Comet is a free AI web browser from Perplexity with a built-in assistant that can summarise pages, answer questions about what you are reading and complete multi-step tasks on websites for you. It runs on Windows, Mac, iOS and Android. The browser is free, and Comet Plus costs $5 a month.
What is Perplexity Comet?
Comet is a Chromium-based browser with Perplexity’s AI built in. Instead of switching between tabs and a chatbot, you open the Comet Assistant in a sidebar and ask about the page you are on, compare tabs or get a quick summary of a long article or video.
Its agent can also act for you: it can navigate websites, fill in forms, collect information and run multi-step tasks while you watch. Because it is built on Chromium, it supports Chrome extensions and can import your bookmarks and passwords.
