What is Perplexity AI and how does it work?

Are you tired of searching for answers to every question on Google? Do you want someone to give you accurate and verified information in one place, without any ads or useless links? If yes, then you must know about Perplexity AI. It is not just an AI chatbot, but a new and better way to find and research information.

We will know in detail what Perplexity AI is, how it is different from Google, and why it is so useful for you.

What is Perplexity AI?

In simple words, Perplexity AI is an AI-powered search engine that gives you direct, accurate, and reliable answers. Instead of showing a lot of links like Google, it understands your question, searches for information on the web, and then presents that information to you in a concise and organized form.

It is not a simple chatbot that just converses. Its main job is to provide “knowledge-based answers”. It mentions the sources from where it has taken the information along with its answers, so you can easily cross-check that information.

Perplexity AI, the company behind the Perplexity AI search engine, is a privately held startup co-founded by Aravind Srinivas, Denis Yarats, Johnny Ho, and Andy Konwinski in 2022

How is it different from Google?

This is the biggest question that comes to everyone’s mind. To understand Perplexity, it is easiest to compare it with Google:

Answers vs. Links:

Google shows you links to millions of web pages related to your question. You have to open those links and find the right information yourself. Perplexity gives you the answer to your question directly and also gives links to the sources below it so that you can be satisfied.

Ad-free experience:

Google search results often contain ads, which can distract you from the main information. Perplexity is completely ad-free, giving you a clean and focused experience.

Detailed and coherent answers:

When you ask Perplexity a complex question, it does in-depth research on the topic and gives a detailed and well-structured answer, as if someone had written a short article. It often also suggests “related questions” after the main answer, allowing you to understand the topic more deeply.

How does Perplexity AI work?

Perplexity AI works using several advanced technologies:

Natural Language Processing (NLP):

When you type your question, Perplexity’s NLP system understands your words and phrases, not just keywords. It understands the intent and context behind your question.

Live web search:

Perplexity doesn’t rely on a static database. It searches the web live for your question, which means it can give you the most recent and updated information. It can also give accurate answers on new news, research papers, and trending topics.

Information Synthesis:

After searching, it gathers information from multiple reliable sources. Then, it uses a large language model (like GPT-4, Claude 3, or its own model) to turn that information into a coherent and easy-to-read answer.

Citation:

This is the most important feature of Perplexity. With every answer, it gives numbered links (citations) to the web pages or articles from which it has taken the information. This makes it a reliable and transparent tool.

Some special features of Perplexity

Follow-up Questions:

After every answer, it prompts you to ask more questions, allowing you to get to the bottom of any topic.

Copilot:

This is an interactive mode where Perplexity helps you improve your answers by asking you questions.

Libraries and Collections:

You can save all your research in one place.

File and Document Upload:

You can upload PDFs, text files, or other documents and ask Perplexity questions based on them. (This feature is available in Pro subscription).

Perplexity AI is not just a search engine; it is an AI-powered research assistant. It emphasizes on “understanding” rather than “finding” like Google.
