Comet by Perplexity
An AI-powered web browser from Perplexity with a built-in assistant that can research and act on pages.
What is Comet by Perplexity?
Comet is a web browser from Perplexity with an AI assistant built in. It can summarize what you're reading, answer questions across your open tabs and carry out tasks on websites, such as filling forms or comparing products.
Comet launched in 2025, first for Perplexity's top-tier subscribers, and was later opened up as a free download. It is built on Chromium, so it supports familiar extensions and feels like a standard browser.
The difference is the assistant in the sidebar. You can ask it to explain a page, pull key points from a long article, compare options across tabs or take an action for you.
Agentic features let Comet navigate sites and complete multi-step tasks, which is where it overlaps with other browser agents.
As with any browser agent, be careful when it acts on logged-in accounts, and review actions before anything is purchased or sent.
