Overview
GitBook
GitBook is a developer documentation platform that syncs two-way with GitHub and GitLab. It combines a docs-as-code workflow with a block-based WYSIWYG editor, making it popular for SDK docs, API references, and internal engineering wikis.
KnowUp
KnowUp uses an autonomous browser-based AI agent that logs into your product, navigates it like a real user, and drafts complete help-center articles with screenshots — without anyone pressing record. It also detects UI changes and proactively updates existing docs.

What is GitBook?
GitBook is a modern documentation platform built for technical teams. It offers two-way Git synchronization so developers can edit docs in their IDE and push changes through their normal code workflow. Non-technical contributors can use the built-in block editor. GitBook is widely used for API documentation, SDK guides, internal engineering wikis, and open-source project docs.

Key differences between KnowUp and GitBook
GitBook is a documentation authoring and hosting platform — teams write content manually (via Git or the editor) and GitBook publishes it beautifully. KnowUp's AI agent creates and maintains documentation autonomously. GitBook excels at developer-facing docs with Git workflows; KnowUp excels at customer-facing help centers for UI-based SaaS products. GitBook requires humans to notice and update outdated content; KnowUp detects UI changes and updates articles proactively.
