Comet

Comet is an AI-powered web browser built by Perplexity AI on the Chromium platform. It launched in July 2025 for Windows and macOS, with Android support added in November. The browser solves the problem of fragmented browsing workflows by integrating agentic AI assistance directly into web navigation.

Features

• Built-in AI Assistant: Integrated Perplexity engine with access to multiple LLMs including GPT-5, Claude 4, Gemini Pro, and Grok 4 for conversational search and task execution.
• Cross-Tab Context Awareness: The assistant reads and synthesizes information across multiple open tabs to answer queries without manual tab switching.
• Gmail and Calendar Connectors: Direct integration with Google services allows email organization, scheduling, and inbox management through natural language commands.
• Spaces Organizational Feature: Users can create dedicated browser areas for specific projects with saved threads, notes, and related pages grouped together.
• Native Ad Blocker and Chrome Extension Support: Built-in distraction blocking with compatibility for most Chrome extensions, bookmarks, autofill, and password management.

Use Cases

• For Researchers: Multi-tab summarization and citation gathering across academic sources eliminates repetitive copy-paste workflows during literature reviews.
• For Travel Planners: The assistant searches multiple airline websites simultaneously with specific constraints like aircraft type and connection limits to find optimal flights.
• For Students: One-click webpage summaries, selected text explanations, and study plan generation from syllabus documents streamline learning workflows.
• For Professionals: Automated email drafting, competitor research compilation, and LinkedIn job search assistance reduce time spent on routine tasks.

Comet represents an early attempt at agentic browsing where AI executes complete workflows through natural language. Free tier available with premium features at $200/month through Perplexity Max subscription.
