🌐 What is Perplexity AI?

Perplexity AI is a powerful AI-based search engine and conversational assistant that combines advanced natural language processing (NLP) with real-time web access. It’s designed to provide factual, concise, and citation-backed answers to user queries—essentially blending the functions of a search engine and a chatbot.

Unlike traditional search engines, which return a list of links, Perplexity AI often provides direct answers to questions with cited sources, making it more transparent and user-friendly.

🏗️ Foundation & Background

• Founded: 2022
• Founders: Aravind Srinivas (former OpenAI researcher), Denis Yarats, Johnny Ho, and Andy Konwinski
• Headquarters: San Francisco, California
• Backed by: Prominent venture capital firms including IVP and NEA, and notable individuals such as Jeff Bezos and NVIDIA’s NVentures.

The company was born out of the vision to create an AI that not only generates text but reasons with it, offering trustworthy, real-time knowledge retrieval.

🤖 Core Features

1. Conversational Search

Users interact with Perplexity in a chat-based format, similar to ChatGPT or Google’s Gemini. You can ask questions in natural language, and it responds with coherent, often multi-paragraph answers that cite multiple sources.

2. Live Web Access

Perplexity AI has built-in access to the internet, allowing it to:

• Fetch the latest information
• Provide answers based on real-time content
