Hack Canada 2026 · Built in 36 hours (+ 30-day build period) at Waterloo's SPUR Innovation Centre
6.5 million Canadians are family caregivers. Many live far from the elderly relatives they care for, and the constant worry about whether they took their medication, how they're feeling, or whether their cognitive health is declining is exhausting.
Existing solutions are either too clinical (and ignored), too expensive, or require the elderly person to use apps and devices they can't navigate.
What if care could just... call?
Seniora is an AI-powered elderly care platform that makes automated, natural-sounding phone calls to elderly individuals — no app downloads, no smart devices, no learning curve. Just a phone that rings.
Seniora calls your loved one at the scheduled time with a warm, conversational reminder about each medication — dosage, instructions, and all. If they don't pick up, it retries intelligently.
Daily voice-based cognitive check-ins with personalized questions (people recognition, orientation, personal memory, general knowledge). The AI evaluates answers in real-time, scores the session, and tracks trends over 30 days with beautiful analytics dashboards.
After cognitive questions, Seniora asks how the person is feeling. If the AI detects distress, it immediately alerts caregivers via Telegram and offers to connect the elder with their emergency contact — right from the call.
Every call is analyzed for vocal biomarkers that may indicate early signs of depression, Parkinson's, or changes in overall wellness. Results appear in the caregiver dashboard as radar charts and trend graphs.
Multiple caregivers can monitor the same person. Instant Telegram notifications with detailed assessment reports, emergency alerts, and call summaries keep everyone in the loop.
This project is deeply integrated with the Google ecosystem and ElevenLabs voice technology. They aren't just tools we used — they're the backbone of the entire platform.
| Product | How We Use It |
|---|---|
| Gemini API (gemini-2.5-flash) | The brain of every phone call. Generates personalized greeting scripts, evaluates cognitive assessment answers in real-time, scores emotional responses (positive/negative sentiment), produces warm answer reviews, and creates AI summaries of each session. Every single AI interaction is powered by Gemini. |
| Google Antigravity | Our primary development environment. The entire codebase — frontend, backend, API routes, database schema, call flow logic — was built inside Antigravity with its agentic AI assistance, tab autocompletion, and context-aware coding. |
| Gemini CLI | Used throughout development for rapid prototyping, debugging complex Twilio webhook flows, and generating boilerplate code for new features. |
| Firebase Auth | All user authentication — Google OAuth sign-in, email/password registration, session management, and ID token verification for API routes. |
| Google Cloud | Infrastructure foundation. Database hosting, environment management, and the deployment pipeline that keeps everything running. |
| Feature | How We Use It |
|---|---|
| Text-to-Speech | Every phone call uses ElevenLabs to generate natural, human-sounding audio. Greetings, questions, emotional responses, answer reviews — all synthesized in real-time with ElevenLabs voices so the calls feel like talking to a real person, not a robot. |
| Voice Cloning | Caregivers can clone a familiar voice (like a family member) so the elderly person hears someone they recognize on the phone. This dramatically increases engagement and trust. |
| Multi-language Support | Calls are generated in the elder's preferred language (English, Arabic, and more) with natural pronunciation and cadence. |
| Non-fatal TTS Pipeline | We built a resilient audio pipeline where every ElevenLabs call is wrapped in try/catch — if the API is rate-limited or down, the system gracefully falls back to Twilio's built-in <Say> tags so calls always go through. |
| Layer | Technology |
|---|---|
| Framework | Next.js 16 (App Router), React 19, TypeScript |
| Styling | Tailwind CSS 4, Framer Motion (page transitions, stagger animations) |
| Charts | nivo (D3-based) — RadialBar, Line, Radar, HeatMap for medical analytics |
| Database | PostgreSQL + Prisma ORM 7 |
| Auth | Firebase Auth (Google OAuth + Email/Password) |
| AI | Google Gemini API (gemini-2.5-flash) |
| Voice | ElevenLabs TTS + Voice Cloning |
| Telephony | Twilio (outbound calls, speech recognition, call recording) |
| Notifications | Telegram Bot API (caregiver alerts + assessment reports) |
| Deployment | Vultr VPS, PM2 process manager, auto-deploy via GitHub |
| Dev Tools | Google Antigravity, Gemini CLI, Claude Code, Nano Banana |
