Vital

Built for the Alan × Mistral AI Health Hack — April 11, 2026, Paris.

Quick start

Requires Node.js 22+, pnpm 10+ (corepack enable) and an OpenRouter API key.

git clone https://github.com/vitalvie/vital.git && cd vital
pnpm install
cp apps/web/.env.example apps/web/.env   # then set OPENROUTER_API_KEY
pnpm dev

Open http://localhost:3000. Tap the watch, or pick a question. The mic works on localhost or HTTPS; otherwise, type a question. The app opens on a well-rested sample day.

Change the mocked data

Under the title, pick Short night, Well rested or Stressful week, or click Adjust numbers and move the sliders for last night's sleep, HRV and resting heart rate. Vital answers with those numbers.

To change the 14-day history or the presets, edit apps/web/src/data/mock-health.ts, then update the expected scores in the tests so pnpm test stays green.
