Comet by Perplexity

Overview

Imagine a web browser that doesn’t just show you the internet but actively helps you navigate, understand, and even act upon it. Comet is an AI-infused web browser designed to transform your everyday browsing experience. By integrating instant, context-aware search, automating tedious tasks, and offering seamless integrations, Comet empowers users to summarize content, shop intelligently, and explore new ideas without ever leaving the page. It’s more than just a browser; it’s your intelligent co-pilot for the digital world.

Key Features

Comet is packed with innovative features designed to streamline your online activities and boost productivity. Here’s a closer look at what makes it stand out:

• Unified AI Search: Get instant, context-aware summaries and direct sources right from your address bar, eliminating the need to open new tabs for quick answers.
• Instant Text Highlighting: Simply highlight any text on a page to receive immediate explanations, definitions, or related queries, deepening your understanding on the fly.
• Comet Assistant for Agentic Tasks: This powerful assistant can handle complex, multi-step actions like summarizing emails, efficiently managing your tabs, and automating various online actions, such as adding multiple items to a shopping cart.
• Video and Article Summarization: Quickly grasp the main points of long-form content, whether it’s an article or a video, complete with the ability to ask follow-up questions for deeper insights.
• Cross-Site Automation: Beyond simple tasks, Comet can automate complex workflows across different websites, perfect for research, online shopping, and even scheduling appointments.

How It Works

Getting started with Comet is intuitive and designed for seamless integration into your browsing habits. At its core, Comet simplifies your online experience by bringing AI directly into your browser. Simply open Comet and begin typing your queries directly into the address bar, just as you would with a traditional search engine. However, instead of just links, you’ll receive AI-generated responses, summaries, and direct answers. For deeper interaction, you can highlight any text on a webpage to trigger instant explanations or related queries. Alternatively, invoke the sidecar Comet Assistant to analyze the current page, perform complex tasks, or even navigate autonomously across multiple sites, all while maintaining your user context and preferences.

Use Cases

Comet’s versatile AI capabilities make it ideal for a wide range of everyday and specialized online activities. Here are some practical ways you can leverage its power:

• Research and Analysis: Instantly expand on articles or videos you’re viewing, getting quick summaries and follow-up questions without breaking your flow. The assistant can compare information across multiple tabs and generate comprehensive research reports.
• Automated Workflows: Let Comet handle repetitive tasks such as form filling, data extraction, and multi-step processes across different websites, significantly reducing manual work.
• Enhanced Shopping Experience: Analyze products across different sites, compare features and pricing, and even automate the process of adding items to your cart, making shopping more efficient and informed.
• Content Processing: Quickly digest lengthy emails, meeting notes, calendar events, or any long-form content, saving valuable time and boosting your productivity.
• Contextual Learning: Dive deeper into topics that pique your interest during casual browsing, getting instant explanations and related information without the clutter of opening multiple new tabs.

Pros \& Cons

Like any advanced tool, Comet comes with its own set of advantages and considerations.

Advantages

• Revolutionary browsing speed: AI-powered summaries and instant answers significantly reduce the time spent searching and sifting through results, with users reporting dramatic time savings for complex tasks.
• Advanced agentic capabilities: Automation features handle sophisticated, multi-step workflows across websites, acting as a true digital assistant rather than just a search tool.
• Seamless Chromium integration: Built on Chromium foundation, ensuring compatibility with existing Chrome extensions, bookmarks, and passwords for easy migration.
• Cutting-edge AI integration: Leverages Perplexity’s powerful AI engine for accurate, context-aware responses with real-time web information.

Disadvantages

• Premium pricing barrier: Requires expensive Perplexity Max subscription at \$200 monthly or \$2000 annually, significantly limiting accessibility compared to free alternatives.
• Privacy considerations: Deep AI integration requires extensive data access and processing, which may raise concerns for privacy-conscious users.
• Early adoption risks: As a newly launched product, users may encounter stability issues and feature limitations compared to mature browsers.
• AI reliability limitations: Like all AI systems, occasional inaccuracies in responses and analysis are possible, requiring user verification for critical tasks.

How Does It Compare?

So, how does Comet stack up against the competition in the rapidly evolving AI browser landscape of 2025?

Versus Traditional Browsers

Compared to traditional browsers like Chrome and Safari, Comet represents a fundamental shift in browsing philosophy. While Chrome offers robust performance and extensive extension support, Comet integrates built-in agentic AI for automation and context-aware interactions directly into its core. This eliminates the need for multiple extensions and reduces tab switching, transforming the browser from a simple web viewer into an intelligent workspace assistant.

Versus AI Browser Competitors

The AI browser space has become intensely competitive in 2025, with several major players:

Microsoft Edge Copilot Mode launched in July 2025, offers integrated AI assistance with voice commands and task automation, backed by Microsoft’s enterprise ecosystem and free accessibility for existing Edge users.

Arc’s Dia Browser from The Browser Company represents an AI-first approach with proactive suggestions and contextual memory, currently in invite-only beta with focus on productivity workflows.

Opera Aria provides local AI model support and extensive customization options, appealing to users who prefer on-device processing and privacy control.

Upcoming OpenAI Browser rumored for release, would integrate ChatGPT directly into browsing experience, potentially offering the strongest natural language processing capabilities.

Comet’s key differentiator lies in its sophisticated agentic automation capabilities and Perplexity’s proven track record in AI search accuracy. However, its premium pricing model contrasts sharply with free alternatives like Edge Copilot, potentially limiting its market reach despite superior functionality.

Final Thoughts

Comet represents a significant advancement in AI-powered browsing, offering genuinely transformative capabilities for users willing to invest in premium AI tools. Its autonomous task execution, cross-site automation, and intelligent content analysis showcase the future potential of browser technology. However, the substantial \$200 monthly subscription requirement and privacy considerations mean it’s primarily suited for professionals, researchers, and organizations where time savings justify the cost.

While Comet excels in sophisticated automation and AI integration, users should carefully evaluate whether its advanced features warrant the premium price compared to emerging free alternatives like Microsoft Edge Copilot Mode. As the AI browser wars intensify throughout 2025, Comet’s success will likely depend on demonstrating clear ROI for its target professional audience while potentially introducing more accessible pricing tiers for broader adoption.

For organizations and individuals seeking cutting-edge AI assistance in their daily web workflows, Comet offers unparalleled capabilities. For general users, waiting for the competitive landscape to mature and prices to stabilize may be the more prudent approach.
