Gingersauce

Gingersauce is an online platform designed for designers and businesses to quickly create professional brand books. It automates many aspects of brand guideline creation, allowing users to upload assets, define colors and fonts, and generate shareable brand guides. The platform aims to streamline the process of presenting brand identities to clients and ensuring brand consistency.

Gingersauce is a strong match for the concept. It explicitly offers a 'Brand Book Builder' which is an online tool to create and share brand books. The website mentions storing 'books & assets online' (centralized-asset-storage), the ability to 'customize every element of your brand book' (brand-guideline-editor, customizable-sections), and that 'Our brand books are easy to exchange and share' (shareable-brand-guide-url). It also highlights features like 'offer logo and icon variations' (logo-variant-upload), 'pull up your color palette' (color-palette-definition), and 'choose fonts' (typography-settings). The 'Preview Mode' is implied by the ability to instantly see changes and generate a brand book ready to be sent. While version control isn't explicitly stated, the nature of an online editor implies updates are handled.
