An AI concierge for your guests: scope, sources and handover

An instruction to use a knowledge base cannot guarantee a correct answer. Test missing information, conflicting dates, misleading messages and requests to change reservations. Keep prices and availability in the booking system. Show that the assistant is AI, and give guests a working contact option. Before launch, document the application host, model provider, logging, retention and access. An EU web server alone does not establish where a model processes messages.

What "Trained on Your Own Data" Actually Means

When people hear "AI assistant," they often picture something that makes things up confidently, and that fear is reasonable, because many off-the-shelf chatbots do exactly that. The setup I use is different. It is built around a knowledge base: a simple text file (or markdown document) that you write and maintain, containing exactly what you want the assistant to know. Check-in times, your Wi-Fi password, breakfast options, how to reach your place from Merano, local hiking and ski tips specific to your area of Val Venosta or the Dolomites.

The System Prompt: Rules the AI Follows

Alongside the knowledge base, the assistant receives a system prompt, a short instruction file that defines how it should behave. This is where you set the rules: only answer from the knowledge base, respond in the guest's language, escalate certain topics to a human, and never make up booking details. Below is a compact example of what that looks like in practice.

What It Does Not Do, and Why That Matters

1. Write your knowledge base, one document covering check-in, Wi-Fi, breakfast, local tips, and FAQ.
2. I configure and deploy the assistant on your website and optionally on WhatsApp.
3. You test it as a guest would, adjusting anything that needs refinement.
4. Go live. Update the knowledge base yourself whenever anything changes.

The assistant answers from what you have written. If you changed your breakfast hours last November and forgot to update the file, guests will get the old time. This is the one discipline the system requires: treat the knowledge base like your check-in sign. When something changes at the property, update the file the same day. It takes two minutes.

Is This for You?

If you run a hotel, B&B, or holiday apartment in South Tyrol and you find yourself answering the same guest questions on evenings and weekends, this is worth a conversation. It does not require you to understand AI systems. It requires you to have your property information written down, which you probably already do, scattered across a few documents. I put it into a single knowledge base, configure the assistant, and you get the benefits without the complexity. If you want to see what it would look like for your specific property, contact me and I will put together a concrete example using your actual information.
