Perplexity Comet Browser Review 2026: AI Browser Worth Switching?
Perplexity Comet is a Chromium-based AI browser that embeds an agentic assistant directly into your browsing session — reading your open tabs, filling forms, and executing multi-step tasks without you switching to a separate chat window.
