SiZo guest concierge: a guest asks for a refund and SiZo routes it to the owner instead of promising one.
Built by owners of 7 Louisville doors Answers from guides you approve Refunds & repairs come to you

See both sides

The guest asks.
You decide.

Guest concierge screen: a refund request gets a clear reply that the owner will review it.

Routine questions get answered. Money questions don't.Wi-Fi, parking and house rules come from that property's guide. A refund request gets a clear "the owner will review this" and lands in your queue. SiZo is set up never to promise money on your behalf.

Watch the 54-second walkthrough

Captioned. A guest asks → SiZo routes it to the owner → the owner replies in the same thread.

Real screens from the SiZo demo. Sample properties, simulated replies.

Guardrails

The fear isn't that it's useless.
It's that it's confidently wrong.

Most tools lead with how much they automate. SiZo leads with what it won't do: guess, promise money, or send before you trust it.

Approved guides

Answers come from the guide you wrote and approved, not your listing page, old threads or the web. If it isn't in the guide, SiZo says so and asks you.

Hard triggers

Refunds, booking changes, maintenance, lockouts, safety, damage and complaints are flagged and sent to you, not answered, however simple they look.

Confidence gate

Below the confidence bar, a reply waits for you. It arrives as a suggestion you approve or rewrite.

Draft-only mode

Every reply starts as a draft. Turn on auto-send for routine questions when you trust it, not before.

The owner app Coming to iPhone

Two taps
from your pocket.

A push when a guest needs you. SiZo says why it paused and drafts the reply. Approve it or edit it, and it goes back into the same guest thread.

  • Why it paused, in one line. "Money is your call."
  • Approve & send, or edit first. Your words win.
  • Draft-only until you say otherwise.
Plus checklists & documentsPhoto proof on turnover steps. Leases and renewals tracked if you also rent long-term.

Questions

Fair questions.

What happens when SiZo doesn't know the answer?

It's built not to guess. Anything outside the property's approved details comes to you as a request, with a suggested reply you can send or rewrite.

Can SiZo reply to guests on its own?

Only for routine questions, and only after you turn off draft-only mode. Anything it isn't sure about comes to you as a suggested reply.

Airbnb already answers some questions. Why SiZo?

Airbnb's auto-replies work from your listing page. SiZo works from the guide you approve, stops when a question needs judgment, and brings refunds, repairs and anything unclear to you with a reply ready.

What does it cost?

Your first listing is free for 30 days, with no card. After that we quote one monthly price per listing, and nothing is charged unless you say yes. Property managers are priced per door.

Are you a property management company?

We own seven doors in Louisville and manage those ourselves. We don't take management clients. We sell the tool.

What do I need to get started?

Your property details. We set up your first listing with you. No sales call required.
