I Built GIA: A Fully Private, On-Device AI Workspace That Runs on Your Phone (No Cloud, No Telemetry)

Hey devs,

I've always been frustrated with how much of our AI usage depends on big cloud providers — constant API costs, data leaving your device, and no real privacy. So I decided to build GIA (Generative Interface Agent) — a complete AI workspace that lives entirely on your device.

What is GIA?

GIA is a private, on-device AI workspace built with React 18 + TypeScript + Capacitor. It runs as a native Android app (and can be adapted for iOS/web) while keeping everything local except for the AI API calls you explicitly configure, I am planning on adding a function that lets GIA connect to local models

No backend.

No telemetry.

No data collection.

Your API keys stay on-device in IndexedDB.

✨ Key Features

• Agentic Loop — Autonomous reasoning with multi-turn tool use and sub-agent delegation
• Live Reasoning Panel — Watch the model think in real-time with streaming thoughts
• Deep On-Device Memory — Persistent memory with relevance scoring, pinning, auto-extraction, and knowledge management
• Voice Mode — Wake word ("Hey Gia"), push-to-talk, transcript polishing, and TTS
• Built-in Tools:
  • Web search via DuckDuckGo (with citations)
  • File read/write operations
  • Code execution (Python/JS/C++ via Piston)
  • Image generation (DALL·E 3 and others)

• Multi-Provider Support (direct API calls, no proxy):

  • Anthropic (Claude 3.5/3.7)
  • Google Gemini (Flash/Pro with vision)
  • OpenAI (GPT-4o, o1, o3 series)
  • Groq (ultra-fast inference) -Cerebral(also fast )
  • Minstral....
  • OpenRouter + 100+ models

• Skills System — Role presets (Developer, Researcher, Tutor, Creative, Security Analyst, etc.)

• Beautiful UI — Built with Tailwind, Framer Motion, Recharts, Mermaid diagrams, and KaTeX

Tech Stack

• Frontend: React 18 + TypeScript 5 + Tailwind + Framer Motion
• State: Zustand (persisted to IndexedDB)
• Mobile: Capacitor (Android WebView)
• Build: Vite

Why I Built This

As someone building multiple privacy-focused tools (Core-x Privacy Toolkit, etc.), I wanted an AI companion that aligns with my values — maximum control and zero unwanted data sharing.

GIA is the result: a powerful daily driver that feels like having a full AI OS in your pocket.Gia is still in testing phases and still has some problems though I ain't gon lie about that, being a solo decision frustrating man.. I need help, I need support, I need you to help improve GIA..
