Perplexity Comet is a web browser from Perplexity with a built-in AI assistant that can answer questions about pages and carry out browsing tasks for you.
In plain words
In a normal browser you do every click yourself. Comet adds an assistant that can run whole browsing sessions for you while you get on with something else. You can ask it about the page you are on, have it compare what you are reading with something you read earlier, or hand it chores such as sorting your inbox, ordering groceries or planning a trip. Perplexity launched it on 9 July 2025, and it runs on Mac, Windows, iOS and Android.
A quick example
Imagine you are looking at a bike on a shop's website. You ask the assistant which other sites sell the same bike with faster delivery, and it searches and compares them for you instead of you opening a dozen tabs.
Where you'll meet it
- Research and comparison across many web pages.
- Delegating routine web chores such as email or shopping.
