Artificial intelligence has rapidly evolved from science fiction to an integral part of our daily lives. For those who have been hesitant about adopting AI or are unsure how to incorporate it into their routines, this comprehensive guide will demystify AI technology and provide practical insights for users of all ages and technical backgrounds.
What is Perplexity AI and How It Started
The Beginning of Perplexity AI
Perplexity AI was founded in August 2022 by four accomplished engineers: Aravind Srinivas (CEO), Denis Yarats (CTO), Johnny Ho (Chief Strategy Officer), and Andy Konwinski (President). The founding team brought impressive credentials from major tech companies – Srinivas and Yarats had worked at OpenAI, Ho came from Quora, and Konwinski was a cofounder of Databricks.
The company emerged from a shared frustration with traditional search engines that provided “endless lists of links” rather than direct answers. Their vision was to create a “conversational answer engine” that could deliver precise responses with proper source citations, filling a gap between search engines and AI chatbots.
Early Development and Launch
Perplexity officially launched to the public in December 2022 as a free beta, positioning itself as the “fastest way to get answers” to any question. Unlike ChatGPT, which initially launched without source citations, Perplexity combined the strengths of both search engines and AI chatbots by providing LLM-driven responses with inline citations.
The platform gained rapid traction, attracting 2 million unique visitors by February 2023. By early 2023, the company had pivoted from their initial Twitter-focused tool called Bird SQL to focus entirely on their core search product, reaching 10 million monthly active users. This growth trajectory continued, and by 2025, Perplexity processes over 500 million queries monthly.
