Comet is a Chromium-based browser from Perplexity AI that replaces traditional search with an always-available AI assistant aware of your current browsing context. Instead of typing a query and scanning results, you ask questions in natural language and get synthesized, citation-backed answers drawn from your current tab, all open tabs, or the broader web. The assistant can also fill out forms, help you shop, summarize content from multiple pages simultaneously, and complete multi-step browsing tasks. Comet launched for Windows and macOS in July 2025, arrived on Android in November 2025, and reached iOS in March 2026. It is free for all Perplexity account holders, with an optional Comet Plus tier at $5/month for access to premium publisher content. The browser includes a built-in ad blocker with whitelist controls. Comet's strength is research: it maintains context across tabs and synthesizes information automatically rather than requiring you to hold everything in your head. It sits alongside Dia (from The Browser Company) and ChatGPT Atlas as part of a new wave of AI-first browsers competing to replace the standard Chrome workflow for knowledge workers.

What the community says

Comet gets positive reception from knowledge workers who spend hours researching and switching between browser tabs. Reviewers on cybernews and tech forums highlight the tab synthesis capability as genuinely time-saving for research-heavy work, with users comparing it favorably to paying for separate summarization tools. The free pricing removes the risk barrier to trying it. Common criticisms include concern about browsing data being processed by Perplexity servers, the browser feeling less stable than Chrome or Firefox for general daily use, and early adopters finding it slower to load than expected. Users who want pure research capability rate it highly, while general browsing users find the AI features intrusive more than helpful.
