Perplexity

Perplexity is built around a simple idea: instead of returning ten blue links, answer the question and show exactly where each claim came from. Every response includes inline citations, and the interface keeps the source list visible so you can check the underlying pages.

It supports focused modes that steer the search — web, academic papers, community discussions and more — plus file uploads for analysing your own documents. Threads can be organised into Spaces, and paid plans add deeper multi-step research reports and higher usage limits. The product sits between a search engine and a chatbot, and is most useful when you want a fast, sourced overview rather than a long conversation.

Citations reduce risk but do not eliminate it: sources can be misread or outdated. Open the key links before acting on a claim.
