Comet

Comet is an AI-powered browser from Perplexity that deeply integrates Perplexity's AI search engine and intelligent assistant into the browsing experience, letting users get instant AI assistance while browsing the web for a 'thinking-speed' browsing experience. Built on Chromium and positioned as a 'knowledge synthesis engine', it focuses on organizing, analyzing, and providing cited information, especially suited to research and deep learning scenarios.

• AI assistant sidebar: The smart assistant, summoned with the Alt+A shortcut, understands everything in the browser, providing instant summaries of pages, videos, PDFs, and social media content, with natural language questions and conversational interaction
• Task automation: As a true AI agent, it can execute complex tasks like opening email, scheduling meetings, analyzing calendars, and managing tabs, completing cross-site operations automatically from natural language commands
• Integrated search engine: Perplexity serves as the default search engine, providing AI-driven results with citations, while a shortcut switches back to traditional Google search
• Chrome compatibility: Fully compatible with all Chrome extensions, supports importing bookmarks, history, cookies, and passwords, keeping the familiar browsing experience

In real-world scenarios, researchers can use Comet to gather information across multiple open tabs, documents, and web pages and get a unified, cited synthesis; content creators can use one-click summaries to quickly extract the core of long articles and videos; professionals can let the AI assistant automatically manage email, find important unanswered messages, and schedule meetings, significantly cutting repetitive work.

Comet's core advantage is turning AI from a passive query tool into an active browsing partner—it doesn't just answer questions, it executes tasks independently. Compared with competitor ChatGPT's Atlas, Comet focuses more on 'knowledge synthesis' than 'task execution', emphasizing information integration for research scenarios. Comet is now free for users worldwide, desktop only, with mobile under development.
