Metaphor (Exa)

Exa (formerly Metaphor) is a semantic search API designed for developers building AI applications. Unlike traditional search APIs that rely on keyword matching, Exa uses neural networks to understand the meaning and context of queries, returning semantically relevant results. This makes it ideal for AI agents and applications that need to find specific types of content, discover similar articles, or retrieve information based on conceptual similarity rather than exact keywords. Exa is particularly powerful for building RAG (Retrieval-Augmented Generation) systems, research tools, and AI agents that need to search the web intelligently. The platform filters for high-quality content and provides clean, structured data for easy integration.
