About Comet
Comet is a browser from Perplexity, the AI search company. It is built on Chromium, so it supports most Chrome extensions, bookmarks and page translation, and it uses Perplexity as the default search engine. Its main feature is the Comet Assistant, which sits beside the page and can summarise what you are reading, answer questions across open tabs, and carry out tasks such as filling in forms, comparing products or managing email and calendar, depending on permissions you grant. The browser is free to use, with more capable models and higher limits for Perplexity's paid subscribers, and enterprise versions with admin controls exist. As with any agent browser, letting AI act on websites has security and accuracy risks, and pages you visit are processed by Perplexity's services. It is available for Mac, Windows, iOS and Android. It suits people who already use Perplexity and want AI research and task help built into their browser.
Best for: Perplexity users who want AI research and task help built into their browser.
