AI documentation tools help teams write, update and search their documentation, and the most useful ones help with the hardest part: keeping docs correct after things change. Writing a guide once is easy. Finding the eleven places that still describe last year's process is where documentation usually falls behind. This guide covers the main kinds of AI documentation tool and a workflow for writing and maintaining team docs with AI.
Three Kinds of AI Documentation Tool
- Generated from code. Tools that read a codebase and produce or update reference documentation. Useful for API and code-level docs.
- AI on top of a wiki or help center. Knowledge bases that add AI search and answers to the content you already publish. Useful for helping people find things.
- AI document editors. Editors where AI drafts and edits the documents themselves, from your instructions. Useful for the docs people write: processes, policies, guides, onboarding, specifications.
Many teams use more than one. Fable (fable.la) is the third kind: a desktop AI document editor for Mac and Windows where a team keeps related documents together in projects.
Writing Team Docs with AI in Fable
1. Start from what you have
Import existing docs (Word, PDF, Markdown or text files) into a project, one document per file, with headings and tables kept. Or start from a blank document; new documents also offer templates such as Product Specification and Meeting Notes. See import and export.
2. Say what to write
Type or speak an instruction: "Write an onboarding guide for new support staff: accounts they need, the first-week schedule, and who to ask for what." Speaking is useful for subject experts who know the process well and would rather explain it than type it. See editing with AI.
3. Review as a team
Invite colleagues as Editors to write alongside you, or as Viewers who leave typed or spoken suggestions on specific passages for the owner to accept or reject. Changes sync between collaborators as they happen. See collaboration.
4. Find what is out of date
When something changes, ask the project assistant: "Which documents still describe the old expense approval process?" It searches every document in the project, including by meaning when the exact words differ, and tells you which ones are affected.
5. Update everything at once
Then ask for the fix: "Update them to say approvals go to the finance lead, not the office manager." The assistant proposes the edits across all the affected documents as diffs, and nothing changes until you approve. Every change is saved to the version history with its author, so any document can be restored to an earlier version.
6. Publish
Share a public link that opens a document in a browser, or export to Markdown, HTML, DOCX, PDF or text for your docs site, wiki or help center.
Tips for Documentation That Stays Useful
- Give every doc an owner. Unowned docs are the ones that go stale.
- Write the task in the title. "How to request a laptop" is easier to find than "Hardware."
- Keep one source of truth. Link to the canonical doc rather than copying its steps elsewhere.
- Date your reviews. A "last reviewed" line tells readers how much to trust a page.
- Make updating part of the change. When a process changes, updating the docs is part of the same task, not a follow-up.
When to Use Which
If you need reference docs generated from code, use a tool built for that. If your main need is helping people search an existing help center, AI search on that knowledge base is the right fit. If the work is writing and maintaining the documents themselves, as a team, with a history of every change, an AI document editor like Fable fits.

Frequently Asked Questions
What is an AI documentation tool?
An AI documentation tool uses AI to help write, update or search a team's documentation: how-to guides, policies, onboarding docs, product and process documentation. Some generate docs from source code, some add AI search to a wiki or help center, and some, like Fable, are document editors where AI drafts and edits the documents themselves.
Can AI keep documentation up to date?
It can do much of the work. When something changes, an AI assistant that can read all of your docs can find every place that mentions it and propose the updates. A person still has to tell it what changed and approve the edits, because only your team knows which version is now true.
Does Fable generate documentation from code?
No. Fable does not read code repositories. It is for written documentation that people author: process docs, guides, policies, onboarding material, specifications and similar documents.
Can I publish documentation from Fable?
You can share a public link that opens a document in any browser, and you can export documents to Markdown, HTML, DOCX, PDF or plain text to publish in a docs site, wiki or help center. Fable does not host a documentation website itself.
