Group: Errands, travel and food

Comet is Perplexity's browser, available for Mac, Windows, iOS and Android. The vendor page shows an assistant that answers questions about what you are reading, drafts email replies, builds simple sites, makes study plans and shops, and Perplexity's pricing page lists a Comet Agent and Comet Assistant among plan features.

The decision in plain English

Perplexity says the Comet browser is free to download for everyone (its blog post is dated 2 Oct 2025). Its pricing page lists Free at $0, Pro at $20 a month and Max at $200 a month, with the stronger models behind Comet Assistant and Comet Agent listed under the paid plans; Max adds a 'Max Assistant' mode on Comet per the vendor help centre.

Best fit

People who want an AI assistant inside the browser to read, summarise, draft and shop, and who are comfortable giving a browser assistant access to their sessions.

Poor fit

Anyone who needs the exact free-versus-paid Comet limits: the vendor pages we checked do not spell out which agent actions the free tier allows.
