MatBox is a local-first asset library for creators who need more than folders.
Import your creative files, preview them quickly, and organise them with tags, collections, projects, and goals so the right asset is easier to find when you need it.
Use MatBox to build a searchable home for textures, icons, fonts, sound effects, music, 3D models, materials, shaders, documents, archives, and other project files.
Your library stays on your device, with no account or cloud upload required.
MatBox is designed for artists, game developers, designers, audio creators, and anyone managing a growing set of creative files.
It helps turn scattered folders into a focused library you can browse, preview, and plan around.
