Six ways MrHuang makes itself useful
Not always perfectly. But consistently.
Your data stays on your hardware. No cloud sync. No data mining. Just yours.
AI Personas
Mentor, Therapist, Life Coach — each with its own voice and no filter.
Knowledge Base
Persistent memory that actually remembers. Unlike you.
Voice Input
Deepgram transcription — speak, it listens. Mostly correctly.
WhatsApp Integration
Chat with MrHuang on the app you already have open anyway.
Daily Journal
Track your thoughts. MrHuang will have opinions about them.
Dashboard
Habit tracking. It notices when you stop showing up.
Security that doesn't rely on trusting us
Your data never leaves your hardware.
The only outbound call MrHuang makes is to Claude API. Everything else stays between you and your server.

Zero Trust
Cloudflare Tunnel — no open ports, no exposed IP, no VPN required.
PIN Protection
JWT tokens with timing-safe compare. Brute force is not invited.
HMAC Webhook Verification
Every WhatsApp webhook verified with HMAC-SHA256. Spoofed messages get dropped.
Path Traversal Protection
File access is sandboxed. ../../../etc/passwd goes nowhere.
Zod Schema Validation
Every API input validated at runtime. Garbage in, error out.
What's next. Allegedly.
Native apps for the platforms you actually use. Mac, iOS, Android — because the browser isn't always where you need your AI companion.
Mac
Native menu bar app. Always there when you need it.
iOS
iPhone and iPad. MrHuang in your pocket.
Android
Android native. Because choice matters.
