AI browsers: agents that browse for you

What you'll see in this lesson

1. Agentic browsers: from reading to acting

   An AI browser doesn't just summarize pages: it clicks, types and fills in forms for you with your open sessions.

2. Comet: Perplexity's browser

   Comet has been free for everyone since October 2025 and brings Perplexity's assistant to every tab.

3. Gemini in Chrome and its auto browse

   Gemini lives in Chrome's side panel and its auto browse completes tasks for you, but it hasn't reached Spain yet.

4. Claude in Chrome: an extension that takes action

   Since August 2026, Claude in Chrome has been generally available on all paid Claude plans.

5. What happened to ChatGPT Atlas

   OpenAI launched Atlas in October 2025, for Mac only, and shut it down on August 9, 2026.

6. Which tasks to delegate and which not to

   Delegate what's repetitive and easy to check; keep for yourself anything involving money, personal data or your reputation.

7. The big risk: prompt injection

   A website, an email or a PDF can hide commands for the agent, and it may obey them as if they came from you.

8. Rules before letting an agent browse

   Treat the agent like an intern with your keys: little access, well-defined tasks and you checking what matters.

9. Summary: agentic browsers

   Web agents save time on repetitive tasks, but they act with your sessions: give them little access and keep watch.
