Perplexity AI
specialtyUS · Founded 2022
Search-first answer engine. Citations on every claim.
Perplexity AI built a product on top of frontier models rather than building the models itself. The answer engine format — synthesis with inline citations — proved to be a compelling alternative to traditional search for research tasks. The model-agnostic approach means the quality tracks whoever is best at a given time.
