In the rapidly evolving world of artificial intelligence, Perplexity AI has emerged as a standout tool, often described as an “AI-powered answer engine” rather than just another chatbot. Launched in 2022 by founders including Aravind Srinivas (former OpenAI researcher), Perplexity combines real-time web search with advanced language models to deliver accurate, cited responses to user queries. As of late 2025, it boasts millions of users, partnerships with major brands like Samsung and Motorola, and innovative features that set it apart from traditional search engines and competitors like ChatGPT. This article explores what Perplexity AI is, its key features, pricing, pros and cons, and why it’s gaining traction.

What is Perplexity AI?

Perplexity AI is a conversational search engine that provides direct, concise answers backed by real-time web sources and citations. Unlike Google, which returns lists of links, or ChatGPT, which relies on pre-trained data (with potential knowledge cutoffs), Perplexity actively searches the internet, synthesizes information, and presents it in an easy-to-read format with verifiable references.

It supports natural language queries, follow-up questions, and multimodal inputs like file uploads. Available on web (perplexity.ai), mobile apps (iOS and Android), and integrations like browsers and TVs, Perplexity processes billions of queries annually, making it a go-to for research, fact-checking, and quick information retrieval.

Recent 2025 updates include:

• Perplexity Patents: An AI agent for patent research.
• Sora 2 Pro integration for advanced video generation.
• Expanded features like live flight status, sports tracking, and politician finance monitoring.
• Partnerships, such as with Cristiano Ronaldo for a dedicated hub and Samsung for TV apps.
