Comet – An AI-powered browser that automates tasks and remembers context across tabs.

Comet is a next-generation browser developed by Perplexity that transforms the web browsing experience into an intelligent, AI-assisted workflow. It moves beyond being a passive window to the internet by incorporating agent-driven functionality that actively helps with complex, multi-step tasks. This positions Comet as a powerful tool for professionals and teams looking to enhance productivity and streamline digital operations.

By retaining context across tabs and sessions, Comet reduces cognitive friction, making it ideal for users engaged in research, scheduling, and content management. It is part of a growing category of AI automation tools designed to save time and improve efficiency.

What is Comet?

Comet is an intelligent browser that acts as an active participant in your online work. It automates tedious processes like product research, meeting coordination, and email triage by understanding your intent and executing sequences of actions. Unlike traditional browsers, Comet maintains a memory of your activity, allowing you to pause and resume complex workflows without losing your place or re-entering information.

It is designed for founders, developers, researchers, and product teams who need to synthesize information from multiple sources quickly. Its core value lies in turning the browser from a tool for viewing into a tool for doing, making it particularly powerful for in-depth research and project management.

Key Features

• Agentic Task Automation: Executes multi-step actions like product research and purchase, meeting scheduling, and inbox management.

• Cross-Tab Context Awareness: Maintains memory and understanding across different tabs and browsing sessions.

• Integrated AI Assistant: Provides direct assistance and answers within the browser interface.

• Workflow Simplification: Reduces the need to switch between multiple apps by handling tasks in a unified environment.

Use Cases

• Competitive Analysis: Automatically gathering and comparing product features, pricing, and reviews from multiple websites.

• Executive Assistance: Scheduling meetings by finding mutual availability, booking slots, and sending calendar invites.

• Academic Research: Compiling sources, extracting key points, and summarizing findings from journal articles and databases.

• E-commerce Management: Researching products, tracking price drops, and automating purchase workflows.

Underlying AI Models or Technology

Comet leverages advanced natural language processing models to understand user intent, parse web content, and generate appropriate actions. Its ability to maintain context suggests the use of large language models (LLMs) with extended memory or retrieval-augmented generation (RAG) techniques. The core functionality relies on complex question answering and agentic reasoning to break down user requests into executable steps across the web.

Pricing

Comet is a paid application. Specific pricing tiers and subscription details are available directly from the official Perplexity website. The pricing model is typically structured to cater to individual professionals, teams, and enterprise clients, with features scaling accordingly.

Pros and Cons

Pros

• Significantly reduces time spent on repetitive, multi-step online tasks.

• Unique context memory across sessions eliminates friction in long workflows.

• Integrates directly into the browsing experience, requiring minimal setup or app switching.

Cons

• As a paid tool, it may not be accessible to all users or for casual needs.

• Automation accuracy is dependent on the AI's interpretation of complex or ambiguous requests.

Alternatives

For users seeking different approaches to browser automation or AI assistance, several alternatives exist. These range from browser extensions that add specific automations to standalone AI agent platforms that operate outside the browser.

• Arc Browser: A modern browser focused on workspace organization and spatial management, with some integrated AI features.

• Zapier or Make: Platform-agnostic automation tools that connect web apps and can automate tasks between them, though not natively within a browser.

• AI Chatbot Extensions: Browser add-ons that provide conversational AI assistance on any webpage but lack deep workflow automation.
