Perplexity AI is a venture-backed conversational search engine founded in 2022 that provides real-time, cited answers by combining large language models with web retrieval. Led by CEO Aravind Srinivas and backed by notable investors including Jeff Bezos, NEA, and NVIDIA, the company positions itself as an 'answer engine' alternative to traditional search through source citations and transparent methodology. Despite rapid growth and significant funding, the company faces ongoing legal challenges regarding content scraping practices, publisher relationship tensions, and questions about long-term competitive viability against established tech giants in the intensifying AI search market.
