Perplexity is a free AI search tool that answers your questions in plain language and shows you exactly where each answer came from. Instead of scrolling through a page of links like a normal search engine, or getting an answer from a chatbot with no sources at all, Perplexity gives you a short, clear answer with numbered links you can click to verify it yourself.
Think of it as a research assistant that always shows its work.
Quick summary
- Perplexity answers questions in plain language and links each part of the answer to its source.
- It is free to try, with no account required to get started.
- It is useful for research, fact-checking, and comparing options without ten open tabs.
- You can ask follow-up questions in the same thread — it remembers the context.
Who it is for
Perplexity is especially useful for:
- Anyone who wants a quick, trustworthy answer without digging through ten different websites.
- People doing research for school, work, or a personal project who need to double-check where information came from.
- Beginners who have been burned by an AI chatbot confidently making something up, and want a bit more accountability in their answers.
- Anyone comparing products, prices, or options who wants an organized summary instead of ten open tabs.
You do not need any technical skill to use it — if you can type a question into a search bar, you can use Perplexity.
How to use it
- Go to Perplexity's website or app. It is free to try, and no account is required to get started, though a free account unlocks more features.
- Type your question in plain language, just like you would ask a person — for example, "What's the difference between a Roth IRA and a regular IRA, explained simply?"
- Read the short answer it gives you, then check the small numbered links next to each part of the answer — these show you exactly which source that piece of information came from.
- Click through to any source you want to double-check or read in more detail.
- Ask a follow-up question in the same thread if you want it to go deeper or explain something more simply — it remembers the context of your conversation.
Next time you would normally type a question into a search engine and end up with ten tabs open, try asking Perplexity instead, and see how much faster you get to a clear, sourced answer.
