Exa (formerly Metaphor) is an AI-powered web search and data enrichment platform that provides real-time, high-quality web data for AI applications. Its semantic search engine uses neural embeddings to understand query intent rather than matching keywords, making it particularly effective for AI agents and RAG workflows. Exa offers a comprehensive suite of APIs including Search, Websets for structured data collection, and Research endpoints for agentic workflows. The platform excels at citation export with multiple formats (BibTeX, APA, MLA) and is widely used by developers building AI-powered research tools.
