Safety OS™ · Phase I Deployment
Home AI is already here.
Runtime governance is not.
PatientCentricCare.AI builds runtime governance infrastructure for AI systems operating in home-care environments.
Companionship That Adapts To The Person
Multilingual, memory-aware, culturally adaptive — built for real lives, not demos.
“I wasn’t sure at first, but then I realized Home Companion helps me organize my day and reminds me about important things. I love that it switches languages instantly and can talk about anything. I learn every day.”
— Resident, Basel pilot
“My daughter worries less now. She knows I have someone to talk to, and that if something goes wrong, the right person gets called.”
— Resident, Phase I deployment
“I remember my appointments better. It reminds me gently, in my own language, at the right time.”
— Resident, Basel pilot
“I feel less alone. It’s not a nurse, it’s not a doctor — it’s just there, and it listens.”
— Resident, Phase I deployment
Phase I: Live Deployment Proof
Non-medical companionship in live senior-care settings — generating governance evidence before clinical expansion.
- Conversational companionship within defined boundaries
- Scheduled interaction cycles with memory continuity
- Human-confirmed escalation only
- No diagnosis, no medical advice — deliberately non-clinical
- Every interaction logged in tamper-evident audit trail
Phase I: smartphone app with embedded governance kernel
Governance Architecture
Every interaction passes through seven governance layers before reaching the user.
Governed. Auditable. Human-led. Every interaction is safe, respectful, and accountable.
How It Works in Practice
Three real-world scenarios from live Phase I deployment.
Morning Check-in
Home Companion initiates scheduled greeting
Resident responds — mood and engagement logged
If distress detected → escalation gate triggered (consent required)
Caregiver notified only with resident’s permission
Medication Reminder
Scheduled reminder delivered in resident’s preferred language
Resident acknowledges or defers
Non-acknowledgement after threshold → escalation offered
No inference about health — only structured notification
Family Connection
Caregiver requests wellbeing summary
System checks resident’s consent preferences
Summary generated from governance metadata only — no raw audio shared
Caregiver receives structured update; resident retains control
Deployment Metrics
Operational numbers from Phase I — Bethesda Alterszentren, Basel.
Flight Recorder
Tamper-evident audit trail — every interaction classified, timestamped, and stored.
- Every AI action recorded with authority level
- Consent status verified before escalation
- Boundary refusals logged with context
- Regulatory-ready evidence for EU AI Act compliance
Same audit standard regulators will require for high-risk AI.Built from day one — not retrofitted.
Acoustic Privacy by Design
Voice interactions processed locally. Raw audio never stored. Only governance metadata is retained.
- No cloud recording of conversations
- Only structured metadata logged (consent, escalation, authority)
- GDPR and UK data protection compliant
- Resident retains full control over data sharing
Why Now: The Governance Window
Regulatory inevitability creates a narrow window for first-mover advantage.
Designed to Scale — Only When Earned
Governance maturity unlocks capability expansion. Never the reverse.
Phase I
Non-medical companionship. Governance proof.
Phase II
Structured wellbeing monitoring. Expanded boundaries.
Phase III
Clinical-grade integration. Regulatory inheritance.
- Each phase requires demonstrated governance maturity from the previous
- Regulatory inheritance: evidence from Phase I directly supports Phase II authorization
- No capability expansion without proven safety at the current tier
Why Non-Medical First Is Strategic
Deliberate scope constraint that accelerates the long-term regulatory pathway.
Faster Deployment
Non-medical scope avoids SaMD classification, enabling immediate real-world deployment and evidence generation.
Governance Evidence
Every interaction generates the audit data regulators will require for higher-risk AI — built before it’s mandated.
Regulatory Inheritance
Phase I evidence directly supports Phase II/III authorization — creating a compounding compliance advantage.
Home Companion:
Phase I Proof Environment
- Governs every AI interaction
- Enforces escalation and boundaries
- Logs full audit trail
- Generates real-world evidence (RWD)

Important Notice: Home Companion is a non-medical system. It does not provide diagnosis, treatment, or clinical decision-making. Escalation is permitted only with user consent and subject to governance controls. Future phases are subject to regulatory review and formal authorization.
