In radio, “five by five” means your signal is coming through perfectly: loud and clear. Your medical record deserves the same. Right now, AI scribes are writing millions of notes with no independent check, and one wrong note is a huge liability and a professional reputation crisis waiting to happen. Five x Five is not another scribe. It works beside yours: it seals what was said in the room, then verifies the chart against that sealed record live, flagging every discrepancy for the clinician to review. The black box for the exam room. So when a record is ever questioned, you never rely on memory or word against word. Trust is a feeling. Proof is a fact.
A clinician reaches for an AI scribe because the documentation burden is crushing, and it helps. The quiet assumption underneath is that they will read every line it writes. But between a full panel, constant interruptions, and burnout, that careful read is the first thing the day takes away. The note enters the chart, and no one is told it can be checked. This is not a lapse in care. It is a gap in the system, and it is the gap Five x Five closes.
We do not replace your scribe, and we never need its transcript. Five x Five captures its own record at the moment of care and seals it. Any scribe's note is then held up to that sealed truth.
As care happens, the encounter becomes a structured, time-stamped record. One tap seals it with a cryptographic hash computed from its exact contents.
The scribe's note is checked against the sealed source. Every line gets one of three verdicts. No fourth answer, and nothing to take on faith.
Caught before sign-off. The note records that the patient denies self-harm. The sealed source shows they reported it. That single reversal is the error that follow-up care is built on, and it never reaches the chart unflagged.
The clinician, the institution, and the patient are protected by the same record, sealed once. Tap to see both sides of it.
The independent check runs as care happens, so no one has to review every line. If a note is ever questioned, you hold a sealed record that already flagged it. A complete, audit-ready trail, and early signal before a problem becomes a settlement.
You hold a verifiable copy and can confirm it yourself, without taking the vendor's word for it. A parent can hold a verified copy of a child's record, the exact thing the new provincial law is being written to protect.
Here is the record and its seal. An authorized holder can recompute the hash and confirm nothing was altered. Change one character and watch the seal break. This runs live, right now, in your browser.
In every pro sport, a disputed call goes to the booth. There is a camera, there is a tape, and the replay settles it. In medicine right now, the call gets made with no camera, and then the tape gets deleted. The problem is not that AI scribes make errors. Every source below proves they do. The problem is that no one can prove what the record got wrong, because the source is already gone. We do not sell accuracy. We sell proof.
It does not. An ambient scribe transcribes and summarizes. There is no step that compares the note back to what was said, or to the chart. That is not our opinion, it is why every regulator puts the burden on the human. Ontario’s Auditor General’s only fix was to force a clinician to attest by hand that they reviewed the note. NHS England guidance calls the clinician the “liability sink” for the AI’s output. Australia’s safety regulator found the same audio can produce different summaries. A system that cannot reproduce its own output is not checking anything. Verification is a separate job. It is the one Five x Five does.
Read the Auditor General’s report ↗It is already reaching charts uncaught. Ontario’s Auditor General found 12 of 20 approved systems recorded a different drug than the doctor prescribed. In California, a class action alleges the ambient AI (Abridge) wrote consent statements into more than 100,000 patient charts, saying patients had agreed to be recorded when they had not. Doctors Manitoba documented a scribe adding a symptom the patient had denied. And when JAMA had roughly 23,000 patients read their own notes, 1 in 5 found an error and 42% called it serious, caught only because the patient happened to read it. The safety net today is that someone notices. That is luck, not a system. We replace it with proof.

The training. A therapist, crisis manager, and mother of four, she trained at the Waterford Hospital through the Department of Ethics, with work in inpatient psychiatry and Employee Assistance. She learned to chart accurately and to notice the gaps, where what was said and what was written diverge.
The build. She founded GNOSIS to close that gap: a sealed, independently verifiable record of what was known, decided, and done, that holds up without anyone having to take it on trust. Trust, when it matters most, is not a feeling. It is a file. Five x Five is that record for healthcare.

The moment a decision is made, the proof of how it was made starts to disappear.
Flip ↻GNOSIS seals consequential moments with real cryptography, SHA-256 hash chains and HMAC-SHA256 signatures, so what was said, decided, and delivered can be verified by anyone, later, without trusting whoever holds the database. Five x Five is the health record application of that engine. CIVIC applies it to community emergency management in Newfoundland and Labrador.
Canada just bet $2 billion on AI. Adoption is funded. Verification is not.
Flip ↻On June 4, 2026, Prime Minister Mark Carney launched AI for All, Canada's national AI strategy: roughly $2 billion in new investment, a 60 per cent adoption target by 2034, and a $200 million health-focused AI mission, announced from the floor of a Toronto hospital. The strategy promises AI “adopted responsibly, in a way that truly serves all Canadians.” When AI writes into the records that decide care, benefits, and liability, that promise needs a layer that can prove what happened. That layer is what GNOSIS builds.
Someone will write the rules for verified AI records. We intend to hold the pen.
Flip ↻Canada is standing up the machinery for responsible AI, from the Canadian AI Safety Institute to the Standards Council of Canada's AI and Data Governance Standardization Collaborative. GNOSIS is building to that bar and working with the Standards Council of Canada's standardization ecosystem to get the verification standard right: independent, sealed, human-signed, and checkable on anyone's equipment.

All data and processing stay in Canada. Production runs in AWS Canada (Central), the Montreal region (ca-central-1). No data leaves the country.
Encrypted in transit with TLS and at rest with AWS KMS-managed keys. HSTS is enforced in production.
Dual-factor sign-in: a password (bcrypt) plus a time-based one-time code from an authenticator app. Role-based access control (nurse, physician, clinic manager, administrator), with every write checked on the server. The sign-in surface is rate-limited, and every attempt is written to the audit ledger.
Every significant action is sealed in an append-only, hash-chained, signed ledger (SHA-256 hash chains, HMAC-SHA256 signatures). Each entry links to the one before it. Altering, inserting, or deleting any entry breaks the chain, and anyone can verify it on their own equipment, without trusting GNOSIS or the organization.
Signing keys and tokens come from a managed secrets vault (AWS Secrets Manager, KMS-encrypted), never from code or logs. Strict security headers and Content-Security-Policy. Production refuses to start if a required secret is missing.
By design we do not collect Social Insurance Numbers, government ID numbers, or insurance numbers. We work on the record only: we do not listen to conversations, record audio, or transcribe anything, and we use no third-party tracking or advertising.
We operate in line with Canadian privacy law, including PIPEDA and Newfoundland and Labrador’s Personal Health Information Act (PHIA).
An independent third-party penetration test, a Privacy Impact Assessment, and a data-sharing agreement with the health authority are completed before any real personal health information is processed. This page describes intended production controls and is not a substitute for the health authority’s own security assessment.

We are building toward the Web Content Accessibility Guidelines (WCAG) 2.1 Level AA, and we treat accessibility as part of the product, not an afterthought: keyboard navigation, sufficient colour contrast, text alternatives for meaningful images, and support for screen readers.
Accessibility is continuous. As the product moves from evaluation into pilot, we test with assistive technology and address issues as they are found.
If you encounter a barrier, or need information in an alternative format, contact info@gnosisethical.com and we will work with you.
