Patient-Centric AI Health Platform: Your Records, Understood

A working patient health record (PHR) mobile app with a supporting provider-platform prototype: one longitudinal health timeline, an AI assistant grounded strictly in the patient's own records, and consent-based sharing with care providers.

The Problem We Saw

Health records live scattered across hospitals, labs, pharmacies, and paper files — and it's patients who pay for the fragmentation. They carry documents between providers, retell their history at every visit, and struggle to interpret reports written in clinical language. Coordination failures like a test booked with an unavailable physician surface as the patient's problem to solve. Existing hospital systems are built for institutions, not for the person the data is actually about.

What We Built

We built a patient-centric PHR platform with the patient's mobile app at the center: a longitudinal timeline of labs, prescriptions, and diagnoses; medication and allergy tracking; report uploads with document scanning; appointment booking; provider messaging; emergency health info; and wearable data integration. An AI layer makes the records usable — multimodal LLM pipelines turn multi-page lab report PDFs and even handwritten prescriptions into structured history, and a conversational assistant answers questions in plain language using retrieval-augmented generation grounded exclusively in that patient's own verified records, isolated per user at the database level. AI is assistive by design: clearly labeled, never diagnosing, and architecturally separated from the immutable source-of-truth medical data. A supporting provider-platform prototype covers clinic and doctor workflows — appointments, prescriptions, and consent-based access to patient records — on an India-ready architecture aligned with ABDM, with consent lifecycle management, audit logging, and local data residency built in from the start.

What It Enables

  • Patients ask questions about their own records in plain language and get answers grounded only in their verified data
  • Lab reports and handwritten prescriptions become structured, searchable health history instead of static files
  • One longitudinal timeline replaces scattered records across labs, hospitals, and pharmacies
  • Providers see patient records through explicit, auditable consent — not ad-hoc document sharing
  • Safety by design: AI outputs are assistive and clearly labeled, source medical records stay immutable, and every access is audit-logged
