ecommerceguide summary

Comet is Perplexity's AI browser with an assistant that researches products, compares options across sites and can place an order on the shopper's behalf, confirming before checkout. It is available for Mac, Windows, iOS and Android, and also reaches shoppers through Perplexity's web and mobile apps. Reporting names Amazon as a retailer it buys from; a US appeals court overturned an injunction blocking that in August 2026.

Why it stands out

Comet is a full browser published by Perplexity for Mac, Windows, iOS and Android, not a sidebar extension.
