Comet is Perplexity’s AI-powered browser. It blends a fast Chromium base with an agent that can read pages, take actions, and complete tasks for you. It changes how you search, research, and work on the web.
- What Makes Comet Different
Traditional browsers display content and require you to do all the work. Comet integrates an agentic AI that can see your entire browsing context, take autonomous action across websites, fill out forms, click buttons, and maintain memory across conversations. Think of Chrome as a car you drive manually, while Comet is a driver who already knows where you’re going.
- What Makes Comet Useful
Comet see’s your full browsing session. It reads each tab. It connects information across pages. It can click, scroll, fill forms, summarize, and compare content.
You speak or type. Comet executes.
Chrome shows information. Comet completes work.
- Core Capabilities
Conversational Search
Comet returns direct answers with citations. You ask follow-up questions. You verify sources in one place.
Multi-Tab Intelligence
Use @tab to link any tab into your prompt. Type @ to bring up a list of open tabs, then click to reference specific tabs in your query. You reduce copy-paste. You work faster across many pages.
Voice Mode
Use Alt + Shift + V.
You speak natural commands.
Comet carries out long tasks and keeps context active.
Autonomous Actions
Comet can click, type, and move across websites. You give approval when needed. You stay in control.
- Keyboard Shortcuts
These shortcuts work on macOS and Windows. They open the assistant, summarize pages, compare tabs, and control your browser.
Note: Shortcuts may vary between builds. Check Settings > Keyboard Shortcuts in Comet for your current key bindings.

- Important Notes and Limits
Comet is powerful, but you should keep three rules in mind.
Rule 1
Comet asks for approval before sensitive or high-risk actions.
Rule 2
Complex multi-site tasks work better when split into small steps.
Rule 3
Custom slash commands are created by the user. They are not built-in features.
Comet is still a beta product. Expect occasional errors. Always verify critical work.
