Welcome

Welcome to Lemma developer docs. Build AI applications with verified knowledge infrastructure that eliminates hallucinations and provides cryptographic proof of sources.

Lemma is deterministic knowledge retrieval for regulated industries. Every search returns the same results every time, with mathematical proof that citations came from FDA sources.

Why Lemma?

Deterministic

Phase-based retrieval using Hamming distance, not probabilistic cosine similarity. The same query always returns the same results in the same order.

Verifiable

128-bit binary fingerprints provide cryptographic proof. Anyone can independently verify that a citation corresponds to exact FDA source text.

Traceable

Every piece of information traces directly to official FDA sources (DailyMed). Complete provenance from query to government source.

Built for AI Applications

Lemma provides the knowledge infrastructure layer for AI companies building in regulated industries. Replace probabilistic source citations ("95% similar") with deterministic, verifiable knowledge that provides mathematical proof of every claim.
