Perplexity AI

Unlike ChatGPT, Perplexity always cites its sources, making it uniquely valuable for professionals who need verifiable information. The platform's cited answer format boosted user trust by 45% in a 2024 survey, though its revenue of $50M annually trails behind the typical unicorn by a factor of 2x. CEO Aravind Srinivas has positioned Perplexity as the 'answer engine' for the post-search-bar internet, attracting attention from Lex Fridman's podcast and major tech media while securing partnerships with leading publishers.
