What it does

Everything you need to manage file metadata

A desktop app for tagging, searching, and organizing any kind of file — music, video, documents, images.

🔍

Powerful Search

AND/OR tag queries: rock & metal, jazz | blues
Attribute filters: rating > 5, artist like %Taylor%
Path/filename search with ~ filename
Negation with -tagname
Hierarchical categories with / genre / punk
Saved searches — name and reuse any query
# prefix disables vector search for pure tag/attribute matching

🤖

AI Integration

Built-in MCP server — connect Claude, ChatGPT, and other AI assistants
AI can query, tag, and update your file metadata via a standardized protocol
Vector / semantic search using on-device embeddings — find files by meaning, not just keywords
REST API server — expose your database to external tools and scripts
Both servers can run simultaneously; configurable ports
