that website." A ChatGPT agent does the something: it opens the website, finds the right page, fills in the form and stops to ask before submitting.
Think of the difference between a recipe and a cook. Both involve the same knowledge. Only one of them gets dinner made.
Until recently, this kind of capability lived mostly in specialist tools. Now it's built into ChatGPT itself, in two main forms: working in a browser, and working on your computer through the desktop app. Last week we looked at ChatGPT Work, where you delegate whole documents and reports. This week's features take the same idea one step further - out of the document and onto the screen.
ChatGPT in your browser
Inside the ChatGPT desktop app there's now a built-in browser that ChatGPT can use alongside you. Ask it to research something, and instead of describing what it might find, it actually visits the pages, reads them, compares what's there and brings back what it found - sources included.
Where this starts to feel genuinely new is with tasks, not just research:
Comparing prices or options across several websites and summarising the differences.
Finding and filling in a form - a supplier enquiry, a directory listing, an event registration - and pausing for you to check before it submits.
Navigating a website you find fiddly and doing the clicking for you.
You can watch it work in real time, step in whenever you like, and nothing important happens without your say-so. It's less like handing over your keys and more like having someone drive while you sit beside them with your hand near the brake.
ChatGPT on your computer
Computer use goes one step further again. Through the desktop app, ChatGPT can interact with what's on your screen - moving between windows, working with your files and applications, and carrying out multi-step tasks that span more than one program.
A realistic early example: "take the details from this PDF and enter them into this spreadsheet." A task that's not hard, just tedious - which is exactly the kind of task worth delegating first.
Now for the honest part, because we promised no hype. This capability is new, and new means imperfect. It will sometimes click the wrong thing, misread a screen, or take a slower path than you would. That's not a reason to avoid it - it's a reason to start small. Here's the safety checklist we teach:
Start with low-stakes tasks. Nothing involving payments, passwords, client data or anything you couldn't easily undo.
Watch the first few runs. You'll quickly learn what it handles well and where it stumbles.
Keep approval steps on. Anything that submits, sends or deletes should wait for your confirmation.
Treat it like a new starter. Capable, fast, keen - and not yet ready to work unsupervised.
The pattern is the same one we've repeated all series: it acts, you approve. AI drafts, humans review, humans publish - and when the "draft" is an action on your screen, the review step matters even more.
Sites: build a simple website or tool without code
Now for the creative part - and honestly, the most fun.
Sites is a feature that turns your ideas, plans and data into simple interactive websites and web apps. You describe what you want, and ChatGPT builds it - a page you can use, share and update, without touching code.
What are people actually building? Things like:
A project tracker the whole team can see, that stays up to date as things change.
A simple dashboard showing the numbers that matter, drawn from a spreadsheet.
A launch calendar for a campaign, shared with a client.
A small calculator or quiz for your audience - "what's your event budget?", "which package suits you?"
A quick prototype of an idea, to see it working before investing anything more.
If this rings a bell, it's because it's part of a wider shift we explored in June: interactive content and vibe coding, where describing what you want has replaced knowing how to build it. Our guide to building interactive content with AI pairs perfectly with Sites - the thinking is the same, and now the tool is built right into ChatGPT.
The barrier that used to stand between "I have an idea for a little tool" and "the tool exists" was a developer. That barrier is mostly gone. What matters now is knowing which small tool would genuinely help your business or your audience - and that's a question about your customers, not about technology. Focus on the task, not the tool.
Your first safe experiment this week
You don't need to be technical, brave or ready. You just need twenty minutes and a low-stakes task. Pick one of these:
A browser task - ask ChatGPT to compare three options for something you genuinely need (a venue, a printer, an insurance quote) and bring back a summary with sources.
A screen task - hand over one tedious copy-this-into-that job, and watch it work.
A Sites task - describe one small tool you've always wished existed for your business, and see what it builds.
Whichever you choose, you'll learn the thing that no article can teach you: what it feels like to delegate to AI and stay in charge at the same time. That feeling - not any feature - is the real skill of 2026.
And if you'd rather not figure it out alone, you don't have to. That's rather the point of everything we do.
Our free webinar, Create an AI-Powered Business, walks you through building AI into your business step by step - in plain language, at a beginner-friendly pace, with a clear system to follow.
Frequently Asked Questions
Can ChatGPT really use my computer?
Yes - through the ChatGPT desktop app, it can interact with what's on your screen: navigating websites, working across windows and completing multi-step tasks. You watch it work, and actions that submit, send or change anything important wait for your approval.
Is it safe to let a ChatGPT agent click and navigate for me?
It's safe when you start sensibly. Begin with low-stakes tasks, watch the first few runs, keep approval steps switched on, and never hand over anything involving payments, passwords or sensitive client data until you've built real confidence.
What is ChatGPT Sites?
Sites is a feature that turns your ideas, plans and data into simple interactive websites and web apps - project trackers, dashboards, calculators, prototypes - with no coding required. You describe what you want, ChatGPT builds it, and you can share and update it as things change.
Do I need coding skills to build a website with AI?
No. For simple sites and tools, describing what you want clearly is the skill - who it's for, what it should do, and what information it needs to show. If you can brief a person, you can brief the AI.
What's the difference between ChatGPT Work and a ChatGPT agent?
They're parts of the same shift. ChatGPT Work produces finished deliverables like documents, spreadsheets and reports from a brief. Agent capabilities - the browser and computer use - take actions on a screen: clicking, navigating and completing tasks. Both follow the same rule: it acts, you approve.
