What Is Comet Browser by Perplexity?
Comet Browser is an AI-native web browser developed by Perplexity, integrating conversational AI directly into the browsing experience. At its core is the Comet Assistant, a built-in agent that can interact with web content, tabs, email, and calendars. Rather than just helping you search, it can perform actions on your behalf, navigating websites, summarizing content, and managing digital tasks much like a human assistant.
What makes Comet distinct is its focus on what Perplexity calls “agentic browsing.” This concept redefines how users interact with the web: instead of clicking and navigating manually, users can ask the assistant to carry out tasks across the web, effectively letting it “drive” the browser. This model is primarily aimed at early adopters and power users who are already familiar with AI tools like Perplexity and ChatGPT.

Key Features and Capabilities of Comet Browser
1. Comet Assistant Integration
At the heart of Comet Browser is its built-in assistant, which provides AI-driven research and navigation. Unlike traditional AI tools that just return information, Comet Assistant can interact with open tabs, filter searches based on your active browsing context, and even act on web content, clicking links, opening new tabs, and executing multi-step tasks.
2. Agentic Browsing Capabilities
Comet introduces an agentic browsing experience. Users can give high-level commands like “book a flight” or “find a summary of this video,” and the assistant will take the necessary steps, visiting sites, extracting information, and performing actions without the user needing to manually click through each step.
3. Voice Assistant
The browser supports a voice-based interface, allowing users to speak directly to the assistant. You can ask questions about the current page, request actions across open tabs, or perform searches across the internet, all through natural conversation. This creates a more fluid and hands-free experience, especially for research or multitasking.
4. Email and Calendar Integration
Comet connects to your Gmail and Google Calendar with read/write access, enabling it to answer questions about your schedule or recent emails. This integration lets the assistant perform context-aware tasks like scheduling meetings or finding information buried in your inbox.

PC Magazine
Review Summary:
Visually, Comet offers a polished and modern interface. The assistant’s sidebar integration feels more cohesive compared to competing tools that rely on pop-out windows. Widgets on the home page add light customization options, and shortcuts make recurring tasks more efficient. However, PCMag notes that these features are more about convenience than transformative functionality.
That said, performance and limitations are still major concerns. AI-driven actions like shopping cart automation often fail or are slower than manual browsing. Voice mode, while promising, underperforms compared to text-based interaction. Additionally, the browser consumes significant system resources when AI features are active, and its Perplexity-based search engine sometimes lags behind Google in result relevance.
Despite its flaws, Comet offers promising AI-native features that could appeal to early adopters. While it’s not yet a browser that will radically change most users’ workflows, it presents a credible alternative for those seeking to move away from Google without giving up Chromium compatibility.
Verdict
Comet Browser stands out for its innovative AI assistant and customizable shortcuts, making it a potential asset for power users. However, its inconsistent agentic features and performance overhead keep it from being a mainstream Chrome replacement today. For now, it’s best viewed as a forward-looking experimental tool—promising, but not essential unless you’re eager to explore the future of AI-driven browsing.
The Verge
Review Summary:
Unlike AI tools added onto existing browsers, Comet was built from the ground up to function with an integrated assistant that “travels the web with you.” The assistant is designed to help users handle routine digital tasks like shopping, travel planning, and managing life’s logistics—potentially replacing manual browsing with delegated AI action.
Perplexity is also expanding the browser’s capabilities through Comet Plus, a premium content bundle included with Pro and Max subscriptions (or available for $5/month). This offering gives users access to news from major outlets such as CNN, Fortune, and The Washington Post, mirroring services like Apple News Plus.
The broader context is that Comet is just one of several AI-native browsers vying for relevance. While Chrome now features Gemini, and other browsers like Arc and Opera Neon are exploring their own AI integrations, Comet differentiates itself by making AI the core experience—not just an add-on.
Verdict
The Verge’s coverage positions Comet as an ambitious attempt to reimagine how users interact with the web—by embedding AI at the foundation rather than as an overlay. Its transition from a premium product to a free tool for the masses marks a strategic pivot to drive broader adoption. With built-in task automation and premium news integration, Comet has the potential to reshape daily browsing, but it now faces growing competition from tech giants and browser startups alike.
LifeHacker
Review Summary:
Comet stood out for its clean design and accessible AI features, including article summarization, voice interaction, and a sidebar assistant that remains ready to act. The assistant could perform simple tasks like replying to Gmail threads or creating Google Keep notes, and it displays the steps it takes in real-time, giving users some transparency into its decision-making.
While Comet showed promise in handling routine digital chores, Lifehacker noted that it can stumble over more complex web interfaces. The browser does try to resolve issues as they come up, but it isn’t always reliable. As with other AI browsers, privacy and control remain concerns, especially since these tools track activity to support ongoing tasks.
Overall, Comet offers a polished and functional AI experience, especially now that it’s available for free, but its agentic capabilities are still evolving and should be used with caution.
Verdict
Lifehacker views Comet as a capable early entrant in the AI browser space. It delivers solid usability, especially for quick tasks and summarization, and integrates AI into the browsing experience more cleanly than most. However, the tech isn’t flawless: its agentic features can misfire, and privacy remains a critical question. While not ready to fully automate browsing, Comet is a practical, forward-looking tool for those curious about the next phase of web interaction.
