## Features
- **3-Panel interface** Nodes, focus, and chat in one view
- **BYO keys** Your Anthropic/OpenAI keys only; nothing sent to RA-H
- **Local SQLite + sqlite-vec** Semantic search and embeddings on your machine
- **Content extraction** YouTube, PDF, web pipelines included
- **Workflows** Editable JSON workflows for common tasks
- **MCP Server** Connect Claude Code, ChatGPT, or any MCP-compatible assistant

## Linux/Windows Setup
The bundled `sqlite-vec` and `yt-dlp` binaries are macOS-only. For other platforms:
**sqlite-vec** (required for vector search):
1. Clone https://github.com/asg017/sqlite-vec
2. Build for your platform
3. Place at `vendor/sqlite-extensions/vec0.so` (Linux) or `vec0.dll` (Windows)
4. Set `SQLITE_VEC_EXTENSION_PATH` in `.env.local`
**yt-dlp** (required for YouTube extraction):
1. Download from https://github.com/yt-dlp/yt-dlp/releases
2. Place at `vendor/bin/yt-dlp`
3. `chmod +x vendor/bin/yt-dlp` (Linux)
Without sqlite-vec: UI, node CRUD, basic search, chat, and content extraction still work. Vector/semantic search requires it.
