AI runs on
proofs, not data.
Through Lemma's proprietary cryptography, AI and agents receive only verified facts. Decisions you can prove — without ever holding the data.
Strengthen your AI workflow
across 4 phases.
Move inputs into AI with provenance attached.
Poisoned data never arrives in the first place.
See in Solutions →Verify AI's inputs and outputs without exposing them.
Prompt tampering and its detection, in the same layer.
See in Solutions →Clear regulatory compliance without revealing the original.
AI-generated IDs and other forgeries are blocked at the same time.
See in Solutions →Put autonomous agents to work in production.
Out-of-scope actions are stopped before execution.
See in Solutions →Proprietary cryptography, three values.
Without revealing the contents,
prove it is genuine.
Only the facts they need —
chosen, and handed over.
The record that remains
can be rewritten by no one.
Lemma rides on the work you already do.
Share quality and inspection records without exposing the contents.
Check suppliers' certificates and credit without holding the originals.
Fix the basis of AI decisions. Fits domestic-law needs like active cyber defense.
Run benefits, counters, and collection without seeing personal data.
By industry, by theme, by AI adoption too. Read in from every operational scene and the risks within it.
One foundation,
three doors in.
Send proofs, not keys.
