Which fits your AI stack?
Exa finds semantically relevant web pages using neural search. Amygdala finds the verified humans behind the ideas and ranks them by genuine authority signals, not page relevance. Here's how they differ.

Why developers choose Amygdala over Exa
Exa's neural search finds relevant content. Amygdala identifies the actual experts behind that content: verified profiles, authority ranks, and structured data your LLM can use directly.
Exa is a US company. Sending personal data about experts through a US-based API triggers GDPR transfer obligations. Amygdala runs 100% on European infrastructure with no US data transfers.
Web search, even neural search, surfaces SEO-gamed content, AI-generated noise, and low-quality pages that score well on relevance. Amygdala surfaces genuine human experts, filtered for real authority.
