Lemma Oracle
Ground‑truth infrastructure for verifiable, private AI data.
Verified Data for AI
Ground your AI in cryptographically verified facts. Lemma's verified-attributes API returns only ZK-proven data to your AI — eliminating hallucinations at the source.
Privacy by Default
Your AI gets verified answers — never the raw data. Documents stay encrypted end-to-end; Lemma itself never sees plaintext.
Share Only What's Needed
Control exactly which attributes your AI can access. Prove 'age ≥ 18' without exposing the actual age, name, or address.
