Silver

AI care
for oncology.

Voice-first AI care for oncology. Silver listens, reads the body through wearables, stays in sync with the treatment calendar, and answers quiet questions, always under the oversight of a real clinician. A companion for the patient. A signal for the care team.

The gap

The hardest part of treatment
happens at home.

A patient finishes an infusion and goes home. Nausea peaks on day three. Fatigue settles by day five. Neuropathy builds quietly across cycles. The next appointment is two or three weeks away. In that time, symptoms appear, change, sometimes become serious. Some get mentioned at the next visit, retrospectively and from memory. Many are forgotten, minimised, or never reported at all.

50–70%
of treatment toxicities are under-reported or reported too late to act on
14–21d
between visits, depending on the regimen. Two to three weeks of clinical silence.

We know that systematic patient-reported outcome collection improves symptom detection, reduces emergency admissions, and extends survival. The evidence is clear. Electronic PRO platforms with structured questionnaires (PRO-CTCAE, ESAS, ePRO systems) have proven this. But adherence drops over time. The forms feel clinical, repetitive, disconnected from the patient’s actual day. Completion rates fall as treatment fatigue rises, precisely when the data matters most. Paper diaries go unfilled. Telephone triage is overwhelmed. The result is a persistent gap between what the patient experiences and what the care team knows.

Solution

Silver lives in
that gap.

Three senses, a calendar, and a clinician. Silver accompanies the patient every day, notices what the care team can’t, and hands over the moment a specialist is needed.

01

Voice

Daily check-ins by voice. Ninety seconds, no forms, no scales. The companion speaks the patient's language, listens, and extracts the clinical signal silently.

02

Body

Unified wearable data from Apple, Google, and Whoop. Sleep, heart rate, activity, and more — surfaced as a single recovery score.

03

Words

Text Q&A for the quiet questions about treatment, symptoms and side effects. Grounded in the patient’s actual data, not a generic chatbot.

+1

A clinician

A specialist always on the other side of the screen. The AI handles the everyday; the clinician steps in on red flags, on uncertainty, and whenever the patient asks for it.

Identity

A visual language
for being ill in.

Every mark, colour and line was chosen to lower the cost of being here. No clinical blue. No sharp edges. No loud anything. The identity is the therapy.

Silver draws on principles from architecture and perception research: spaces that adapt to who arrives (Alexander), interfaces the body understands before the mind parses (Norman), colour as relationship not decoration (Albers), the effort of existing as a clinical variable (Sternberg), and silence as a generous act (Zumthor).

The orb

A presence, not a button.

The hero element.

The orb breathes at a normal resting respiratory rate. It is always on screen, never hidden behind a menu. A presence, not a button.

The surfaces

Four ways in,
one companion.

The orb is the hero. Everything else is a room off the main hall, entered only when the patient has the bandwidth to enter it. Each surface is a room off the main hall, entered only when the patient has the bandwidth.

Clinician oversight

The moment a
clinician steps in.

Silver does most of the everyday work alone: the gentle check-ins, the symptom tracking, the questions about treatment. But the AI knows where its edges are. A five-level escalation system runs on every encounter. Every agent output passes through safety checks before reaching the patient. When something crosses a line, Silver acts with full context via a structured clinical handoff to the care team.

IMMEDIATE · 0 min · red flags / CTCAE G4–5

Patient directed to hospital.

When the system detects a potentially life-threatening adverse event — based on predefined clinical criteria reviewed by the supervising oncologist — it instructs the patient to seek emergency care immediately, in their own language, and simultaneously alerts the care team with full clinical context.

  • Immediate, unambiguous instruction to the patient
  • Structured clinical handoff to the oncology service
  • Companion stays with the patient through the transition
  • Encounter tagged as IMMEDIATE · hospital-directed in the audit trail

Triage thresholds follow published oncology emergency guidelines. The specific criteria for each condition are defined in the clinical protocol and reviewed by the supervising oncologist.

URGENT · 1h · CTCAE G3

Clinician notified within the hour.

Grade 3 symptoms that don’t demand the ER but do demand attention. Silver pushes a structured notification with the symptom, the trend, the wearable context, the cycle day, and the AI’s recommended next step. The clinician decides.

Data governance

Built for regulated health data.

Silver processes sensitive health data in compliance with applicable privacy frameworks — GDPR in Europe, HIPAA in the US, LGPD in Brazil, and equivalent regulations worldwide. Voice recordings, wearable signals and clinical symptoms are stored encrypted, with explicit patient consent, and retained only for the duration of the care relationship. Patients can request access, correction or deletion at any time. Data residency is configurable per deployment.

Consent

Explicit informed consent before any data collection. Patients can withdraw at any time without affecting their care.

Storage

Data residency follows local regulation. Encryption at rest, transmitted over TLS. Retention limited to the active care period plus the legally required archive.

Access rights

Patients can view, export, correct or delete their data. Clinicians access only their own patients. Audit trail on every access.

Silver

AI Care,
under clinician oversight.

Not a chatbot. Not a surveillance system. AI care that listens, watches over, stays in sync with the calendar, and knows when to call the specialist.
