What is Rezi?

Rezi is an AI co-host for Airbnb and VRBO hosts. It answers guest questions instantly, by text message and by phone, using the exact details you give it about each listing. No more answering the same “what’s the WiFi password?” text at 11pm.

If you host short-term rentals, you already know the real job is communication. Guests call about door codes from the airport, message about parking at midnight, and ask about checkout on a Sunday afternoon, and every one of those messages lands on your personal phone. Most of them are questions you’ve answered a hundred times. Rezi exists to absorb that flood so you only deal with the conversations that genuinely need you.

The way it works is simple to describe: each of your properties gets its own dedicated local phone number. Guests text or call that number instead of yours. Rezi answers immediately, around the clock, using a knowledge base you control, the actual WiFi password, the actual trash day, the actual house rules for that specific listing. When something comes up that it can’t or shouldn’t handle, an emergency, a question it doesn’t know, an upset guest, it hands the conversation to you with full context.

What Rezi does for you

• Answers texts and calls 24/7 in the guest’s own language, usually in under two seconds
• Handles check-in and checkout questions and self check-in instructions
• Keeps one availability calendar synced across Airbnb, VRBO, and other channels
• Alerts you to emergencies like a leak or no heat, with the details, so you can act fast
• Escalates to you the moment something needs a human, an emergency, an upset guest, or anything outside its knowledge

Each of those is a full workflow, not just a canned reply. When a guest reports a leak, Rezi asks how bad it is and whether water is actively flowing, reassures the guest, and alerts you right away with the details so you can act fast. When a guest asks about the property, Rezi answers their questions and quotes availability from your synced calendar.

How it actually works

When you set up a property, you give Rezi its knowledge: house rules, check-in instructions, amenities, parking, local tips, and so on. Rezi turns that into a searchable knowledge base. When a guest texts your property’s number, the AI finds the most relevant facts and answers using only your information, never guesses.

That last part matters more than anything else. Rezi is deliberately built to be grounded: if the answer to a question isn’t in your knowledge base, it says so and escalates to you rather than inventing something plausible. A co-host that makes up door codes would be worse than no co-host at all, so the system is conservative by design. You can read more about where the lines are drawn in what the AI can and can’t do.

What Rezi is not

Rezi is not a full accounting suite, a listing syndication tool, or a replacement for your judgment. It won’t change your pricing on its own. It focuses on the communication layer, the texts, calls, triage, and follow-ups that eat your day, and plays nicely alongside whatever back-office tools you already use.

It’s also not an answering service reading from a script. Because it works from your property’s actual knowledge base, it gives real answers, the actual quiet hours, the actual pet policy, and takes real actions like alerting you to an emergency.
