Perplexity
Answer engine for research questions, source-backed summaries, and quick topic exploration.
Editor's take
Perplexity is best understood as an answer engine, not a chatbot: you ask a question, it gives you a synthesized answer with links, and the links are the point. It is a strong instrument for the early, exploratory phase of research — getting oriented on a topic, doing competitor scans, understanding a concept before you read the primary material.
Its discipline writes itself: open the sources. The summary is a map, not the territory, and for anything that affects a decision — pricing, policy, a product capability — you want to read the cited page yourself. Reach for Perplexity when the job is "help me understand and find," and switch to a writing-focused tool when the job becomes "help me produce."
