Perplexity AI
AI answer engine that searches the web and cites sources
About this agent
Perplexity is an AI-powered answer engine. Instead of handing you a page of blue links to sift through, you ask a question in plain language and get a clear, written answer — with numbered citations to the exact sources it used, so you can trust and verify every claim.
What it does
- Direct answers, with sources. Every response links to the websites, papers, and articles behind it.
- Real-time web access. It searches the live internet, so answers reflect what is true today — not last year.
- Focus modes. Point your search at academic papers, coding help, YouTube, Reddit discussions, or the whole web.
- Natural follow-ups. It suggests smart next questions and keeps the thread, so research feels like a conversation.
- Pro Search & Assistant. Deeper multi-step research, plus an agent that can browse, compare options, and complete tasks for you.
Who it is for
Students, researchers, writers, developers — and anyone tired of opening ten tabs to answer one question. If you value accuracy and want to see where information comes from, Perplexity is built for you.
How people use it
- Researching a topic quickly with trustworthy citations.
- Comparing products, tools, or options side by side.
- Summarizing long articles, papers, and documents.
- Getting up to speed on news and current events.
There is a generous free plan, with a Pro subscription that unlocks more powerful models and deeper research.
Why it was built
Search has not really changed in twenty years — you still get a page of links and have to do the synthesis yourself. Perplexity was built to hand you the answer directly, with sources you can verify, so research takes minutes instead of hours.
