I built a guest guide that refuses to make up an answer

I’ve been building Askello, a guest guide for short-term rental hosts, and I want to write about one specific decision rather than pitch the whole product.

Every host answers the same questions repeatedly:

- What’s the Wi-Fi password?

- How does the oven work?

- Where can we park?

- What time is checkout?

The obvious solution is to put everything in a document and send guests the link. Hosts already do that with PDFs, laminated sheets and long check-in messages. But nobody reads an entire manual at 11pm when the oven won’t light.

With Askello, a host pastes the information they already give guests. AI organizes it into editable sections, the host reviews and publishes it, and guests receive a mobile guide they can browse or ask questions to.

The part I spent the most time on is what happens when the guide doesn’t contain an answer.

The easy but dangerous version is a chatbot that responds using general knowledge about apartments. That becomes a serious problem when it confidently invents a checkout time, parking instruction or door code.

Askello’s assistant receives only the property’s published guide. If the answer isn’t there, it says so and directs the guest to the host. The unanswered question is recorded so the host can add the missing information once.

It’s live and free for one property, with no card required. The free plan includes the complete guide, QR sharing and 14 days of AI answers.

Here’s the fictional sample guide, including the question box:

I’d especially value feedback from anyone who has tried using AI for guest questions or customer support.

What failed, and what made you stop trusting the answers?
