From Exclusive Launch to Free for All: The Comet Journey
Understanding how Comet evolved from an ultra-premium offering to a free browser for everyone helps contextualize this announcement's significance. Here's the complete timeline:
The Evolution Timeline
- July 2024: Perplexity launches Comet exclusively for Max subscribers at $200 per month—one of the most expensive browser offerings ever introduced.
- Summer 2024: Gradual invite-only access begins rolling out to users on the waitlist, creating significant buzz in the productivity community.
- August 2024: Access expands to select Perplexity Pro users in the United States, reducing the barrier from $200 to the Pro subscription price.
- September 2024: Broader international rollout reaches Pro users in India, Germany, and other regions as Perplexity tests market demand.
- October 2, 2025: Complete free access launches worldwide. CEO Aravind Srinivas announces this aligns with their mission to "build a better internet" that's "accessible to everybody."
What's included in the free version: Everything. The full Comet browser with AI assistant, Comet Plus subscription features (previously $5/month), premium publisher content from CNN, The Washington Post, Fortune, and more, plus built-in ad blocking and privacy controls. There are no tiers or limitations.
What Makes Comet Different: Beyond Traditional Browsing
Most browsers in 2025 have added AI features as plugins or sidebars. Comet takes a fundamentally different approach by building artificial intelligence into its core architecture from the ground up. This isn't Chrome with a chatbot—it's a reimagining of what browsing can be when AI is the foundation rather than an add-on.
AI-First Architecture: The Core Difference
Comet's intelligent sidebar assistant understands your current page context and can perform multi-step tasks autonomously. Unlike traditional browser assistants that simply answer questions, Comet's AI can actually interact with websites on your behalf—clicking buttons, filling forms, navigating between pages, and synthesizing information across multiple open tabs.
This agentic capability means you can give Comet natural language commands and watch it execute complex workflows that would normally require dozens of manual actions.

Key Features That Set Comet Apart
- Cross-Tab Intelligence: Comet analyzes content across all your open tabs simultaneously, creating comparison tables and synthesizing insights without you switching between windows.
- Email Automation: Summarize email threads, draft contextual responses, manage subscriptions, and organize your inbox through natural language commands integrated directly into Gmail.
- Research Acceleration: Compare products across multiple retailers, compile findings from various sources, and generate comprehensive summaries in seconds rather than hours.
- Smart Scheduling: Create calendar events, schedule meetings, and manage your time through conversational commands without leaving your current workflow.
- Privacy-First Design: Built-in ad blocker and privacy controls ensure your browsing data stays protected while still leveraging AI capabilities.

Frequently Asked Questions About Comet Browser
Yes, as of October 2, 2025, Comet browser is completely free for everyone worldwide with no limitations. This includes all features that were previously exclusive to Max subscribers ($200/month) and the Comet Plus subscription ($5/month). You get full AI assistant capabilities, agentic browsing features, premium publisher content access, and built-in privacy tools without any payment required. There are no hidden tiers, trial periods, or feature restrictions in the free version.
Comet runs on Windows 10 or later, macOS 11 (Big Sur) or later, and most modern Linux distributions. For optimal performance, at least 8GB of RAM is recommended, though 16GB is preferable given Comet's resource usage profile. You'll need approximately 500MB of disk space for the browser installation. A stable internet connection is required for AI features to function, as processing happens through Perplexity's cloud infrastructure.
Comet includes built-in privacy controls and ad blocking by default. According to Perplexity's privacy policy, browsing queries sent to the AI assistant are processed to provide responses but are not used to train models without explicit consent. You can adjust privacy settings to control what data is shared with the AI features. The browser supports standard privacy features like incognito mode, tracker blocking, and cookie management. However, using AI features requires sending page content to Perplexity's servers for analysis—this is fundamental to how agentic browsing works.
Yes, Comet includes import functionality for bookmarks, passwords, browsing history, and settings from Chrome, Firefox, Safari, Edge, and other major browsers. During initial setup, the browser will detect your existing browser installations and offer to import your data. You can also manually import bookmarks later through the settings menu. Extension compatibility varies—Comet doesn't support Chrome Web Store extensions directly, though it includes built-in alternatives for common use cases like ad blocking and password management.
