How it works
ThockBoard listens to keyboard events on whatever page you’re typing on — Google Docs, GitHub, Twitter, a plain textarea — and plays a short audio clip for each keystroke. The clips are pre-loaded from bundled audio files, so there’s no network request on every key press. The Web Audio API handles playback with near-zero latency.
You pick a sound pack and set the volume from the popup. That’s it. No settings page, no account, no configuration file.
AI Mode
ThockBoard AI reads the mood of what you’re typing — right in your browser, with no data ever leaving your device. A tiny sentiment model (752KB) runs via WebGPU (with WASM fallback), classifying your text as you type and mapping it to 5 mood zones:
| Mood | Sound Packs |
|---|---|
| 🌧️ Intense | Buckling Spring, Rain, Zilent |
| ⚡ Focused | Thocky, Typewriter, Zilent |
| ⌨️ Neutral | Cherry MX Blue, Cream, Amber |
| ✨ Happy | Topre, Holy Panda, Bamboo |
| 🎶 Joyful | Water Drop, Crystal, Wind Chime |
Hysteresis prevents rapid pack switching when your sentiment hovers near a boundary. Toggle AI Mode off anytime to pick packs manually — the choice is yours.
100% on-device. No analytics, no tracking, no telemetry. The model, vocab, and WASM runtime are all bundled with the extension. Nothing is downloaded from external servers.
