About Exa.ai
Exa (formerly Metaphor) is a search engine built specifically for LLMs, using embeddings to find high-quality web content that traditional keyword search misses.
Exa.ai is a modern AI-powered search engine built specifically for AI applications, agents, and large language models (LLMs). Unlike traditional search engines that focus on ads and clicks, Exa is designed to deliver high-quality, structured, and relevant data directly usable by AI systems.
It uses neural search and embeddings to understand the meaning behind queries instead of just matching keywords. This allows it to return more accurate and context-aware results, even for complex or long-form queries.
