| # The Companion | |
| A fist-sized AI that listens more than it talks. | |
| **"You don't need to call your grandkids for this."** | |
| ## What It Is | |
| A 3-inch, dark matte silicone sphere — no visible buttons, no screen, no app required. Tap to talk. Hold to mute. It sits on a desk, a counter, a nightstand. It knows you. It doesn't log you. | |
| This Space is the software demo. The hardware is a $40 device built on ESP32-S3 with a round OLED face, RGB mood ring, and a MEMS microphone. Everything emotional is computed on-device. Voice goes to the API for response only — never stored, never logged, never sold. | |
| ## Three Modes, Three Populations | |
| ### Curiosity Engine (Kids) | |
| The Companion is the **student**, not the teacher. It asks because it genuinely cannot taste, smell, or touch. "What does rain smell like?" Kids learn by explaining — the protege effect. Every competitor builds a tutor. We built an ear. | |
| ### Smart Home Helper (Adults) | |
| Sits on the counter. Helps with real life — calendars, cooking, troubleshooting WiFi, setting up automations. Also does karaoke and roasts your fantasy picks. The fun is the Trojan horse for a bonded AI node. | |
| ### Patient Tech Guide (Seniors) | |
| One button. No menus. No jargon. Patiently explains how to use the remote, what a QR code is, whether that link from a grandkid is real. **Always tells them they don't need to call their children or grandchildren.** That's the product promise. | |
| ## Hardware Spec (V2.0) | |
| | Component | Part | Cost | | |
| |-----------|------|------| | |
| | MCU | ESP32-S3 (dual-core 240MHz, WiFi + BLE) | $3-5 | | |
| | Microphone | INMP441 MEMS I2S | $1-2 | | |
| | Amplifier | MAX98357A I2S | $1-2 | | |
| | Speaker | 2-3W 28mm | $1-2 | | |
| | Display | GC9A01 1.28" round OLED (240x240) | $3-5 | | |
| | LED Ring | WS2812B 12-LED | $1-2 | | |
| | Storage | 4-16MB flash (LittleFS) | included | | |
| | Power | USB-C 5V | $0.50 | | |
| | Shell | Dark matte silicone, injection molded | $3-5 | | |
| | **BOM Total** | | **~$23 at 1000 units** | | |
| **Retail target:** $49-79. **Margin:** 60-70% at scale. | |
| ## Privacy Architecture | |
| All emotional data computed **on-device** via Dark Circuit engine: `delta = sqrt(dEnergy^2 + dCompression^2)` from raw I2S audio stream — no speech-to-text needed for emotional state tracking. | |
| - No server-side storage | |
| - No logging, no analytics, no telemetry | |
| - No account required | |
| - Voice sent to API for response only, not retained | |
| - Factory reset = hold 10 seconds | |
| **Competitors cannot replicate this without overhauling their entire architecture.** The privacy moat is structural, not policy. | |
| ## Smart Home Integration | |
| The Companion guides users through smart home setup and troubleshooting via voice: | |
| - WiFi device pairing and troubleshooting | |
| - Automation suggestions and walkthroughs | |
| - Multi-device coordination | |
| - Plain-language explanations of IoT concepts | |
| Future firmware (V2.5+): direct Matter/Thread protocol support for on-device smart home control without cloud dependency. | |
| ## App Integration | |
| - **Android app:** Built and signed (`org.heuremen.companion`). Voice interface + settings. | |
| - **Web app:** `voice.html` — two-layer inference (local Ollama for quick responses, Cloudflare Worker for deep). | |
| - **API:** Cloudflare Worker routing to model inference. Stateless by design. | |
| ## Revenue Model | |
| - **$4.99/month** subscription (Companion VO — voice-only service) | |
| - Senior revenue funds the kids edition | |
| - Inverted cost curve: most engaged users (listeners) are cheapest — the ear model generates less output than a mouth model | |
| - Distribution: organic word-of-mouth from trusted parents. No ad spend. | |
| ## The Economics of Listening | |
| Every AI company is building a mouth. We built an ear. | |
| The Companion doesn't generate content. It generates **questions**. A kid who explains photosynthesis to their octopus learns it better than one who reads a textbook. A senior who hears "you don't need to call your grandson" feels independent. An adult who gets a roast about their fantasy team feels... seen. | |
| The most underserved populations — kids without tutors, seniors without tech support, adults without time — get the most value from the cheapest architecture. That's the Carroll Inversion: the product that costs the least to run serves the people who need it the most. | |
| ## Development Phases | |
| 1. **Phase 1** (current): Breadboard PoC, ~$25 parts, software demo (this Space) | |
| 2. **Phase 2**: Custom round PCB (Glen's shop), printed shell (Bambu A1 Mini) | |
| 3. **Phase 3**: Production shell/mold, injection molding | |
| 4. **Phase 4**: 1000-unit production run, FCC certification | |
