Emome — BlackBox Mode (Offline-First)

Tagline: “A relationship flight recorder that runs fully offline.”

This is a free, offline-first add-on prototype for Emome:

• Record a quick debrief (speech if your browser supports it; otherwise type)
• Generate:
  • Interaction Event JSON
  • Reasoned explanation
  • Relationship Pulse update
  • Next-time micro-script
• Stores everything locally in IndexedDB
• Includes a PWA service worker so the UI loads offline after first visit

Important honesty note: true offline speech-to-text depends on your device/browser.
This prototype uses the browser SpeechRecognition API if available.
The core analysis + storage works fully offline.

Run locally

npm install
npm run dev

Open:

• http://localhost:3000/blackbox

Build

npm run build
npm run start

Deploy (Vercel)

• Push to GitHub
• Import in Vercel
• Done

Offline behavior

• First online visit caches the app shell via public/sw.js
• Your BlackBox logs are stored locally (IndexedDB)
• In airplane mode:
  • the UI loads
  • you can type debriefs
  • analysis + pulse updates work
  • speech recognition may or may not work depending on device

How the Pulse works

• Each interaction produces an eventScore in [-1, +1] based on:
  • valence (draining vs nourishing words)
  • intensity (0..10)
  • duration (log-weighted)
• Pulse is a smoothed 0..100 signal (stable but responsive)

Next upgrades (if you want to go “judge-melting”)

1. Add true offline STT (WASM Vosk/Whisper) + cache the model files for airplane-mode transcription.
2. Add Live Boundary Guardian (opt-in) using on-device audio processing.
3. Add optional local encryption (WebCrypto) with a user passphrase.
