Exa
New
AI-powered search API that understands natural language queries.
Overview
Exa is a search API designed for developers building AI applications that need semantic search capabilities. It uses neural networks to understand query intent and find relevant results beyond keyword matching. Ideal for LLM-powered apps, research tools, and recommendation systems that require intelligent information retrieval.
Pros
- Returns raw HTML content for LLM processing without wrappers
- Understands natural language intent instead of keyword matching
- Lower latency than traditional search APIs for real-time applications
- Integrates directly with LLM workflows and retrieval systems
- Filters by date, domain, and content type for precision
✕ Cons
- Limited free tier with restricted API calls per month
- Requires API key and developer setup, not a consumer tool
- Smaller index than Google or Bing for some niche topics
