Most wrong AI answers come from missing knowledge, not from the AI. This guide shows how to train your AI co-host with your welcome guide, a private knowledge base and the suggestions Nowistay learns from your own replies, how to set the assistant's tone for each property, and how to test it in draft mode before it replies on its own.

Start free trialThe problem is rarely the AI itself: it is the knowledge behind it. When an AI assistant gives vague or wrong answers to guests, the cause is usually missing, outdated or incomplete property information. With Nowistay, the AI co-host answers from your listing and bookings, your digital welcome guide and a private knowledge base of questions and answers, which Nowistay now enriches with suggestions learned from your own replies. The better that knowledge, the more guest questions the AI handles on its own.
This guide shows how to build that knowledge, what to put in it, how to set the assistant's tone for each property, and how to test it safely before it replies to guests by itself.
The AI co-host combines several sources. Some are automatic: your listing, the guest's reservation details, your bookings calendar and general knowledge, including web searches and real places around your property. The three layers below are the ones you control, and they make the difference.
Everything in your Nowistay welcome guide is synced to the AI's knowledge automatically. You do not need to do anything technical: build a detailed guide and the AI uses it to answer. Check-in steps, wifi, house rules, appliance instructions and your own recommendations all become answers. For everything specific to your property, the guide is the source of truth: without it, the AI cannot guess.
One detail matters: the AI reads your guide in its main language only, the one marked with the star. Guests can read the guide in 9 languages, so keep the main version the most complete and up to date.
To organize the information used by the AI co-host, see the guides to its knowledge sources and private instructions: The AI Assistant’s full knowledge base ; The private knowledge base of the AI Assistant.
The Private knowledge base is a list of question and answer pairs for each property, which you open from the AI button on the property card. It holds what the AI should know but that you do not want in the guide every guest reads: a code you prefer to share only on request, where the electrical panel is, what to do if the hot water fails, or internal instructions such as "never accept a date change without my approval". Write each question the way a guest would ask it, then your answer. Examples:
For each entry, Requires host intervention? decides whether the AI answers alone or alerts you. Turn it on for the topics you want to handle personally: price negotiations, neighbor complaints, damage. If you manage several similar properties, Import from another property copies a knowledge base from one property to another (it replaces the current entries of the property you import into).
The private knowledge base now grows on its own. Every day, Nowistay reviews the conversations where you replied to a guest yourself, typically after the AI asked for your help, and prepares ready-made questions and answers from what you wrote. Suggestions appear at the top of the private knowledge base under Learned from your conversations, each with the sentence it was learned from, and a banner on your messages page tells you when some are waiting.
Nothing is used until you approve it. Click Add to knowledge, after editing the question or answer if needed, or Dismiss: a dismissed suggestion does not come back, and Nowistay only suggests knowledge that your guide and knowledge base do not already cover. Approved answers carry an AI badge and become active for your assistant within about an hour. To start faster, Analyze my past conversations reviews the property's conversation history once.
When a guest asks for the nearest pharmacy, a supermarket or a good restaurant, the AI first uses your welcome guide. If the guide does not cover it, it looks up real places around your property, with the distance, walking time, rating and opening hours, or searches the web. Your own recommendations always come first, so keep your favorite spots in the guide. The AI only shares links that you wrote yourself in your guide or knowledge base, plus Nowistay links: add a restaurant's website or a ticket page to the guide if you want guests to receive it.
The difference between an AI that frustrates guests and one that helps them comes down to what information you give it. Here is a checklist of what your guide and knowledge base should cover:
The AI can find the nearest places by itself; your guide adds what it cannot know, your favorites and why you like them.
In the Assistant config drawer, Assistant tone sets how the AI writes and speaks to the guests of that property. Six tones are available: Warm & professional (default), Friendly & casual, Formal & polished, Concise & efficient, Luxury concierge and Enthusiastic & upbeat. Only the style changes: rules, safety and facts stay the same. Pick the one that matches the property and its guests: a family beach house and a luxury villa should not sound alike. The tone is a setting, so you do not need to describe your style in the knowledge base.
Here is how to go from zero to an AI co-host that knows your property, in five steps.
