Frequently asked questions

How is Perplexity different from Google?

Rather than showing a list of links, Perplexity reads the relevant pages and writes a concise answer that cites its sources. You save time while keeping the ability to verify every piece of information.

Are the answers reliable?

The systematic citations greatly limit fabrications, but it is still recommended to check the sources for sensitive topics or important decisions.

Is there a free version?

Yes, standard search is free and unlimited, as is the Comet browser. The Pro plan adds a high volume of advanced searches and access to the best models.
