The internet has fundamentally changed how we work, learn, and connect. Yet for decades, web browsers have remained largely unchanged—until now. Perplexity AI’s Comet Browser, which launched to the public in October 2025 after a limited release that began in July, represents a revolutionary approach to web browsing powered by artificial intelligence.
In this comprehensive guide, we’ll explore everything you need to know about Comet Browser, from its groundbreaking features to pricing, security considerations, and whether it’s the right choice for your browsing needs.
What is Comet Browser?
Comet Browser is the first truly agentic browser, meaning you can not only interact with its built-in AI assistant (Perplexity), but it can actively engage with your tabs, emails, calendar, and even navigate the web autonomously on your behalf.
Think of it as having a personal digital assistant embedded directly into your browser—one that can see what you’re seeing, understand your questions in context, and take meaningful action to help you accomplish tasks faster than ever before.
Comet combines the search capabilities of Google, the conversational intelligence of ChatGPT, and task-assistance features similar to Notion AI—all integrated into a single, streamlined browsing experience.
Key Features That Set Comet Apart
1. AI-Powered Sidecar Assistant
Comet’s primary feature is a sidecar assistant that accompanies you while browsing, helping answer questions about web pages, summarize content, manage web information, and navigate pages on your behalf.
The assistant understands context from your current webpage, making it incredibly powerful for:
- Instant explanations of complex topics
- Quick summaries of lengthy articles
- Answering questions about video content
- Extracting key information from documents
2. Agentic Browsing Capabilities
The assistant can actually navigate around pages, open new pages when necessary, and take actions as if it were a human performing tasks for you. This means you can:
- Ask it to find deals across multiple websites
- Request summaries of YouTube videos without watching
- Have it research topics across various sources
- Potentially book reservations or complete transactions
This “agentic browsing” represents a fundamental shift from passive web browsing to collaborative, AI-assisted navigation.
3. Email and Calendar Integration
Comet can connect with your Gmail and Google Calendar, providing read/write access that enables the browser to answer questions about your email, upcoming events, and schedule. This integration allows for:
- Quick email summaries and priority identification
- Schedule awareness for booking and planning
- Context-aware assistance based on your commitments
- Automated task management
4. Tab-Aware Intelligence
Unlike traditional browsers where each tab exists in isolation, Comet’s assistant can see and interact with all your open tabs. This enables:
- Cross-tab comparisons and analysis
- Consolidated research from multiple sources
- Intelligent tab organization and management
- Context switching without losing your train of thought
5. Native Perplexity Search Integration
Comet features Perplexity’s AI search engine pre-installed and set as the default, giving you instant access to AI-powered search that provides direct answers with source citations rather than just a list of links.
Pricing: From Premium to Free
Comet Browser initially launched in July 2024 exclusively for Perplexity Max subscribers at $200 per month—one of the most expensive browser offerings ever introduced. However, the pricing landscape has changed dramatically.
Current Pricing Model (October 2025)
As of October 2, 2025, Perplexity released Comet Browser to the public worldwide completely free of charge, after millions joined the waitlist. This represents a massive shift in strategy and makes cutting-edge AI browsing accessible to everyone.
Freemium Structure
Comet follows a freemium model similar to Perplexity’s core search product, offering:
- Free Tier: Core browsing features, AI assistant, basic integrations
- Premium Tiers: Enhanced capabilities, priority support, advanced features
For paid subscribers, Perplexity has also launched a new “background assistant” feature that provides additional proactive assistance.
Who Should Use Comet Browser?
Ideal Users
Comet particularly appeals to early adopters comfortable with products that may have rough edges but offer powerful features few others have experienced. The browser is perfect for:
Researchers and Students: The ability to quickly summarize articles, extract key information, and synthesize data from multiple sources makes research exponentially faster.
Content Creators: Understanding video content, analyzing competitor websites, and gathering inspiration becomes streamlined with AI assistance.
Busy Professionals: Email management, calendar awareness, and automated web navigation help maximize productivity.
Tech Enthusiasts: If you were an early adopter of ChatGPT or Perplexity, Comet offers the next evolution in AI-assisted computing.
Knowledge Workers: Anyone who spends significant time researching, reading, and processing online information will benefit from Comet’s capabilities.

Who Might Want to Wait
While innovative, Comet may not be ideal for:
- Users who prioritize maximum privacy and minimal data sharing
- Those who prefer traditional, established browsers
- People who don’t frequently engage with AI tools
- Users requiring specific enterprise-level browser management
Comet Browser vs. Traditional Browsers
How It Compares to Chrome, Safari, and Firefox
Traditional browsers are essentially windows to the internet—passive tools that display web content without understanding or assisting with it.
Comet Browser actively participates in your browsing experience:
- Understands context across all your tabs
- Can answer questions about any content you’re viewing
- Takes autonomous actions based on your requests
- Integrates with your productivity tools
Comet vs. Other AI Browsers
Perplexity’s decision to make Comet free positions it to compete against both incumbents like Google Chrome and newcomers like The Browser Company’s AI-powered browser Dia.
vs. Dia Browser: Both offer AI integration, but Comet focuses heavily on agentic capabilities and Perplexity’s search prowess, while Dia emphasizes different AI interactions.
vs. Arc Browser: Arc revolutionized browser UI/UX, while Comet revolutionizes browser intelligence and capability.
vs. Brave/Edge with AI: While these browsers have added AI features, they’re retrofitted onto existing architectures. Comet was built AI-native from the ground up.
Real-World Use Cases

Imagine researching climate change. With Comet, you can:
- Open multiple academic papers in different tabs
- Ask the assistant to compare methodologies across studies
- Request summaries highlighting contradictory findings
- Generate a consolidated understanding without reading every page
E-Commerce and Shopping
When shopping for electronics:
- Open product pages across multiple retailers
- Ask Comet to compare specifications side-by-side
- Request it to find the best current deals
- Have it identify the optimal purchase option based on your criteria
Content Consumption
For YouTube videos, podcasts, or long-form articles:
- Ask for key points without consuming the entire content
- Request specific information (“What did they say about inflation?”)
- Get instant explanations of complex concepts mentioned
- Jump to relevant sections based on your interests
Productivity and Email Management
Managing your workflow:
- Ask about important emails without opening your inbox
- Check your schedule for the week ahead
- Find times for meetings automatically
- Get summaries of long email threads
Important Security Considerations
The CometJacking Vulnerability
A significant security issue called “CometJacking” was recently discovered, where a single malicious URL can hijack Comet AI browser through encoded payloads that exploit URL parameters, potentially exfiltrating emails, calendar data, and user memory.
What This Means: Attackers could craft special URLs that, when clicked, give hidden instructions to Comet’s AI assistant to access and steal sensitive information from your connected services.
Perplexity’s Response: As this vulnerability was just discovered, users should:
- Be cautious about clicking unfamiliar links while using Comet
- Monitor for security updates from Perplexity
- Consider waiting for the patch if dealing with highly sensitive information
Context: This vulnerability highlights the security challenges inherent in browsers that have deep integrations with personal data. All new technologies face security scrutiny, and responsible disclosure helps make products safer.
