Lesson preview

AI is moving from a tab you visit into the browser itself — AI-native browsers, extensions, and assistant-driven browsing let a model read, compare, and act on the pages you already have open. That power comes with a new safety surface: web pages are untrusted input, and credentials and purchases must stay firmly in human hands. For most of the browser's history, it has been a passive window: you look at pages, you click, you type. That's changing fast. AI-native browsers in the Dia/Arc lineage and Comet-style products build an assistant directly into the chrome of the browser, aware of every tab you have open. Alongside them, extensions add an AI layer to your existing browser, and assistant-driven browsing — like Claude given a browser tool — lets a general-purpose assistant reach out and act on the web on your behalf. These are three different shapes of the same idea: intelligence that sits at the browser level rather than in a single chat window, with access to whatever you're currently looking at. The simplest and most reliable use is page-level: summarize the article you're reading, extract the pricing table from the page in front of you, or pull every date mentioned into a list. Because the agent can see the actual rendered page — not just a static copy you pasted — it can work with dynamic content, expand FAQs, and follow visible structure. This alone eliminates a huge amount of copy-paste. Instead of selecting text, switching to a chat window, and pasting, you ask the question directly on the page you're already reading.

Browser agent
A browser agent is an AI agent that uses a web browser on your behalf: it reads pages, clicks, fills in forms and moves between tabs to complete a task. It can take over web chores you would otherwise click through by hand.
