How to Build an FAQ Chatbot from Docs (2026): The Docs Folder First

An FAQ chatbot built from docs answers only from the documents you pointed it at, and it says when those documents are silent. The work is choosing which docs are current, cutting the drafts, and testing questions a real reader asks. The model is last. A bot on a folder of stale specs will quote the stale spec with confidence.

This page is the docs folder: a product guide, an internal handbook, a markdown tree. The customer help center, which is a different corpus, is how to build a knowledge-base chatbot. The pages a human reads, before any bot, are how to create FAQ pages with AI. The method is what RAG is.

Pick the host from who is allowed to see the docs

Who asks	Start here	Price to know	Do not
Employees, and the docs are already in Notion	Notion AI	Business is $20 a seat for the agent on the workspace	Invite customers into the wiki
Readers of a site, and you have a clean doc export	Chatbase	Hobby is $32 a month billed yearly, or $40 monthly, for 700 message credits	Upload drafts, roadmaps, or incident notes
You already pay Intercom and want outcome pricing	Intercom Fin	$49 a month including 50 outcomes, then $0.99 an outcome	Point Fin at a folder you have not cleaned
A small site widget	Tidio Lyro	Standalone Lyro starts at $32.50 a month for 50 Lyro conversations	Treat a widget as a docs site
You are still writing the answers	Claude, then publish the page	Pro is $20, or $17 billed annually	Ship a bot that replaces the missing page

The search under this bot is often an embedding index. You do not have to pick that model if the host hides it. The definition, so you know what a re-index is, is what an embedding model is. The requirement that you can open the passage is what AI grounding is.

Clean the folder before you connect it

Include the pages you would send a colleague today. Exclude drafts, old versions, meeting notes, and anything with a customer name that does not belong in an answer. A bot cannot tell a draft from a policy if both are in the upload. Date the export. When the docs change, update the bot. A nightly copy of a folder nobody owns will drift.

Write the questions you will use as a test, from real tickets or real reader mail, before you admire a demo question. Include questions the docs do not answer. The correct behavior on those is a refusal or a handoff, not a guess. The failure mode is what an AI hallucination is. The person who accepts the bot is what human-in-the-loop AI is.

Chatbase Hobby is the small public bot: 700 message credits a month on the yearly price, and the directory records training on your sources. Standard is $120 a month billed yearly. The step-by-step on that host, aimed at a help center, is how to build a support chatbot with Chatbase. Use the same clicks. Use a docs export, not a scratch FAQ you generated to fill the box.

Notion AI Business is the internal version when the docs already live there. Plus at $10 is not the full AI tier. Do not put customer-facing traffic on a workspace that also holds HR notes. The card is Notion AI pricing explained.

Intercom Fin fits when the docs are already the help center and you want a resolution meter. Fifty outcomes are included in the $49. Extra outcomes are $0.99. A docs experiment does not need that meter. The comparison is Chatbase vs Intercom Fin pricing.

Tidio Lyro is the widget. Starter chat is $24.17 a month annually. Buy it when you need a person to catch the handoff on a small site. The directory’s standalone Lyro price starts at $32.50 a month for 50 conversations.

Claude is how you draft a missing page from source you paste. It is not the bot. Publish the page, then point the bot at the page. The writing method is how to write a blog post with Claude.

FAQ

Can I point a chatbot at the whole drive?

You can, and you will answer from the wrong file. Pick the folder that is the source of truth. A roadmap and a spec from last year are how the bot contradicts the product.

How is this different from a knowledge-base chatbot?

The knowledge-base guide assumes help articles for customers. This one starts from docs: product guides, internal handbooks, markdown. The host can be the same. The corpus rule is stricter, because docs folders collect drafts.

Do I need an embedding API key?

Not if Chatbase, Notion, or Fin is doing the retrieval. You need one if you are building the index yourself. This directory does not record a standalone embedding price. The explainer is linked above.

When should it refuse?

When the docs do not contain the answer. Write that sentence into the bot’s instructions, and test it. A refusal that offers a human is a success. A paragraph that sounds helpful and is not in the docs is a bug.
