A cross-platform AI chat desktop client (macOS first) built with Tauri + React + TypeScript + Tailwind. Lightweight, fast startup, and privacy-friendly.

• Multi-provider aggregation with unified interface
  • OpenAI, DeepSeek, Qwen (DashScope), Gemini (Google), Zhipu (GLM), Ollama (local)
• Streaming chat UI with markdown/GFM and math (KaTeX) rendering
• Session management: create, rename, delete, persist history (SQLite on Tauri, localStorage on Web)
• Safe API key storage: macOS Keychain via Tauri backend; Web falls back to localStorage
• Export conversation to Markdown (Web download or Tauri save dialog)
• Resizable two-pane layout: left settings/sessions, right conversation

• Left: settings and sessions; Right: conversation with streaming responses
• Light theme by default; Tailwind-based design system

Prerequisites:

• Node.js 18+
• Rust toolchain (for Tauri): rustup default stable

npm install
npm run dev

Run desktop app (Tauri dev):

npm run build          # Web build
npm run tauri:build    # Desktop build
\# macOS specific
npm run tauri:build:mac:arm64     # Apple Silicon
npm run tauri:build:mac:x64       # Intel
npm run tauri:build:mac:universal # Universal binary (if supported)
./scripts/build-macos.sh arm64|x64|universal
