Hi, I'm Samuel Mensah

I build privacy-first AI that runs entirely on-device — no cloud, no telemetry, no data leaks.

Portfolio · GIA Live Demo · LinkedIn · Email


Who I am

A developer from Ghana who believes privacy should be the default, not a feature.

Most AI products upload your data to someone else's server. The things I build run on your device — architected so data collection is impossible, not merely optional.


Flagship: GIA — Generative Interface Agent

A full AI workspace that runs entirely on-device. No backend. No account. No telemetry. A genuine agentic AI you can install and use offline.

  • 21+ AI providers — Anthropic, Google, OpenAI, Groq, Mistral, xAI and more, hot-swappable
  • 99+ tools across 24 categories — a real agentic tool loop executing client-side
  • Wake-word voice control — 100% offline, ~97% accuracy
  • On-device LLM — Transformers.js WASM, works with zero internet
  • Multi-tier memory — working, semantic, and episodic
  • MCP protocol support + plugin system + security hardening
  • Capacitor shell → installable Android app
