Circuit

Circuit is a private, local-first media library for Windows—built for people who want one beautiful place for their movies, shows, music, audiobooks, books, and everything else.

Your files stay exactly where they are. Circuit does not upload, rename, move, or lock away your media. Import a few files or an entire multi-drive collection and browse everything through a fast, customizable interface.

Make Circuit yours

Choose from multiple themes, accent colors, interface scales, card sizes, artwork styles, spacing options, and page backgrounds. Circuit adapts its logo and interface accents to your selected personalization.

The Home page brings together Continue Watching, audiobook resume, local recommendations, recently added media, music shuffle, and the Movie Wheel—a visual way to let Circuit choose tonight’s movie.

Built for real collections

Circuit is designed to remain responsive as libraries grow.

• Fast, virtualized browsing for large libraries
• Drag-and-drop importing and organization
• Right-click media actions
• Favorites and custom collections
• Browser-style back and forward navigation
• Search, sorting, filtering, and adjustable views
• Assisted metadata matching through TMDB, MusicBrainz, Cover Art Archive, and Open Library
• Artwork repair and missing-metadata scanning
• Library Health tools for finding moved, missing, or unavailable files
• Automatic relinking when media moves to another drive
• Local backups, recovery tools, crash reports, and diagnostic exports

Private by design

Circuit is single-user, offline-first, and telemetry-free.

Your library database, settings, artwork cache, playback history, and recommendations remain on your PC. Online metadata lookup is optional and only runs when you enable it and request a scan.

No account. No subscription. No cloud library required.

Beta notice

Circuit is actively being developed and tested. Features may continue to change as the interface is refined and larger libraries are tested.

If you encounter a problem, use Circuit’s built-in diagnostic export and include it with your report. Your feedback directly helps make the next beta more reliable.

Circuit does not bypass DRM. Protected Apple, Audible, or other encrypted media must be legally obtained in a playable, unprotected format.
