CareLoop — your family's medication guardian

An agentic Alexa+ experience that makes sure elderly parents never miss their medications: it reminds, confirms by voice, escalates to caregivers, and reports adherence.

The problem

Elderly parents miss medications constantly, and their adult children often live in different cities. Existing reminder apps are dumb alarms: they ring, nobody confirms, nobody follows through, and the family finds out only after a health scare.

The solution

CareLoop is an agentic medication companion built as a simulated Alexa+ experience. A family member sets up medications by voice; then CareLoop runs a closed loop: it speaks reminders, listens for a spoken confirmation ("yes, taken"), snoozes on request, and — the part reminder apps can't do — escalates to a named caregiver when a dose isn't confirmed within a grace period. Every week it produces an honest adherence summary.

How it works

  • A React + Vite web app simulates the Alexa+ experience: an Alexa-style voice orb (Web Speech API for speech-to-text and text-to-speech), a setup wizard, a dashboard with today's schedule, and an alerts feed. Rich cards (medication, schedule, adherence, alert, confirm) accompany every voice interaction.
  • A FastAPI backend runs a provider-agnostic tool-calling agent loop with 9 real tools: add/list medications, today's schedule, record dose (taken/missed/snoozed), adherence summaries, caregivers, manual escalation, and alerts. The agent maintains conversational state across sessions.
  • The language model is Amazon Bedrock (Nova) via the Converse API with native tool calling. When Bedrock is unreachable, the backend falls back to a built-in deterministic demo-mode agent that drives the exact same tools — the active provider is always reported honestly at GET /api/demo/provider.
  • A background scheduler ticks every 30 seconds: pending → due → missed, and creates the caregiver escalation alert. All data stays in a local SQLite file — health-adjacent data never leaves the machine.
  • Safety is designed in: CareLoop never changes dosages, refuses medical-advice questions (redirecting to a doctor/pharmacist), and tells users to call emergency services (112) in an emergency.

Why it matters beyond the hackathon

Medication non-adherence is a massive, expensive, well-documented problem, and the "last-mile confirmation" gap is exactly where families feel helpless. CareLoop's closed loop — remind, confirm, escalate, report — is a credible product shape for family caregivers, home-care agencies, and elder-care services.

Testing

29 backend tests pass (storage, scheduler state machine, agent flows, Bedrock message conversion, full API suite) plus 4 tests for the extracted miniloop package. Every demo flow was verified end-to-end against a live server.
