What is Perplexity?

Perplexity is an answer engine rather than a chatbot. Every answer is retrieved from live web results and arrives with inline citations, so you can check any claim against the page it came from instead of taking the model's word for it. It reformulates vague questions, runs several searches behind the scenes and then synthesises a direct answer with supporting links. That combination makes it genuinely useful for research, competitive analysis and fact-checking - places where a plain chatbot's confident guesses are a liability.

FAQ

How is Perplexity different from ChatGPT?

Perplexity retrieves from the live web by default and cites its sources on every answer. ChatGPT generates from model knowledge unless browsing is enabled, so its unsourced claims are harder to check.

Can I trust Perplexity's answers?

Trust the citations rather than the summary. Perplexity is far more reliable than an uncited chatbot precisely because it shows its sources, but the answer is only as accurate as the pages it cites.

Is there a free version?

Yes. The free tier handles normal searches and allows a limited number of deep-research queries per day, which is enough for casual use.
