What is AI Browser?
TL;DR
Next-generation web browser with AI agents deeply integrated into the browsing experience. Atlas and Comet led the wave in 2025–2026.
AI Browser: Definition & Explanation
An AI Browser is a next-generation web browser that integrates AI agents directly into the browsing experience. The address bar doubles as a prompt, pages get auto-summarized, you analyze multiple tabs at once, forms autofill, shopping and reservations happen on your behalf, and bookmarks become natural-language searchable. October 2025 saw OpenAI launch ChatGPT Atlas (Mac first) and Perplexity launch Comet (bundled with Max Pro at $200/month), kicking off the AI Browser category. Microsoft Edge has doubled down on Copilot integration, and The Browser Company released Dia as a successor to Arc. The thesis behind AI browsers is simple: the browser is the AI agent's working environment, and the AI continuously sees what you see and proposes the next action. The downside is privacy — browsing history and login state may flow to the AI provider — making enterprise governance the central challenge.
