When an assistant is acting in a browser, review the intended task and resulting actions before treating them as final.

The public pricing page should be checked for current plan features, usage limits, and any differences between free and paid access.
How people actually use Perplexity Comet
Tab-based research
Bring together information already open across several pages and ask the assistant to work from that browsing context.
