Perplexity Comet Review 2026: Pricing, Features, Pros & Cons
Comet is Perplexity's Chromium-based AI browser that searches, summarizes, and acts on web pages for you — and as of March 2026, it's free. Here's an honest look at what it does well, where the agentic browsing model still trips up, and whether it's worth replacing Chrome.
Quick Verdict
Best for: Researchers, shoppers, and power users who want an AI assistant that can act inside the browser — not just chat about what's on screen. Since Comet is now free and built on familiar Chromium foundations, it's a low-risk browser to try even if you keep Chrome as a backup.
What Is Perplexity Comet?
Comet is a full web browser built by Perplexity on top of Chromium, with an AI agent embedded at the browser level rather than bolted on as an extension. Instead of copying text into a chat window, you ask Comet questions about whatever page — or set of tabs — you have open, and it can act directly: filling out forms, comparing prices across sites, summarizing long articles, or completing a multi-step booking flow.
The defining shift for 2026 is pricing. Comet launched as a Perplexity Pro perk, but on March 18, 2026 Perplexity dropped that requirement and made the core browser free on Mac, Windows, iOS, and Android. Paid tiers now layer on top: Comet Plus ($5/mo) unlocks premium publisher content from launch partners like Conde Nast, CNN, Fortune, and The Washington Post, while Max ($200/mo) adds autonomous Background Assistants that run tasks without you watching.
Because it's Chromium-based, switching from Chrome or Edge is low-friction — extensions, bookmarks, and saved logins largely carry over, so you're not giving up your existing setup to try the agentic features.
Comet Pros & Cons
✓ Pros
- •Now completely free: Comet dropped its Pro-only paywall on March 18, 2026 and is available free on Mac, Windows, iOS, and Android — removing the biggest adoption barrier it had at launch
- •Agentic browsing that actually acts: Comet doesn't just answer questions about a page — it fills out forms, adds items to a cart, books reservations, and completes multi-step tasks directly inside the browser tab, not in a separate chat window
- •Built on Chromium: Existing Chrome extensions, bookmarks, and saved passwords carry over, so switching doesn't mean giving up your browser setup
- •Deep Research without leaving the tab: You can trigger Perplexity's Deep Research mode on whatever page you're viewing and get a sourced, cited report without opening a new app
- •Tab-aware assistant: The sidebar assistant can summarize, compare, and answer questions using the content of your currently open tabs, which is genuinely useful for research-heavy browsing sessions
- •Voice mode for hands-free browsing: You can narrate a task — 'find me a flight to Austin next Friday under $300' — and Comet will search and act without typing
- •Premium publisher content via Comet Plus: Comet Plus (or free with Pro/Max) unlocks direct access to Conde Nast titles, CNN, Fortune, The Washington Post, and other launch partners inside search results, instead of hitting paywalls
✗ Cons
- •Best features still gated behind Pro/Max: The free tier covers agentic search, summarization, and voice mode, but Background Assistants — tasks that run autonomously without you watching — require the $200/mo Max plan
- •Agentic actions can misfire: Auto-filling forms or completing checkout flows is powerful but occasionally picks the wrong option or field, especially on sites with unusual layouts. Always double-check before confirming a purchase or booking
- •Privacy tradeoff is real: An AI browser that can read every open tab and act on your behalf needs broad permissions. Users handling sensitive data (banking, healthcare, legal work) should weigh this carefully before making Comet a daily driver
- •Extension compatibility isn't perfect: While built on Chromium, some heavier extensions (certain ad blockers, password managers with deep browser hooks) report occasional conflicts with Comet's assistant layer
- •Comet Plus content depth varies by publisher: Launch partners are strong, but coverage outside those specific outlets is no different from a normal paywalled search result
- •No desktop Linux build: Comet ships for Mac, Windows, iOS, and Android — Linux users are left out, which matters for a meaningful slice of the developer audience Perplexity otherwise targets
- •New browsing paradigm has a learning curve: Long-time Chrome or Safari users need to relearn muscle memory around the AI-first address bar and sidebar-driven workflows before Comet feels faster than a traditional browser

Who Should Use Comet?
Researchers & Students
Deep Research triggered directly from a tab, plus tab-aware summarization, makes literature review and comparison shopping for sources noticeably faster than switching between a browser and a separate chat app.
Online Shoppers
Comet's shopping assistant can compare prices across tabs and complete checkout flows, which is a real time-saver for anyone who regularly comparison-shops before buying.
News Readers
Comet Plus subscribers (or Pro/Max users) get direct access to major outlets like the Washington Post and CNN inside search, avoiding individual paywalls for casual readers.
Chrome Users Willing to Experiment
Because Comet is Chromium-based and now free, it's a low-risk way to test agentic browsing without abandoning your extensions or bookmarks — you can always switch back.
Frequently Asked Questions
Is Perplexity Comet actually free now?
Yes. Comet dropped its Pro-subscriber-only requirement on March 18, 2026 and is now free to download and use on Mac, Windows, iOS, and Android. The core agentic search, summarization, voice mode, and shopping assistant features are all included at no cost. Comet Plus ($5/mo) and Max ($200/mo) add publisher content and autonomous background tasks respectively, but neither is required to use the browser.
Is Comet safe to let it fill out forms and make purchases?
Comet can act directly on pages — adding items to carts, filling forms, completing bookings — which is convenient but means it needs broad page access. It generally shows you what it's about to do before finalizing purchases, but review any auto-filled information before confirming, especially payment and shipping details. For sensitive accounts (banking, healthcare), consider using a traditional browser instead.
How is Comet different from just using Perplexity's website or app?
The Perplexity website and app are a search/chat interface you visit. Comet is a full Chromium-based web browser that replaces Chrome or Safari as your daily driver, with the AI assistant embedded at the browser level — meaning it can read and act on any tab you have open, not just answer isolated questions.
Does Comet work with my existing Chrome extensions?
Comet is built on Chromium, so most Chrome Web Store extensions install and run normally, including bookmarks and saved data import. A minority of extensions with deep browser-level hooks — some ad blockers and password managers — have reported occasional conflicts with Comet's assistant layer, so test your critical extensions after switching.
Comet vs Dia — which AI browser should I use?
Comet is free with broader platform support (Mac, Windows, iOS, Android) and includes Deep Research plus a publisher content bundle. Dia, from The Browser Company, is Mac-only (Apple Silicon required) and leans more on cross-tab memory and meeting-aware tab grouping, with its deeper features locked behind a $20/mo Pro plan. If you're not on a Mac, or want free agentic browsing, Comet is the easier default. If you live in Mac-native workflows and want a more personal, memory-driven assistant, Dia is worth trying during its free tier before deciding on Pro.
