Exa is an innovative AI-driven search engine designed to address the limitations of traditional search tools by providing comprehensive and customizable search capabilities. Unlike conventional engines, Exa leverages neural models and embedding-based algorithms to process and retrieve complex queries, offering users greater control and personalization. The platform's infrastructure includes a sophisticated crawling system that gathers and preprocesses vast amounts of web data, transforming it into embeddings for efficient retrieval. Exa's commitment to the "Bitter Lesson" emphasizes the continuous improvement of search capabilities through increased computational power, illustrated by their use of a substantial GPU cluster. The company offers two products: Exa Search, a general API for quick results, and Exa Websets, tailored for more complex queries requiring significant computation time. With a mission to achieve "perfect search," Exa aims to revolutionize the way businesses and individuals access and utilize information on the web.
