Linux/Windows Setup
The bundled sqlite-vec and yt-dlp binaries are macOS-only. For other platforms:
sqlite-vec (required for vector search):
- Clone https://github.com/asg017/sqlite-vec
- Build for your platform
- Place at
vendor/sqlite-extensions/vec0.so(Linux) orvec0.dll(Windows) - Set
SQLITE_VEC_EXTENSION_PATHin.env.local
yt-dlp (required for YouTube extraction):
- Download from https://github.com/yt-dlp/yt-dlp/releases
- Place at
vendor/bin/yt-dlp 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.
