Our Review

Exa (formerly Metaphor) offers a fundamentally different search approach using neural embeddings to find semantically relevant content rather than keyword matching. For developers building AI applications that require web search, its API is among the best available. Consumer users may find the interface less polished, but the result quality for nuanced queries is impressive.
