An AI browser puts an assistant inside the browser itself, so you can ask about the page in front of you without copying text into another app. The common jobs are the same across the field: summarize a long page, answer a question about it, compare two products, draft a reply in a text box, or tidy a pile of open tabs.
Most of the browsers here are built on Chromium, the open-source project behind Google Chrome. In practice that means Chrome extensions usually install and work, bookmarks import cleanly, and websites behave the same way. Firefox is the main exception, with its own engine and its own extension store, though popular extensions are often available for both.
The differences that matter are about data and control. When you ask about a page, the browser sends some or all of that page to an AI model, often in the cloud. Check whether that happens only when you ask or in the background, whether you can turn page context off for certain sites, and how long chat history is kept. If you are signed in with a work account, your organization's settings may limit what the assistant can see or switch features off entirely.
Think about logged-in sessions too. A browser assistant that reads the page can read a page from your bank, your email or your company's internal tools, because to the browser it is just another page. That is useful, and it is also a reason to keep the assistant off when you are working with private data you have no right to share.

Newer browsers are adding agent features that click and type for you. We list those in the browsing agents category once they are generally available, and we mark tools that are still in limited testing as unconfirmed until we can check them.
Switching costs are lower than they look. Every browser on this list can import bookmarks, saved passwords and history from the others, and the Chromium-based ones carry most extensions across too. A sensible way to try one is to install it alongside your current browser, import your data, and use it for one kind of work for a week, such as research or shopping, before you decide whether it earns a permanent place.
Keep an eye on account requirements as well. Some assistants work without signing in, while others need an account with the browser maker, and a few reserve the newer models or higher limits for a paid tier. If you share a computer, use separate browser profiles so one person's assistant history stays apart from another's.
No. Extensions such as Monica, Merlin or Grammarly add AI help to the browser you already use. A browser with an assistant built in mainly saves you an install and keeps the feature under one set of settings.
Usually only when you ask the assistant about a page, though settings vary. Look for a page context or similar setting, check whether it can be turned off per site, and read how chat history is stored for your account type.
