GitBook is an editor-first docs platform priced per site and per editor; Docsbook publishes the Markdown in your GitHub repository and prices per project.
Both host your docs, sync with GitHub and serve llms.txt and an MCP server; they differ in how you edit, how you pay, and what the AI does after the site is live.
- $20
- a month per project for Docsbook Pro, AI usage included
- $65
- per site a month for GitBook Premium, billed annually
- $12
- per extra GitBook user a month; Docsbook adds no seats

How does the pricing compare?#
The two bills grow with different things. GitBook charges per site and per editor; Docsbook charges per project and meters AI usage.
- GitBook Premium — $65 per site a month billed annually, plus $12 per user a month for additional users.
- GitBook Ultimate — $249 per site a month billed annually; this is the tier with the AI Assistant chat.
- Docsbook Pro — $20 a month per project; the $20 comes back as AI usage for chat answers, agent runs and translations.
- Docsbook Enterprise — arranged with the Docsbook team, with one balance everyone on the project spends.
On Docsbook, anyone who can push to your repository can edit the docs, so adding an engineer adds nothing to the bill. Details are on Plans and pricing.
What happens after the site is live?#
Hosting is the part both do. On Pro, Docsbook's agents keep working after publishing: they read what your readers and the AI engines do, check pages against 299 published rules, and send the fix as a pull request.
- A search found nothing — the Write the pages readers wanted trigger writes the missing page.
- The AI chat could not answer — Answer what the chat could not adds what the page was missing.
- An AI engine cites someone else — Do AI engines cite you asks the answer engines every week and fixes what it can.
- The code moved on — Find pages the code outgrew catches pages that stopped being true.
Each change carries a reason and a date to check the result. Find wins fast explains how the agent picks what to do first.
When is GitBook the better choice?#
GitBook fits teams whose editors do not work in Git. Pick it when one of these is true:
- Most editors are not developers — GitBook's block editor and real-time collaboration (Premium and up) are built for them.
- You review inside the editor — change requests and version history are on every GitBook plan.
- You need SAML SSO for your team — GitBook packages it on Enterprise.
- You are on GitBook and it works — moving has a cost, and a happy team is a reason to stay.
When is Docsbook the better choice?#
Docsbook fits teams whose docs already live next to the code. Pick it when:
- Your Markdown is in GitHub and you want no second system of record.
- You want an AI chat for readers without an enterprise-tier price.
- You want the docs to improve on their own — you tell the agent what you want in one sentence, from Claude Code, Cursor or the panel chat (Get discovered).
- You sell in several languages and want each translated page indexed at its own URL.
FAQ#
Does GitBook have an MCP server and llms.txt?
Yes: as of September 2026, GitBook's pricing page lists llms.txt, llms-full.txt, Markdown versions of pages and an MCP server on every plan. Docsbook generates the same for every site; see llms.txt and Markdown for AI.
Can I keep editing in GitBook and publish with Docsbook?
You can, but GitBook's Git Sync is two-way, so two tools would write to one repository. Pick one place to edit; if it is GitHub, follow Migrating from GitBook to Docsbook.
Is Docsbook free?
Every account gets one 14-day Pro trial with $5 of AI credit and no card. Without a plan afterwards the site stays published; the AI chat, agents, translations and analytics views switch off until you subscribe.
Can I remove the Powered by Docsbook badge?
No. Every Docsbook site shows a small Powered by Docsbook badge, on every plan.
