So I decided to build <strong>GIA</strong> (Generative Interface Agent) — a complete AI workspace that lives entirely on your device.</p> <h2> What is GIA? </h2> <p><strong>GIA</strong> is a private, on-device AI workspace built with <strong>React 18 + TypeScript + Capacitor</strong>. It runs as a native Android app (and can be adapted for iOS/web) while keeping everything local except for the AI API calls <em>you</em> explicitly configure, I am planning on adding a function that lets GIA connect to local models </p> <p>No backend.<br><br> No telemetry.<br><br> No data collection.<br><br> Your API keys stay on-device in IndexedDB.</p> <h2> ✨ Key Features </h2> <ul> <li> <strong>Agentic Loop</strong> — Autonomous reasoning with multi-turn tool use and sub-agent delegation</li> <li> <strong>Live Reasoning Panel</strong> — Watch the model think in real-time with streaming thoughts</li> <li> <strong>Deep On-Device Memory</strong> — Persistent memory with relevance scoring, pinning, auto-extraction, and knowledge management</li> <li> <strong>Voice Mode</strong> — Wake word ("Hey Gia"), push-to-talk, transcript polishing, and TTS</li> <li> <strong>Built-in Tools</strong>: <ul> <li>Web search via DuckDuckGo (with citations)</li> <li>File read/write operations</li> <li>Code execution (Python/JS/C++ via Piston)</li> <li>Image generation (DALL·E 3 and others)</li> </ul> </li> <li> <p><strong>Multi-Provider Support</strong> (direct API calls, no proxy):</p> <ul> <li>Anthropic (Claude 3.5/3.7)</li> <li>Google Gemini (Flash/Pro with vision)</li> <li>OpenAI (GPT-4o, o1, o3 series)</li> <li>Groq (ultra-fast inference) -Cerebral(also fast )</li> <li>Minstral.... </li> <li>OpenRouter + 100+ models</li> </ul> </li> <li><p><strong>Skills System</strong> — Role presets (Developer, Researcher, Tutor, Creative, Security Analyst, etc.)</p></li> <li><p><strong>Beautiful UI</strong> — Built with Tailwind, Framer Motion, Recharts, Mermaid diagrams, and KaTeX</p></li> </ul> <h2> Tech Stack </h2> <ul> <li> <strong>Frontend</strong>: React 18 + TypeScript 5 + Tailwind + Framer Motion</li> <li> <strong>State</strong>: Zustand (persisted to IndexedDB)</li> <li> <strong>Mobile</strong>: Capacitor (Android WebView)</li> <li> <strong>Build</strong>: Vite</li> </ul> <h2> Why I Built This </h2> <p>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.</p> <p>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..</p> <h2> Try It Yourself </h2> <p><strong>GitHub</strong>: <a href="https://github.com/alpha-1-design/gia-app" rel="noopener noreferrer">https://github.com/alpha-1-design/gia-app</a></p> <p><strong>Setup</strong>:</p> <div class="highlight js-code-highlight"> <pre class="highlight plaintext"><code> bash git clone https://github.com/alpha-1-design/gia-app.git cd gia-app npm install npm run dev # For Android: npm run build npx cap sync android </code></pre> </div> ai opensource agents beginners
