GitBook UI design & app screens

GitBook is a documentation platform for technical teams to write, publish, and maintain knowledge bases, product docs, and internal wikis. It targets developers, technical writers, and product teams who want polished, navigable documentation.

The interface pairs a clean, distraction-free editor with strong typography, a left-hand navigation tree, and fast in-doc search. It's a useful reference for content-heavy reading experiences, block-based editing, version control surfaces, and the balance between an authoring view and a reader-facing published site.
