The best AI browser tools in 2026 bring AI to the pages you are already on. Gemini is built into Chrome for summarizing and asking about pages, Claude offers a Chrome extension on paid plans, Grammarly checks your writing in any text box, and Brisk helps teachers inside Google Docs and Classroom. AI browsers such as Perplexity’s Comet go further by building AI into the whole browser. Because extensions can read what you browse, install only what you trust.
