The Evidence
Layer for AI
Walk one note through your workflow: clinician records, AI drafts, CDS reviews, EHR entry, sign-off. GLACIS turns each handoff into cryptographic evidence.
The Scenario
Your hybrid AI+human workflow meets hospital procurement
The 98% edit-free claim is compelling. Procurement wants evidence:
Compliance: How do you prove CDS actually reviewed each note—not just clicked approve?
Legal: If a note is disputed, can you reconstruct what the AI drafted vs. what CDS changed?
CMO: How do we verify the signed version matches what went into the EHR?
Your audit logs say "reviewed."
Procurement says "prove the human actually looked."
The Questions
Your differentiator is under pressure
Patient challenges note accuracy. Was this AI hallucination or CDS error? Without receipts, you can't prove who authored what—or when.
Competitors add CDS-like features and make the same marketing claims. Your 15 years of experience becomes hard to prove.
The opportunity: You actually do have human oversight. GLACIS lets you prove it cryptographically on every note.
The Walkthrough
Receipts on every handoff
We attach at each step of your workflow: audio capture, AI draft, CDS review, EHR entry. Each handoff generates a cryptographic receipt—proving what happened, when, and by whom.
Every note has a receipt chain. You can show exactly what the AI drafted, what the CDS changed, and when the clinician signed. No more "trust us."
Competitive Moat
Turn "human oversight" into verifiable proof
Anyone can claim CDS review. Only one company can prove it cryptographically—on every note.
COMPETITIVE ADVANTAGE
Prove human review: Every note has attested CDS touchpoints
Win disputes: Reconstruct what happened, when, by whom
Defend your moat: Competitors can't copy cryptographic proof
REGULATORY DEADLINES
Standard of care precedes law. NIST AI RMF and ISO 42001 are already the de facto duty of care.
The window: In 18 months, AI vendors without cryptographic proof will lose deals to those who have it.
The Insight
What a dispute looks like: with vs. without
Patient says the note is wrong. The question isn't "did someone review it?"—it's "can you prove it?"
Without GLACIS
Dispute investigation
"Our logs say CDS reviewed it"
Problem: You wrote the logs. They're contestable.
Procurement Asks
"Prove the human actually reviewed"
Show timestamps, diffs, signatures
Result: Deal stalls. Same questions every time.
With GLACIS
