Perplexity AI has launched Comet, a revolutionary AI-powered web browser that transforms traditional browsing into an intelligent, task-aware experience. As of October 2025, Comet is now freely available to all users worldwide, marking a significant shift in how we interact with the internet. This comprehensive guide explores everything you need to know about Comet—from its core features and availability to compatibility and advanced capabilities.
What is Perplexity Comet?
Comet is a Chromium-based browser that integrates advanced AI capabilities powered by Perplexity's search engine and multiple large language models, including Sonar, GPT-5, Claude 4, and Gemini Pro. Unlike traditional browsers that simply display websites, Comet acts as an intelligent companion that can understand context, automate tasks, and execute actions on your behalf.
The browser represents a new paradigm called "agentic browsing," where the AI assistant doesn't just respond to queries but actively performs multi-step tasks across tabs and websites. Think of it as having a personal research assistant embedded directly into your browser—one that can summarize articles, compare products, draft emails, book meetings, and navigate websites autonomously.
Key Features and Capabilities
AI-Powered Comet Assistant
At the heart of Comet lies the Comet Assistant, accessible via a sidebar interface that accompanies you throughout your browsing. This AI agent can:
Answer contextual questions about open pages without switching tabs
Execute natural language commands like "close all tabs" or "reopen the podcast I was viewing yesterday"
Automate complex workflows including sending emails, scheduling meetings, and making purchases
Navigate websites autonomously by clicking, scrolling, and interacting with web elements on your behalf
The assistant understands context across multiple open tabs, enabling sophisticated comparisons and cross-referencing that standalone AI tools like ChatGPT cannot achieve.

Workspace Management and Organization
Comet replaces traditional tab chaos with an intelligent workspace model. You can:
Group related tabs into dedicated workspaces based on projects or research topics
Ask Comet to organize tabs automatically by analyzing their content and creating relevant workspaces
Resume research projects by simply selecting the appropriate workspace from the navigation bar
Access Perplexity Spaces directly from the assistant by typing @ followed by your custom space name
This organizational approach significantly reduces information overload and helps maintain focus during complex research tasks.

Privacy and Security Considerations
Data Collection and Storage
Comet employs a hybrid architecture that balances local processing with cloud-based resources:
Stored Locally on Your Device:
Browsing history, URLs, cookies, and site permissions
Open tabs, search queries, and download records
Extensions, passwords, payment methods, and bookmarks
Cloud Processing:
Complex queries requiring up-to-date information are routed through Perplexity's API
When you ask context-specific questions, a limited amount of relevant session data is sent to Perplexity's servers
The browser automatically switches between local and cloud modes based on network latency, model size requirements, and data sensitivity
Privacy Controls
Comet offers several privacy features:
Built-in ad blocker for cleaner browsing
Local-Only Mode for sensitive operations like health queries or document analysis
Incognito Mode prevents collection of browsing data and download records
User-controlled data deletion from query history at any time
Privacy mode that restricts cloud interaction "as much as possible"
Security Concerns
Despite these protections, privacy-conscious users should be aware of certain limitations:
Comet collects data to improve AI functionalities and potentially target ads
The browser's deep integration allows continuous monitoring of browsing activity
Security researchers have identified indirect prompt injection vulnerabilities where malicious webpage content can trick Comet into executing unintended actions
The vague phrase "as little as possible" regarding cloud interaction doesn't guarantee complete data security
