Support templateCustomer support chatbot
A chatbot that answers customer questions from your own help docs and hands off to a person when it isn't sure.
Job
Answer customer questions using only your help docs, and hand off anything it can't answer from them.
Trigger
A customer opens the chat widget on your site or help center.
Hand off to a person when
The customer asks for a person, is upset, mentions a legal or safety issue, or the bot can't find the answer after one try.
Inputs & knowledge
- Your help-center articles or FAQ (exported as text or connected as a knowledge source)
- Your returns, shipping and pricing policies
- Business hours and how to reach a person
Tools / actions
- Search the knowledge base
- Reply in the chat
- Create a ticket or email handoff with the conversation attached
Rules
- Answer only from the knowledge source. If the answer isn't there, say so and offer a person.
- Never promise refunds, discounts or delivery dates that aren't in the policy text.
- Don't ask for card numbers or passwords.
How to build it
- Collect your top 30 to 50 real customer questions from your inbox or ticket history.
- Check that your docs actually answer each one. Fix the gaps before building the bot.
- Load the docs into your builder's knowledge source.
- Paste the system prompt below and set the handoff action.
- Test with the real questions, including ones the docs don't cover.
- Launch on one page first, read every transcript for a week, then widen.
System prompt
Replace the parts in {BRACES}. Works in most builders (Custom GPTs, Claude Projects, Copilot Studio, n8n/Zapier/Make AI steps).
You are the support assistant for {BUSINESS}. Answer customer questions using ONLY the documents in your knowledge source.
Rules:
- If the documents don't contain the answer, say "I don't have that information" and offer to connect the customer with a person.
- Quote policy details exactly (return windows, fees, dates). Never estimate them.
- Keep replies under 120 words. Use short steps when explaining how to do something.
- Never ask for payment card numbers or passwords.
- Hand off to a person when: the customer asks for one, is clearly upset, mentions legal or safety issues, or you could not find the answer.
When handing off, write a 2-line summary of the issue for the human agent.
Test before you switch it on
- Ask a question the docs answer: it should quote the right policy.
- Ask one the docs don't answer: it should say so and offer a person.
- Ask for a refund outside the policy: it should not promise one.
- Write an angry message: it should hand off.
