Docup vs GitBook
How Docup and GitBook compare: generating docs from a repository versus a documentation platform with Git Sync and AI features, and what each costs.
On this page
The short version
GitBook is a documentation platform with a web editor, Git Sync for managing docs with code-style workflows, and AI features. Docup is narrower: it writes the documentation from a GitHub repository and updates the affected pages when the code changes.
What we say about GitBook comes from its official site on November 3, 2026. It can change, so check gitbook.com and its pricing page for the current details.
What GitBook says it offers
- Git Sync, to branch, review and merge documentation like a pull request.
- GitBook Agent, which scans for content that no longer matches your product and flags it for review.
- AI Assistant for readers' questions, and AI Insights on where users and agents get stuck.
- A free plan for individuals, Essential at $65 per site per month, Ultimate at $249 per site per month, and custom Enterprise pricing. Paid plans are billed annually, with extra users at $12 per user per month.
Where Docup fits
- You want the first draft written from the code rather than written by hand.
- You want outdated pages rewritten from the new code, not only flagged.
- You prefer one connected repository and a hosted site over a general documentation workspace.
- You want to pay nothing during early access.
Where GitBook may fit better
- Your documentation is more than a project's code docs, such as company knowledge, with several editors.
- You need enterprise features such as SSO and compliance certifications, which GitBook lists. Docup does not list them.
