Perplexity的Comet功能 （ai回答）

 Comet is an AI-powered web browser launched by Perplexity AI that fundamentally transforms how users interact with the internet by integrating artificial intelligence at its core123. Unlike traditional browsers that treat AI as an add-on, Comet embeds AI deeply for seamless, context-aware browsing and task automation.

Key features of Comet include:

• Comet Assistant: An AI agent integrated into a sidebar that can see and understand the content of any active webpage. It allows users to ask questions, get instant summaries of articles, analyze text in documents, and interact with content like YouTube videos without switching tabs or copy-pasting124.

• Automated Workflows: Users can request Comet to perform complex tasks such as booking meetings, sending emails, managing tabs, or making purchases on their behalf, collapsing multiple steps into fluid, conversational interactions14.

• Perplexity Search Engine Integration: Comet uses Perplexity’s AI search engine as the default, providing AI-generated summaries and answers directly within the browser, enhancing research and decision-making processes123.

• Built on Chromium: Comet offers compatibility with existing Chrome extensions and allows seamless import of bookmarks and settings. It also includes a built-in ad blocker prioritizing user privacy13.

• Privacy and Local Processing: Sensitive tasks like calendar management can be processed locally on the device, with multiple tracking modes for user privacy1.

• Availability: Currently, Comet is exclusive to subscribers of Perplexity’s $200/month Max plan and is rolling out gradually to waitlisted users. It is available on Windows and macOS, with plans to support more platforms including mobile in the future1234.

• Strategic Vision: Perplexity positions Comet as a "cognitive operating system" that shifts web interaction from simple navigation to thoughtful cognition, reducing context switching and enabling users to “think out loud” while the AI executes tasks14.

Comet aims to challenge established browsers like Google Chrome by embedding advanced AI directly into the browsing experience and offering deeper task automation and personalization than typical browsers13. CEO Aravind Srinivas envisions Comet as a platform that enables "infinite retention" by becoming the default tool through which users conduct their digital lives.

In summary:

Comet represents Perplexity’s strategic move to redefine internet browsing by integrating intelligent AI assistance that enhances productivity, understanding, and decision-making in everyday web interactions124.
