Agentic Browser in plain English.

An agentic browser is a web browser with AI built in deeply enough to complete multi-step tasks on your behalf, not just summarize or chat about the page you're looking at. Ask it to book a restaurant reservation, fill out and submit a multi-page form, or compile research by reading across a dozen open tabs, and it drives the browser itself — clicking, typing, navigating — the way a person would, rather than handing you an answer to copy and paste yourself. That's a step beyond earlier "AI browser" features like page summarization or a sidebar chat assistant, which only read a page rather than acting inside it. Products like Perplexity's Comet, The Browser Company's Dia, and OpenAI's ChatGPT Atlas all compete in this category, each betting that the browser itself — not a separate app — is where everyday agentic AI work should happen in 2026. Reliability on genuinely open-ended, multi-step tasks remains the category's main limitation.
