Perplexity is an AI tool that works like a mix between Google Search and a chatbot. Instead of giving you a list of links, it reads the web for you and writes a direct answer, with numbered sources so you can check where the information came from.
What is Perplexity?
Perplexity is often called an “answer engine”. You ask a question in normal language, it searches the internet, reads several websites, and summarizes what it found in a few clear paragraphs. Every important claim has a small number you can click to see the original source.
Why people like it
- You can check the sources. This makes it easier to trust (and verify) the answers.
- It’s current. Because it searches the web every time, it’s good for recent news and changing information.
- No ads to scroll past in the main answers, unlike traditional search results.
- Follow-up questions work like a conversation.
What can you use it for?
- Researching a product before you buy it
- Understanding a news story in simple terms
- Comparing options: “What’s the difference between a heat pump and an air conditioner?”
- Planning a trip: “What’s the weather usually like in Lisbon in October?”
- Homework and school projects, with sources to cite
Is Perplexity free?
Yes, the free version is very usable. A paid plan gives you more advanced searches and access to more powerful AI models. Check the website for current prices.

Things to watch out for

Perplexity vs ChatGPT
Use Perplexity when you want facts with sources and up-to-date information. Use a chatbot like ChatGPT or Claude when you want help writing, brainstorming, or creating something.
