Forget tabs. Agentic Browsing allows the browser to do the work for you.

Tools: ChatGPT Atlas (Agent Mode) or Perplexity Comet (Comet Assistant).

Time required: 20 minutes for a test drive

What changed in 2025?

Traditional browsers just display pages. AI browsers (Agentic Browsers) can act:

  • Agent Mode (Atlas): You say "Plan a trip to Paris", and the browser opens Booking, Airbnb, searches for tickets, and compiles a table of options itself.

  • Browser Memories: Atlas remembers you were looking for a gift for mom a week ago and suggests relevant ideas.

  • Comet Assistant: Perplexity Comet integrates search deep into surfing, allowing you to compare products from different stores in one sidebar.
