How to actually do it
- Open your current pricing, delivery, returns, complaints, warranty, account and product documents, and remove superseded versions.
- Put the documents in one clearly labelled folder and add the document title, version or review date to each file.
- Paste or upload the folder contents into a document-question answering tool, then add the prompt above with your business name and contact method.
- Ask the tool ten real customer questions, including questions about prices, exceptions, refunds, delays and information missing from the documents.
- Compare every answer and citation with the named source document, correcting the document or prompt where the answer is unsupported, vague or out of date.
- Set an escalation route for unanswered, conflicting, sensitive or complaint-related questions, then connect the tested assistant to your chosen customer channel.
- Send a small set of live questions through the customer channel and compare the displayed answers with your approved documents before wider publication.
Prompt
You are answering customer questions for [BUSINESS NAME] using only the business documents pasted or uploaded below. Do not invent facts, prices, delivery times, guarantees, policies or exceptions. If the documents do not contain the answer, say: "I cannot confirm that from the information available. Please contact [CONTACT METHOD]." Do not infer an answer from general knowledge. Give a short, plain British English answer, then cite the exact document title and section used. If documents conflict, do not choose between them. State that the information conflicts and direct the customer to [CONTACT METHOD]. Do not collect unnecessary personal data, ask for payment details, or make commitments that are not stated in the documents. Documents: [UPLOAD OR PASTE CURRENT BUSINESS DOCUMENTS]

What it gets wrong
- It cannot know whether a document is still operationally true unless you keep the source material current.
- It cannot reliably resolve conflicting policies or decide when an unusual customer deserves an exception.
- It cannot carry the business responsibility for an inaccurate promise about a refund, delivery, warranty or price.
- It cannot replace human handling for complaints, distress, negotiation or questions requiring account-specific judgement.
- It cannot make exhaustive checking cheap once your documents and customer questions become numerous.
Even on a YES, the friction has a name: real time truth, judgement under ambiguity and verification cost.

FAQ
- Can AI answer customer questions from a PDF?
- Yes, if the PDF contains the relevant and current information and the tool can read its text. Test the answers against the exact sections, because a PDF with missing, conflicting or outdated content produces unreliable customer replies.
- How do I train an AI chatbot on my business documents?
- Upload or connect your approved documents to a document-question answering tool, then instruct it to use only those documents and cite its source. Test real questions, define an escalation route and update the documents when your policies change.
- Can AI answer customer questions without making things up?
- You can reduce made-up answers by telling it to use only your documents, cite the source and say when the answer is missing. You still need to test it, because the business remains responsible for answers that make unsupported promises.
- What is the best AI tool for answering questions from my documents?
- CustomGPT is a suitable option because it creates a custom chatbot from your business content and provides citations. Other listed options include DocsBot, SiteGPT, Chatbase and Tidio Lyro, so the right choice depends on where you want customers to ask questions and how much control you need.