Step 1: Build a detailed welcome guide
Open Welcome guides in the side menu, or Guidebook on the property card, and fill in every section: property overview, check-in and check-out, wifi, appliances, house rules, local area and emergency contacts. Be specific: write as if you were preparing someone to manage the property in your place. Mark the language you write in as the main language. The AI picks up the guide automatically. For a structure that works, see how to create the perfect Airbnb welcome guide.
Step 2: Add private knowledge for what the guide should not say
Click AI on the property card and open the Private knowledge base. Add the questions your guests ask that need a private or conditional answer, plus your internal instructions. Turn on Requires host intervention? for sensitive topics (price negotiations, neighbor complaints, damage reports) so the AI brings those conversations to you.
Step 3: Review what the AI learned from your conversations
Click Analyze my past conversations once, then review the Learned from your conversations section when new suggestions are waiting. Approve, edit or dismiss each one. Guest-facing information that every guest should see belongs in the guide rather than in the private knowledge base.
Step 4: Set the tone and test in draft mode
Choose the Assistant tone, then set the Reply mode to Draft. The AI then sends nothing to the guest: it emails you the reply it would have sent, and its actions (team requests, booking updates) are not carried out. Read a few days of drafts, check that your guide and knowledge base answer the questions guests typically ask ("How do I get into the apartment?", "Where is the nearest pharmacy?", "The hot water is not working"), fill each gap, then switch back to Automatic. If you prefer to answer yourself at certain times, AI off hours keeps the AI silent during the time slots you choose. All the settings are explained in How to set up my AI co-host.
Step 5: Review and iterate weekly
Each question the AI brought to you is a gap. Your reply can then come back as a suggestion: approve it, and that question is handled without you next time. A short review each week keeps the knowledge current as your property, codes and seasons change.
You write your guide and knowledge base once. The AI co-host replies in the guest's language, in more than 90 languages, and follows the guest if they switch language mid-conversation. Separately, your welcome guide can be read by guests in 9 languages: English, French, Spanish, Italian, German, Portuguese, Russian, Dutch and Chinese.
So a German guest asking "Wo ist der nächste Supermarkt?" gets an answer in German drawn from the details you wrote in English or French. No manual translation and no copy-pasting from a translation tool: the AI uses your own property data, so the answer is specific to your listing. Just keep the main language version of the guide complete, since it is the one the AI reads.
Training your AI co-host is not a one-time task. A simple weekly loop keeps it sharp:
The AI then handles a check-in question at 2 AM, a restaurant request at dinner time or a wifi problem at midnight without waking you, and comes to you only when a human is needed.
Avoid these pitfalls when building your knowledge base:
Build the knowledge it relies on. With Nowistay, your welcome guide is synced to the AI automatically and is the source of truth for everything specific to your property. Add a private knowledge base of questions and answers for what the guide should not say, approve the suggestions Nowistay learns from your own replies, and test in Draft reply mode before letting the AI answer guests on its own.
Include property specifics (wifi, door codes, parking), appliance instructions, your personal local recommendations, house rules, check-in and check-out steps, emergency contacts, common issues and their fixes (for example "the hot water takes 30 seconds"), and seasonal information such as pool hours or heating instructions. The more specific and practical your entries, the better the AI handles real guest situations.
Yes. The Nowistay AI co-host replies in the guest's language, in more than 90 languages, even if the guest switches language mid-conversation. You write your guide and knowledge base once; the AI reads the guide in its main language. Separately, guests can read the welcome guide in 9 languages: English, French, Spanish, Italian, German, Portuguese, Russian, Dutch and Chinese.
It suggests, you decide. Every day, Nowistay reviews conversations where you replied to a guest yourself and prepares question and answer suggestions in the Learned from your conversations section of the private knowledge base. Nothing is used until you click Add to knowledge; you can edit a suggestion first or dismiss it. Analyze my past conversations reviews a property's history once to get started.
Yes. The Assistant tone setting offers six styles per property: Warm & professional (the default), Friendly & casual, Formal & polished, Concise & efficient, Luxury concierge and Enthusiastic & upbeat. Only the style changes: rules, safety and facts stay the same.
Set the Reply mode to Draft. The AI then sends nothing to the guest: it emails you the reply it would have sent, and the actions it would have taken (team requests, booking updates) are not carried out. Read a few days of drafts, fill the gaps in your knowledge, then switch back to Automatic.
