Comet Browser
What it is
Comet is a web browser built by Perplexity on Chromium, so it supports most Chrome extensions, bookmarks and page translation. Perplexity search is the default engine, and the Comet Assistant sits alongside every page to answer questions, compare sources, draft emails, build study plans or carry out multi-step tasks such as shopping research. Other features include natural language commands for tab management, a summarize button, personal search across your browsing history, a Gmail connector for email and calendar questions and a built-in ad blocker. Comet first launched in limited release in July 2025 and became free to download in October 2025, with apps for Mac, Windows, iOS and Android.

Editor's notes
More context from AI BirdView
Comet takes Perplexity's answer engine and makes it the center of the browsing experience. Instead of copying text into a separate chat window, you can ask about the page you are on, have the assistant compare coverage across sources or hand it a task that spans several sites. Because it is built on Chromium, switching from Chrome feels familiar.
- The assistant can summarize long pages, answer follow-up questions and act on content in context.
- Tab management works through plain language commands, which helps when research sessions sprawl.
- Personal search can surface pages from your own browsing history when you cannot remember where you saw something.
- A Gmail connector lets you ask about email and calendar items from the browser.
- Perplexity offers dedicated help pages for enterprise installs and assistant permission controls.
Comet is best for students, researchers and knowledge workers who spend most of the day reading and comparing information online. A practical tip: review the Comet Assistant permission settings before letting it act on sites where you are signed in, and keep sensitive tasks such as payments under your own control.
