If you've ever tried to maintain consistent visual design across different AI tools or design workflows, this is worth checking out. It lets you create, extract, or apply a portable design system using a single visual-style.md file that captures colors, typography, layout, motion, and mood. You can extract styles from existing URLs, images, or videos, then apply them wherever you're working. The workflow is straightforward: create from scratch with prompts, pull from existing sources, or browse a gallery of examples. It's from HeyGen and has passed most security audits. Honestly feels like someone finally solved the "design tokens but for AI agents" problem in a practical way.
