Perplexity
An answer engine that returns responses with source links you can open.
Tasks: Research Chat and questions
Perplexity publishes its product at perplexity.ai. Official materials describe it as an answer engine that researches the open web and returns replies with citations.
Use the official site for apps, plans, and how citations are presented. This page does not invent accuracy rates.
It is most useful when you need links to follow, not just a fluent paragraph. Open the cited pages before you treat a claim as settled; assistants can still misread or omit context.
