About Perplexity Comet

Perplexity Comet is Perplexity's Chromium-based AI browser, built around agentic browsing — an assistant that doesn't just answer questions about a page but fills out forms, adds items to a cart, books reservations, and completes multi-step tasks directly inside the tab. Comet dropped its Pro-subscriber-only paywall on March 18, 2026 and is now free on Mac, Windows, iOS, and Android. Beyond agentic actions, Comet brings Perplexity's Deep Research mode into the browser itself — triggerable on whatever page you're viewing for a sourced, cited report without opening a separate app — along with a tab-aware sidebar assistant and voice mode for hands-free browsing. Comet Plus ($5/mo, included free with Pro/Max) unlocks premium publisher content from launch partners like Conde Nast, CNN, Fortune, and The Washington Post inside search results instead of hitting paywalls. Built on Chromium, it carries over existing Chrome extensions, bookmarks, and saved passwords.

Perplexity Comet Pros & Cons

✅ Pros

+Completely free since dropping its Pro-only paywall on March 18, 2026
+Agentic browsing acts directly in the tab instead of routing through a separate chat window
+Deep Research is available in-browser with sourced, cited reports
+Tab-aware assistant is genuinely useful for research-heavy browsing sessions
+Comet Plus gives access to major publisher content without individual subscriptions

⚠️ Cons

−Background Assistants — tasks that run autonomously unattended — require the $200/mo Max plan
−Agentic actions can occasionally misfire on unusual page layouts, so purchases and bookings need double-checking
−Broad page-read and action permissions are a real privacy tradeoff for sensitive browsing (banking, healthcare, legal)
−No desktop Linux build, unlike some competing AI browsers
−AI-first address bar and sidebar workflow has a learning curve for longtime Chrome/Safari users
