Agentic Browser
also: AI browser · agent browser
A browser driven by an AI agent that navigates and acts on web pages on the user’s behalf.
An agentic browser hands control of a real browser to an AI agent: it reads the page, clicks, types and navigates to accomplish a goal — researching, booking, purchasing. It unlocks broad reach over existing web UIs, but widens the attack surface, since a hostile page can try to hijack the agent through prompt injection.
Worked example: a browser driven by an AI agent that can read pages, click, fill forms, and navigate to complete a task (‘book this flight’, ‘extract these prices’) rather than just displaying pages for a human. Gotcha: the web is a hostile environment for autonomous agents — a page can carry prompt-injection that hijacks the agent, and an agent with your logged-in session can take real, irreversible actions (purchases, sends), so untrusted-content isolation and human confirmation on consequential steps are not optional; capability without those guardrails is a liability.
