# Yiliu - AI Note-Taking Knowledge Base Capture anytime, auto-organize, surface on demand. ## ✨ What's New (v1.2.0) - **LibSQL Storage**: Replaced sql.js with LibSQL for better performance - **Semantic Search**: Vector similarity search with hybrid ranking - **AI Enhancement**: Auto-generated summaries and tags - **Local Embeddings**: Support for HuggingFace Transformers (no API key needed) - **Version Management**: Auto-save + manual marking for important versions ## Features | Feature | Description | Command | |---------|-------------|---------| | Record | Quick capture with AI enhancement | `/记` or type directly | | Semantic Search | Find content by intent | `/搜 <keyword>` | | List | View recent notes | `/列表` | | Edit | Modify existing notes | `/编辑 <id> <content>` | | History | View version history | `/历史 <id>` | | Export | Export to Markdown | `/导出` | | Stats | View statistics | `/统计` | ## Quick Start ### Install ```bash git clone https://github.com/DamingDong/yiliu.git cd yiliu npm install npm run build ``` ### Configure AI (Optional) ```bash export OPENAI_API_KEY="your-api-key" # Optional: Custom API endpoint export OPENAI_BASE_URL="https://api.openai.com/v1" ``` **Without API Key**: Falls back to local embeddings via `@huggingface/transformers`. Core features still work. ### Usage ``` # Record a note (AI auto-summarizes + tags) /记 Today I learned about CRDT sync with Last-Write-Wins strategy # Semantic search (understands intent) 搜 distributed sync methods # List notes /列表 # View stats /统计 # Export backup /导出 ``` ## AI Features | Feature | Model | Description | |---------|-------|-------------| | Embeddings | text-embedding-3-small / all-MiniLM-L6-v2 | Semantic search | | Summaries | gpt-4o-mini | Auto summaries | | Tags | gpt-4o-mini | Auto tags | **No API Key**: Falls back to keyword search, core features remain functional. ## Data Storage - **LibSQL**: Notes, version history - **Vector Index**: Semantic search - **Path**: `data/yiliu.db`, `data/vectors.json` ## Architecture ``` yiliu/ ├── src/ │ ├── index.ts # Entry │ ├── commands/ # Command handlers │ ├── storage/ # Storage (LibSQL + Vector) │ ├── ai/ # AI capabilities │ └── types/ # Type definitions ├── data/ # Data directory └── SKILL.md ``` ## Version History - **v1.2.0** (2026-03-20) - LibSQL, semantic search, AI enhancement, local embeddings - **v1.0.0** (2026-03-19) - MVP release ## License MIT License
