What is Perplexity?

Perplexity combines LLMs with real-time search, citing sources for every claim.

Our take

Perplexity is the AI search engine that cites its sources. For research, current events, and product decisions, it is dramatically faster than Google + opening 10 tabs. The free tier gives 3 Pro searches per day, the Pro plan at $20/month adds unlimited Pro searches, file upload, and the focus mode for academic/Reddit/news sources. Best for: anyone who does research, journalists, students, investors.

Example

Our verdict

Pick Perplexity if: Perplexity is the right pick if you do regular research - whether that is for work, investing, or academic purposes. The cited sources mean you can trust the output, the Pro Search handles complex multi-step research in one prompt, and the $20/month Pro plan is the right pick for anyone who does more than casual research.

Skip Perplexity if: If you only need a general assistant, ChatGPT Plus is more well-rounded. If you need the deepest multimodal capabilities, Gemini is the better pick. Perplexity is a research tool, not a general assistant.
