An AI browser is a web browser with a built-in AI assistant that summarises pages and can carry out tasks on the web for you.
Example
You ask the browser to compare three product pages, and it builds you a table.
For pros
Because the assistant reads web content and acts on your behalf, hidden instructions on web pages (prompt injection) are a known risk. Security researchers publicly demonstrated such attacks in 2025. Don't stay logged in to banking or email accounts for agent tasks, and check every step.
