Exa
🧠 AI AssistantsAI-first search engine built around meaning, not keywords. Neural search for research and RAG pipelines.
Our Take
Exa is the search API built specifically for AI applications. Instead of keyword matching like Google, it uses neural/semantic search to find content by meaning. Feed it a description of what you want, and it returns relevant pages, papers, companies, or people — not ten SEO-optimised blog posts saying the same thing. It's built for RAG pipelines, AI agents, and developers who need high-quality search results programmatically.
What we like
- Neural search finds content by meaning, not keywords — dramatically better results for nuanced queries
- Purpose-built for AI pipelines: clean API, structured output, easy integration with RAG systems
- Excellent for finding companies, research papers, people, and niche content Google buries
- Content extraction returns clean text, not HTML soup — saves parsing overhead
Where it falls short
- Developer-only tool — no consumer interface, you need to code against the API
- Coverage is narrower than Google — some niche or recent content may be missing
- Pricing is usage-based and can add up for high-volume applications
Verdict
Exa is essential infrastructure for anyone building AI products that need search. The semantic approach finds things Google can't, and the API is clean enough to integrate in an afternoon. For building AI agents, chatbots, or research tools, it's the search backend you want. For personal web searching, stick with Perplexity.
