INTRODUCTION
In the last few years, we have witnessed a massive shift in how we search for information online.
Traditional search engines were once the main way we found answers. They gave us lists of links, and we had to spend time reading multiple pages to piece together the knowledge we needed.
But in 2025, we are no longer limited to that method. Artificial intelligence has changed the way we access information.
It was founded in August 2022. It is at the center of this transformation. It calls itself an “AI powered Swiss Army Knife.”
Just like a Swiss Army Knife offers many tools in one package, it provides us with multiple ways to get answers.
Instead of links alone, it gives us direct, well-structured responses that are backed by real sources.
In this article, we will find out what Perplexity AI is, how it works, its features, its use cases, and also its limitations.
By the end, we will understand why it is considered one of the smartest ways to search in 2025.