Comet requires an internet connection for AI features to function since processing happens on Perplexity's servers. Basic browsing works offline if you've previously cached pages, similar to any browser. However, the AI assistant, agentic capabilities, cross-tab analysis, and other intelligent features require active internet connectivity. If your internet connection drops, Comet functions as a standard browser but without AI assistance until connectivity is restored.
Comet's AI assistant differs fundamentally from chatbots like ChatGPT because it's designed specifically for browsing tasks and can actually control your browser. While ChatGPT excels at conversation and general knowledge tasks, Comet specializes in web-based automation: clicking buttons, filling forms, comparing information across tabs, and executing multi-step browsing workflows. Think of it as a specialized tool for web productivity rather than a general-purpose AI assistant. Comet can also access current web content in real-time, whereas chatbots typically have knowledge cutoffs.
Perplexity Max subscribers (who were previously the only users with Comet access) now receive additional benefits according to the October 2, 2025 announcement. Max users get a new "background assistant" feature that provides enhanced AI capabilities beyond what free Comet users receive. However, the core Comet browser and its primary agentic features are now available to everyone. Max subscription still provides benefits like unlimited Pro Search queries, advanced AI models, and priority support—Comet access is no longer its exclusive differentiator.
Whether Comet can replace Chrome depends on your specific needs and system resources. Comet excels at research, email management, and complex browsing workflows where AI assistance provides clear value. However, it uses more system resources than Chrome, lacks Chrome extension compatibility, and may occasionally encounter issues with complex automated tasks. If your work involves significant research or comparative analysis, Comet could serve as your primary browser. For lightweight browsing or resource-constrained systems, you might prefer keeping Chrome for casual use while leveraging Comet for AI-assisted tasks.
As of October 2025, Comet is available only on desktop platforms (Windows, macOS, and Linux). Perplexity has not announced official plans for iOS or Android versions. The agentic browsing capabilities that make Comet unique would require significant adaptation for mobile interfaces, so any mobile version would likely differ substantially from the desktop experience. For now, Comet is designed for desktop computers and laptops rather than smartphones or tablets.
Comet's accuracy varies by task complexity. For straightforward automation like summarizing articles, comparing products, or drafting email responses, published reviews indicate generally high accuracy. However, complex multi-step tasks like booking travel or filling detailed forms can result in errors where the AI misinterprets requirements or enters incorrect information. It's advisable to review AI-generated actions before finalizing, especially for tasks involving financial transactions or important commitments. Think of Comet as an intelligent assistant that benefits from supervision rather than a fully autonomous agent.
Comet Plus, previously a $5/month add-on, is now included free for all users. It provides access to premium publisher content from CNN, The Washington Post, Fortune, Los Angeles Times, and publications from Condé Nast. This means you can use Comet's AI to summarize and analyze articles from these premium sources without hitting paywalls. The AI assistant can also cite and reference this premium content when answering your questions, giving you access to higher-quality information sources than typical free search results provide.
Yes, Comet supports multiple user profiles, allowing different family members or work contexts to maintain separate browsing histories, bookmarks, and AI assistant configurations. Each profile can have its own privacy settings, connected accounts (like Gmail), and customized AI behavior preferences. This is particularly useful if you want to separate personal and professional browsing or share a computer with others while maintaining individual browsing experiences and AI training patterns.
The Bottom Line: Should You Switch to Comet?
Perplexity's decision to make Comet completely free represents a significant moment in browser evolution. For the first time, truly agentic AI browsing—capabilities that can automate complex web workflows and intelligently synthesize information across sources—is accessible to everyone without subscription barriers.
Comet is worth trying if you: Spend significant time on research, manage heavy email volumes, frequently compare products or services across websites, or want to automate repetitive browsing tasks. The potential time savings for these use cases may justify the learning curve and resource requirements.
You might want to wait if you: Have a resource-constrained system (under 8GB RAM), primarily do casual browsing without research needs, or require specific Chrome extensions that Comet doesn't support. In these scenarios, traditional browsers may serve you better currently.
The competitive landscape of 2025 shows AI browsers gaining serious traction. With Arc's Dia at $20/month and Chrome adding Gemini Pro features behind paywalls, Comet's free positioning gives it a substantial advantage in market adoption. Having access to cutting-edge AI browsing capabilities at no cost makes Comet worth evaluating in your productivity workflow.
The browser wars have entered a new phase where intelligence matters as much as speed. Comet's release as a free product accelerates this transition and gives everyone access to preview how we'll browse the web in the coming years.
