A common assumption about AI browsers is that they’re just a regular browser with a chatbot pinned to the side, a slightly fancier version of opening ChatGPT in a second tab. That’s not really what’s happening. The current wave of AI browsers, OpenAI’s ChatGPT Atlas, Perplexity’s Comet, and Anthropic’s Claude in Chrome, are built to act inside the page itself: reading what’s on screen, clicking buttons, filling in forms, and carrying out multi-step tasks without you doing the clicking. That’s a meaningfully different product than a chatbot that happens to live in your browser.
What Makes a Browser “Agentic”
The term getting used for this category is agentic browsing, and the distinction is about who does the work. A normal browser shows you a page and waits for you to act on it. An agentic browser can be told a goal, “compare flight prices across these three sites” or “fill out this form using the details from my last email”, and then actually perform the clicks, typing, and navigation needed to get there, checking in with you at points that matter rather than requiring you to supervise every step.
This only became practical recently because the underlying AI models got reliable enough at multi-step reasoning to plan a sequence of actions and adjust when something on a page doesn’t match expectations, rather than breaking after the first unexpected pop-up or layout change.
The Major Players Right Now
OpenAI’s ChatGPT Atlas launched in October 2025 as a full browser built with ChatGPT at its core, currently available on macOS with Windows, iOS, and Android support still rolling out. Its agent mode, which OpenAI describes as being able to research, book appointments, and complete purchases on a user’s behalf, is available in preview to paid subscribers, and the browser keeps a memory of pages you’ve visited to inform later chat responses, which users can review or turn off.
Anthropic’s Claude in Chrome takes a different shape: rather than a standalone browser, it’s an extension for Chrome that Anthropic says “reads the page you’re already signed in to, then clicks, types, and fills forms while you decide what happens next.” It’s now generally available on all paid Claude plans, and Anthropic has built in a separate safety check that reviews planned actions before they run, plus a requirement that sensitive actions like financial transactions pause for explicit approval.
Perplexity’s Comet was the earliest of the three to ship, launching in mid-2025 and rolling out free to everyone worldwide that October. Perplexity frames it around an “assistant” that carries out browsing sessions on your behalf, from cross-referencing multiple open tabs to booking a meeting, while leaning on Perplexity’s own search and answer engine underneath.
What They’re Actually Good At Today
Where these tools consistently deliver value right now is on well-defined, repetitive browser tasks: pulling the same piece of information from several sites and comparing it, filling out a form using details you’ve already provided elsewhere, or summarizing a long page without you having to scroll through it yourself. That overlaps a lot with how people already lean on ChatGPT for work tasks, just moved a layer deeper into the browser instead of a separate chat window. Fully autonomous, “book my entire vacation” style tasks are demoed regularly but still tend to need a human check-in partway through, since travel and purchase sites change their layouts often enough to trip up an agent that isn’t watching closely.
The Real Risk: Prompt Injection
The most serious concern with agentic browsers isn’t that they’ll misclick occasionally, it’s prompt injection: hidden text on a webpage, invisible to a human but readable by the AI, that tries to redirect the agent into doing something the user never asked for, like submitting a form to a different address or approving a purchase. OpenAI’s own documentation for Atlas acknowledges that agents “carry risk” including “susceptibility to hidden malicious instructions,” and Anthropic’s Claude in Chrome page describes a dedicated safety layer built specifically to catch “instructions hidden by the site” before an action executes. Both companies treat this as an active, ongoing problem rather than one that’s fully solved, which is worth knowing before handing an agent your logged-in accounts.
Should You Switch Your Everyday Browser?
For most people, not yet, at least not as a full replacement for Chrome, Safari, or Edge. These tools are genuinely useful as an occasional assistant for specific repetitive tasks, but the practical value today comes from picking one, giving it low-stakes tasks first, and building a sense of where it saves real time versus where it’s faster to just do the click yourself. That’s the same “start small” approach that pays off with AI agents more broadly and with any of the major AI chatbots people already use daily. Given how quickly all three companies are shipping updates, the safest habit is checking each product’s own release notes before granting it broad access to accounts that matter, rather than assuming today’s safety features are the final word.
The Bottom Line
AI browsers are a real category, not a rebrand of the chatbot sidebar, because they act inside pages instead of just answering questions about them. The technology is early enough that hidden-instruction attacks remain an open problem across every major entrant, so the sensible approach is treating agent mode as a capable assistant to supervise, not a set-it-and-forget-it feature to hand your accounts to.
FAQs
What’s the difference between an AI browser and just using a chatbot?
A chatbot answers questions and can draft text, but it doesn’t act inside a webpage on its own. An AI browser can click buttons, fill in forms, and navigate between pages to actually complete a task, with the chatbot’s reasoning driving those actions rather than just producing a written response.
Are AI browsers safe to use with logged-in accounts like email or banking?
All three major AI browsers include some form of approval step for sensitive actions, and none of the makers claim the underlying prompt-injection risk is fully solved. It’s reasonable to use them for lower-stakes browsing and researched tasks while being more cautious about granting full access to financial or highly sensitive accounts.
Do I need to pay for an AI browser to use its agent features?
It varies by product. Comet is free to use worldwide, while ChatGPT Atlas’s agent mode is currently limited to paid ChatGPT subscribers, and Claude in Chrome is available on Claude’s paid plans rather than the free tier.
Can an AI browser replace my regular browser entirely?
Not yet for most people. They’re best used alongside a regular browser for specific tasks right now, since full autonomous browsing still occasionally needs a human check-in when a website’s layout or flow doesn’t match what the agent expected.
Is Google building its own AI browser too?
Google has been adding AI features directly into Chrome rather than shipping a separate agentic browser the way OpenAI, Anthropic, and Perplexity have, which is part of why this category is often described as a competitive response aimed at Chrome’s dominance rather than a shift Google itself started.
