Exa
Exa (formerly Metaphor) is a neural search engine designed specifically for AI applications. Unlike traditional search engines that return lists of URLs, Exa uses embeddings-based search to find semantically relevant content and returns clean, parsed text ready for LLM consumption. It powers search for AI agents, RAG pipelines, and research tools. Founded by ex-Google researchers, Exa has raised $22M+ and serves customers including Perplexity, Anthropic (Claude web search), and thousands of AI developers. Its key differentiator is the ability to find niche, high-quality content that Google often misses, and return it as clean markdown instead of raw HTML.
- ✓ Neural (semantic) search — finds conceptually relevant content, not just keyword matches
- ✓ Auto-parsed content — returns clean text/markdown, not raw HTML
- ✓ Similarity search — find pages similar to a given URL
- ✓ Date filtering — restrict results to specific time ranges
- ✓ Domain filtering — include or exclude specific domains
