AI-powered browsers give you much more than a window to the web. They represent an entirely new way to experience the internet, with an AI “agent” working by your side.

We’re entering an age where you can delegate all kinds of tasks to a browser, and with that comes a few things you’ll want to keep in mind when using AI browsers like ChatGPT’s Atlas, Perplexity’s Comet, and others.

What are agentic AI browsers?

So, what’s the allure of this new breed of browser? The answer is that it’s highly helpful, and plenty more.

By design, these “agentic” AI browsers actively assist you with the things you do online. They can automate tasks and interpret your intentions when you make a request. Further, they can work proactively by anticipating things you might need or by offering suggestions.

In a way, an AI browser works like a personal assistant. It can summarize the pages in several open tabs, conduct research on just about any topic you ask it to, or even track down the lowest airfare to Paris in the month of May. Want it to order ink for your printer and some batteries for your remote? It can do that too. And that’s just to name a few possibilities.

As you can see, referring to the AI in these browsers as “agentic” fits. It truly works like an agent on your behalf, a capability that promises to get more powerful over time.

Is it safe to use an AI browser?

But as with any new technology, early adopters should balance excitement with awareness, especially when it comes to privacy and security. You might have seen some recent headlines that shared word of security concerns with these browsers.

The reported exploits vary, as does the harm they can potentially inflict. That ranges from stealing personal info, gaining access to Gmail and Google Drive files, installing malware, and injecting the AI’s “memory” with malicious instructions, which can follow from session to session and device to device, wherever a user logs in.

Our own research has shown that some of these attacks are now tougher to pull off than they were initially, particularly as the AI browser companies continue to put guardrails in place. If anything, this reinforces a long-standing truth about online security, it’s a cat-and-mouse game. Tech companies put protections in place, bad actors discover an exploit, companies put further protections in place, new exploits crop up, and so on. It’s much the same in the rapidly evolving space of AI browsers. The technology might be new, but the game certainly isn’t.

While these reports don’t mean AI browsers are necessarily unsafe to use, they do underscore how fast this space is evolving…and why caution is smart as the tech matures.

How To Use an AI Browser Safely

It’s still early days for AI-powered browsers and understanding the security and privacy implications of their use. With that, we strongly recommend the following to help reduce your risk:

Don’t let an AI browser do what you wouldn’t let a stranger do. Handle things like your banking, finances, and health on your own. And the same certainly goes for all the info tied to those aspects of your life.

Pay attention to confirmations. As of today, agentic browsers still require some level of confirmation from the user to perform key actions (like processing a payment, sending an email, or updating a calendar entry). Pay close attention to them, so you can prevent your browser from doing something you don’t want it to do.

Use the “logged out” mode, if possible. As of this writing, at least one AI browser, Atlas, gives you the option to use the agent in the logged-out mode.ⁱ This limits its access to sensitive data and the risk of it taking actions on your behalf with your credentials.

If possible, disable “model learning.” By turning it off, you reduce the amount of personal info stored and processed by the AI provider for AI training purposes, which can minimize security and privacy risks.

Set privacy controls to the strictest options available. Further, understand what privacy policies the AI developer has in place. For example, some AI providers have policies that allow people to review your interactions with the AI as part of its training. These policies vary from company to company, and they tend to undergo changes. Keeping regular tabs on the privacy policy of the AI browser you use makes for a privacy-smart move.

Keep yourself informed. The capabilities, features, and privacy policies of AI-powered browsers continue to evolve rapidly. Set up news alerts about the AI browser you use and see if any issues get reported and, if so, how the AI developer has responded. Do routine searches pairing the name of the AI browser with “privacy.”
