- An assistant is only as reliable as the information it’s allowed to use.
- Gather your real customer questions first, then write clear, approved answers.
- Decide which topics are off limits, and keep the knowledge base up to date.
Why the knowledge base matters most
An AI assistant can sound helpful about almost anything, which is exactly the risk. The way to keep it accurate is to limit it to a knowledge base: a set of answers you've written, checked and approved. If the answer isn't in there, the assistant hands the question to a person.
Step 1: Collect the questions customers really ask
Don't start with what you think customers ask. Look at real sources:
- Recent emails and website messages.
- Notes from phone calls.
- Questions your front-desk or office staff hear every day.
- Reviews that mention confusion or missing information.
Group similar questions together. Most businesses find a few dozen questions cover the large majority of inquiries.
Step 2: Write clear, short answers
For each question, write the answer as you'd say it to a customer:
- Keep it short and in plain language.
- Include the specific details: times, addresses, prices or ranges, what to bring.
- Say what happens next, such as "you can book online" or "we'll call you to confirm".
- Avoid promises the assistant can't keep.
Step 3: Mark what's off limits
Make a clear list of topics the assistant never answers on its own: pricing exceptions, complaints, emergencies, anything sensitive. For clinics and dental offices, that includes every health or treatment question. The assistant is for administrative questions only.

Step 4: Have the right person approve it
Someone who knows the business well should review every answer before it goes live, checking accuracy, tone and anything that could be misunderstood. Record when each answer was approved and by whom.
Step 5: Keep it current
A knowledge base goes stale quietly. Schedule a regular review, perhaps monthly, and update it whenever something changes: prices, hours, staff, services or policies. Look at the questions the assistant handed off; many will show gaps worth filling.
