How It Works

<2-4 sentences on core approach / design (key algorithms, models, data flow, or architectural choices) and why this approach is advantageous or novel.> This application leverages a Python 3.12+/Rust backend integrated with LangChain for LLM communication via the Anthropic API. The frontend utilizes Next.js with Electron or Tauri for native desktop and mobile builds. Its architecture prioritizes privacy through local chat storage and optional reverse proxy support, while offering optimized response streaming and multi-modal input capabilities.
