Neural (embedding-based) web search over Exa's curated index, which finds pages
Neural (embedding-based) web search over Exa's curated index, which finds pages by meaning rather than keyword overlap. Use it when a keyword engine returns the wrong thing: conceptual questions, 'pages like this one', or niche technical writing. Returns up to 10 results with title, URL, published date and author. Complements the Brave-backed web search rather than replacing it.
