What is Perplexity AI

Perplexity AI is a search engine that uses advanced language models (AI) to understand your question and give you a direct, coherent answer, instead of a list of links. Imagine Google but with a smart assistant that reads the results for you and summarizes what matters.

It was founded in 2022 by former Google and OpenAI engineers, and has grown rapidly since. Its proposition is simple but powerful: making internet search more efficient and less frustrating.

How it differs from Google

• Google gives you a list of links and you have to find the answer yourself.
• Perplexity reads those links, extracts the information, and gives you the answer directly.
• ChatGPT can give you answers, but without sources and with potentially outdated data.
• Perplexity combines the best of both: direct answers with verifiable sources and current data.

Pro-tip: Perplexity is ideal for quick research, academic work, or when you need concrete data with sources. Don’t use it for creative tasks like writing stories; for that, ChatGPT is better.

How Perplexity AI works

The process is simple:

1. You type your question in natural language, as if you were asking a person.
2. Perplexity searches the internet in real time using its own web crawler.
3. The AI analyzes multiple sources and synthesizes a coherent answer.
4. It presents the answer with citations and links to the original sources.

What makes Perplexity special is that you can verify every piece of data. Each claim comes with a number in brackets that links to the original source. If you doubt something, you click and check the source yourself.

Search modes

• Quick Search: Fast search, like using Google but with a direct answer.
• Pro Search: Deep search that analyzes more sources and gives more complete answers. Costs more “tokens” (you have a daily free limit).
• Focus: You can filter by source type (academic, videos, Reddit, etc.).

What is Perplexity AI for

These are the use cases where Perplexity really shines:

Research and academic work

If you’re doing research, Perplexity gives you answers with cited sources. It’s like having a research assistant that does the preliminary work. You can ask about studies, statistics, or specific data and it’ll give you the sources.

Current data

Unlike ChatGPT, which has a knowledge cutoff, Perplexity searches the internet in real time. If you ask about the current price of something, today’s news, or tomorrow’s weather, it gives you current data.

Quick comparisons

You need to compare two products, services, or technologies. Instead of opening ten tabs, ask Perplexity and it’ll give you a comparison with concrete data.

Purchase decisions

“What’s the best laptop for students under 600 euros?” Perplexity will search reviews, compare specs, and give you a well-founded answer.

Learning new concepts

If you want to understand a topic you don’t know, Perplexity gives you a clear explanation with the option to dig deeper into the sources.

Perplexity AI free vs paid

For casual use, the free version is very complete. If you research professionally or need unlimited deep searches, the Pro plan is worth it.

How to use Perplexity: practical tips

From your phone

1. Download the Perplexity app from the Play Store or App Store.
2. Create a free account.
3. Start typing or dictating your questions.

Tips for better results

• Be specific: “What are the side effects of ibuprofen in people over 65?” is better than “ibuprofen side effects.”
• Use Pro mode for complex topics that need deep analysis.
• Ask for sources: “Give me the 3 best laptops for programming with sources” gives you verifiable answers.
• Use Collections: Perplexity lets you organize your searches into themed collections. Great for projects.

Pro-tip: If you combine Perplexity for research and ChatGPT for writing, you have a very powerful AI work team. Research in Perplexity, write in ChatGPT.
