Xtensio

Xtensio is a platform for creating, managing, and sharing 'living documents,' including brand guidelines. It provides customizable templates, centralized storage for brand assets, and collaboration tools, allowing users to maintain consistent branding across various business and marketing materials.

Xtensio offers a 'Brand Guidelines Template' that allows users to create, manage, and share living brand documents. It explicitly mentions features like adding existing branding elements, sharing live documents (no more outdated PDFs), and applying brand guidelines to other business documents. The pricing page details features such as 'Customize fonts and colors (your style guide)', 'Upload your own fonts', 'Upload your own logo', 'Unlimited image storage', and 'Collaboration' with real-time syncing. These directly align with the must-have features of centralized asset storage, brand guideline editor, shareable URL, and version control. The platform also supports asset organization through its 'Team Style Guide' and the ability to add various sections, defining color palettes and typography, and offering Google and custom fonts. The 'Preview Mode' is implied by the 'Live like a website' and 'Edit and publish online' descriptions.
