What is Perplexity AI?
Perplexity AI, Inc. is a privately held artificial intelligence company that specializes in creating AI-driven answer engines. Unlike traditional search engines that provide a list of links, Perplexity AI synthesizes information from the web and delivers concise, contextual answers with proper citations. Its platform combines large language models (LLMs) with real-time web search to give users accurate and verifiable results. (en.wikipedia.org)
Perplexity AI has several products:
- Perplexity Search: The primary AI answer engine.
- Perplexity Pro: Subscription offering advanced models and research features.
- Comet Browser & AI Assistant: Browser-integrated AI assistant tools for enhanced productivity.
This approach positions Perplexity as a hybrid between search engines and AI research assistants, enabling users to get answers, context, and sources in one interface.
The Core Idea Behind Perplexity AI
The founding team created Perplexity AI to solve a simple yet powerful problem: traditional search engines provide links, not direct answers. Users often spend time scrolling through pages, clicking multiple sources, and manually piecing together information. Perplexity AI’s vision was to reduce user confusion (perplexity) by delivering synthesized, cited responses in real time.
The name Perplexity is drawn from natural language processing terminology, measuring how well a model predicts text. The company’s goal: turn user perplexity into clarity with AI-assisted search. (britannica.com)
Founders and the Birth of the Company
Perplexity AI was founded in August 2022 by four engineers:
- Aravind Srinivas (CEO): Former AI researcher at OpenAI, DeepMind, and Google Brain.
- Denis Yarats (CTO): Specialist in machine learning and AI systems.
- Johnny Ho (CSO): Strategy and engineering experience from Quora.
- Andy Konwinski (President): Veteran in distributed systems and scalable software (co-founder of Databricks).
The team combined deep expertise in AI, language models, and engineering to create a platform that could answer questions efficiently, accurately, and transparently. (en.wikipedia.org)
Early Development and Launch
After its founding, Perplexity spent months building its first platform. On December 7, 2022, it launched its public answer engine.

The early product quickly attracted millions of visitors. By February 2023, Perplexity had over two million unique users, showing strong market interest in AI-driven, citation-based search tools. (perplexity.ai)
