Exa

Exa is a search engine designed to be used by language models and developers. Instead of matching keywords, it uses embeddings to find pages that match the meaning of a query, which works well for finding research, companies or niche content. Its API returns clean page contents, supports filtering by date and domain, and offers tools for building research agents. A web interface lets anyone try the same search. Exa has a free allowance and usage-based pricing. It is popular with teams building AI products that need fresh, relevant web data.
