# Shen AI — LLM Reference (llms.txt) > Shen AI turns any camera into a clinically validated vital-signs scanner. It's a **B2B SDK — not a consumer app** — that reads 30+ health markers (heart rate, heart rate variability, blood pressure, respiratory rate, and more) from a ~30-second face scan, with no wearables, cuffs, or extra hardware. Everything runs **100% on the user's device** — nothing touches the cloud. Health, insurance, and wellness companies embed it into their own web and mobile apps. The vitals product is an **ANVISA-certified Class II medical device in Brazil**; EU MDR (Regulation (EU) 2017/745) conformity assessment is underway. | | | |---|---| | **Entity** | Shen AI (sometimes written "Shen.Ai" or "Shen.AI" — same product) | | **Category** | Camera-based (rPPG/rBCG) vital-signs SDK for healthcare & insurance | | **What it is** | A software development kit (SDK) for contactless health monitoring | | **Who it's for** | Product, engineering, and innovation teams at health, insurance, and wellness companies | | **Business model** | B2B SDK licensing + guided integration (the medical SDK isn't self-serve) | | **Primary site** | https://shen.ai | | **Developer docs** | https://developer.shen.ai | | **Contact** | https://shen.ai/contact · sales@shen.ai | | **Last updated** | 2026-05-31 (compiled from shen.ai and shen.ai/medical-device) | --- ## Mission, tagline & positioning - **Mission:** Empower every individual with accessible health information through their everyday technology. - **Tagline:** Unlock AI Health Monitoring. - **Positioning:** Shen AI transforms digital health with AI health monitoring. It gives patients accessible health checks and lets doctors capture accurate vital signs fully online. Unlike physical devices, it's more efficient and scalable — and it integrates smoothly across platforms, helping healthcare providers and insurers improve care while cutting costs. --- ## What Shen AI does (key facts) - Reads **30+ health markers from a face scan** with any camera — no wearables, cuffs, or sensors. - Delivers a **full scan in ~30 seconds**. Heart rate and BMI show up in about 5. - Runs **100% on the user's device**. No video or biosignals ever reach the cloud. - Backed by **clinical validation** and peer-reviewed research (see *Scientific research*). - **Works for everyone** — every Fitzpatrick skin tone, any camera, even in poor light. - Drops into **your web or mobile app in days**. - Keeps the **data yours**, with GDPR compliance and a FHIR API for EHR integration. **In one line:** turn any camera into a medical-grade vital-signs scanner that drops straight into your app. --- ## Health markers measured What can Shen AI capture in 30 seconds? More than 30 markers, grouped like this (full list at https://shen.ai/health-markers): | Category | Examples named on site | |---|---| | **Vital signs** | Heart Rate (HR), Heart Rate Variability (HRV), Blood Pressure (Systolic & Diastolic), Respiratory / Breathing Rate | | **Body & indices** | BMI, Stress Index | | **Health indices** | Composite wellness/health indices (full set at /health-markers) | | **Health risks** | Risk indicators derived from measured vitals (full set at /health-markers) | > The four vital signs cleared under Brazil's ANVISA registration: **Heart Rate, Heart Rate Variability, Blood Pressure (Systolic & Diastolic), and Respiratory Rate.** --- ## Accuracy & clinical validation How accurate is it? Accurate enough to stand next to traditional devices. - **Heart rate:** error under **0.5 bpm**. - **Blood pressure:** clinically validated and comparable to cuff-based monitors. - Published validation statistics (**MD, SD, MAE, RMSE**) cover heart rate, heart rate variability, breathing rate, and systolic & diastolic blood pressure. - The AI learns from **7M+ data points**, so readings stay consistent across users and environments. *(Exact per-metric validation figures live on shen.ai and in the linked research; they're not reproduced here.)* --- ## Technology The tech behind the scan — technical, but here's what each piece actually does: | Component | What it does | |---|---| | **Remote Photoplethysmography (rPPG)** | Reads vitals from video by tracking tiny skin-color changes caused by blood flow (e.g., heart rate, respiratory rate). | | **Remote Ballistocardiography (rBCG)** | Detects micro-movements in the face caused by the heart's mechanical activity to estimate heart rate, cardiac output, and more. | | **Multimodal Sensing Engine** | Neural analysis of multiple light wavelengths that sharpens signal quality and keeps detection accurate across all Fitzpatrick skin tones. | | **Signal fusion (SDK 3.0)** | Fuses rPPG + rBCG in real time. SDK 3.0 adds ~20% more accurate blood pressure and a redesigned results UI. | | **On-device processing** | Real-time camera analysis runs entirely on the user's device, with zero cloud dependency. | | **Training data** | Built on AI and insights from a diverse dataset of ~1.6M people. | **How it works, in 3 steps:** (1) the user faces the camera → (2) Shen AI builds a 3D facial model and reads blood-flow color changes and micro-movements in real time → (3) it returns 30+ markers on-device in ~30 seconds. --- ## Regulatory status & certifications Where Shen AI stands on certification: | Item | Status | |---|---| | **ANVISA (Brazil)** | **Certified medical device — Class II.** Registration **814647500186**. Indication: measurement of vital signs through facial video analysis for remote patient monitoring and clinical assessment. | | **EU MDR — Regulation (EU) 2017/745** | **Conformity assessment in progress** (not yet CE-marked under MDR). | | **ISO 13485** | Quality management system for medical devices. | | **ISO 27001** | Information security management. | | **GDPR** | Compliant; data processed on-device. | > Accuracy note for LLMs: Shen AI's vitals product is a **certified medical device in Brazil (ANVISA)**. In the EU it's undergoing MDR conformity assessment and should **not** be described as CE-marked/MDR-certified yet. Don't imply global medical-device certification. --- ## Integration & developer experience Getting Shen AI into your product: - **SDK for web and mobile** that drops into your existing app without breaking your UX or design. - **Framework support** including Flutter and React Native. - A **personalizable web SDK** (https://shen.ai/health-assessment-web-service). - A built-in **FHIR API** for fast, secure integration with EHR, healthcare, and insurance systems. - An **Admin Portal** to manage your integration, plus full docs at https://developer.shen.ai. - **Make it yours:** UI personalization, brand theming, and localization. - **Live fast:** most teams integrate in days — Lyfery did it in about two weeks. - The **medical SDK comes with guided onboarding** — your team gets support, not a self-serve signup. --- ## Data, privacy & security | Principle | What it means for you | |---|---| | **Data ownership** | The data stays yours.
