Inside this file

Vellum — Studio Asset Library is a single .gui file — plain-text markup plus its assets in one container. Everything needed to render it is declared in the source, so a renderer or an AI agent can read the structure directly, no screenshots required.

What is a .gui file?

.gui is an open file format for user interfaces — one plain-text file describing a screen's layout, roles, colors and copy. It is built to be read by both humans and AI agents: no proprietary binary, no screenshots to interpret.

Preview any file here, read its source, or download it and render it with the .gui toolchain.
