Your Patient Advocate.
Always On. Always Private.
CareShield fights for you — generates prior authorizations, finds the cheapest medications, flags missed care, and answers your health questions. All on-device. Nothing ever leaves your phone.
An Advocate That Works For You
Connect your health records once. CareShield becomes your tireless advocate — fighting insurance bureaucracy, finding savings, and keeping you on track.
Shield AI — Your Private Advocate
Ask about your medications, best prices, prior authorizations, or care gaps. Shield generates PA packets, finds savings, and answers instantly — running entirely on your device. No cloud. No third parties. No exceptions.
SMART Health Card QR
Generate a cryptographically-signed QR code of your health records. Share with any provider instantly — they scan it, get your verified conditions, meds, allergies, and immunizations. No fax machines. No clipboards.
Real Hospital Prices
7.5M+ negotiated rates from 465+ hospitals. Ranked cheapest to most expensive with CMS quality stars side-by-side. Know exactly what you'll pay before you go.
Connect Your EHR
Link your patient portal via SMART on FHIR — the same secure protocol your doctor's office uses. Your conditions, meds, labs, allergies, and immunizations in one unified view.
Care Gap Alerts
Evidence-based preventive care recommendations from USPSTF and ACIP guidelines. Know when you're overdue for screenings, vaccines, or checkups — before your doctor has to remind you.
Prior Authorization + Coverage
Shield knows your payer's PA rules and generates FHIR-compliant authorization packets on demand. No more phone tag with insurance — your provider gets a ready-to-submit packet.
We Don't Track You. Period.
Most health apps upload your data to the cloud and call it "secure." We took a different approach: we don't collect it at all.
careshieldus.com does not store, track, or log user data.
No analytics. No cookies beyond what your browser needs to function. No user accounts stored on our servers. No behavioral tracking. No pixel trackers. We don't know who you are, and we want to keep it that way.
AI Runs On YOUR Device
Shield downloads a model to your browser and runs locally via WebGPU. Your health records are processed on your phone/laptop — never sent to any server, API, or cloud service. Period.
We Can't Read Your Conversations
Shield AI conversations happen entirely on your device. We never see, store, or log what you ask. Your conversation history lives in your browser only — clear it anytime.
We Never Sell Your Data
No advertisers. No data brokers. No third-party "analytics partners." Your health information is not a product. We make money by being useful, not by exploiting you.
AES-256 Encryption + TLS 1.3
OAuth tokens encrypted at rest with AES-256-GCM. All connections over TLS 1.3. Same encryption standard used by banks and the military.
CARIN Code of Conduct
Built to the CARIN Alliance Code of Conduct for Consumer-Facing Applications — the healthcare industry's gold standard for patient data handling and transparency.
No Training on Your Data
We will never use your personal health information to train AI models. The AI already knows medicine — it doesn't need to learn from your private records.
⚠️ AI can make mistakes
Shield AI is not a doctor. It may provide incorrect or incomplete information. Always verify with your healthcare provider. If Shield gives you a wrong answer, you can help us improve by voluntarily sharing the conversation.

Install It. Works Offline.
CareShield is a Progressive Web App. Add it to your home screen and it works like a native app — even without internet. Your records stay cached locally and Shield AI runs offline once the model is downloaded.
Backed By Federal Data
Every hospital price traces back to a public filing. No estimates. No black boxes. Fully auditable. Health records come directly from your provider via SMART on FHIR — the HL7 interoperability standard.
What We're Building Next
We're not stopping here. These features are actively in development.
Document Scanner
Upload or photograph an EOB, medical bill, or insurance letter. Shield reads it on-device and explains what you owe, what's covered, and what to question.
Payer Connections
Link your insurance payer directly. Combine your health center records with payer claims data to verify you're getting the preventive care your plan covers — and find in-network providers for services you need.
Electronic Prior Auth (ePA)
Shield generates FHIR-compliant prior authorization packets with clinical justification, ICD-10 codes, and payer-specific criteria. Structured for electronic submission to Aetna, UHC, and other payers via Da Vinci PAS.
Voice Input
Talk to Shield instead of typing. Ask about your meds, screenings, or coverage hands-free — on-device with the same privacy guarantees.
