PlexMix

What PlexMix is

PlexMix creates personalized playlists from a Plex music library using natural-language mood descriptions. It syncs music metadata to a local SQLite database and generates semantic embeddings for tracks. Playlist generation can use filters for genre, year, rating, artist, environment, instrument, tempo, energy, key, and danceability, with similarity, random, alternating-artist, or energy-curve ordering. Optional Essentia analysis extracts audio features such as tempo, key, energy, danceability, and loudness; optional MusicBrainz enrichment adds community-curated genres, canonical artist IDs, and recording-type detection. Playlists can be exported as JSON or M3U, or imported from files with track matching. PlexMix supports multiple cloud AI providers and local models; cloud providers require an API key and internet access, while local embedding models run offline. It can create Plex playlists when enabled and does not modify or delete tracks, albums, or artists. The project is free, open source under GNU AGPL v3, and available for Linux, self-hosted use, and the web. Its web UI is alpha; the README recommends the CLI for production use.
