What Is Perplexity AI?
Perplexity AI is an AI-powered search engine that answers questions using real-time web data with source citations. Unlike ChatGPT, every answer includes links to the original sources so you can verify information. It also offers Deep Research — a feature that autonomously researches a topic and produces a detailed cited report.
Honest Review
Perplexity is the best tool for research requiring up-to-date cited answers. The free tier with ~5 Pro searches per day is genuinely useful for casual research. Pro at $20/month ($200/yr) is exceptional value for anyone who researches daily — 20 Deep Research queries per day alone justifies the cost. Students and educators get the same Pro features at $10/month, while the $200 Max tier adds unlimited Labs and agentic features for power users.
