The guest requests.
stayi sorts it out.
stayi is the AI concierge that takes action in the real world. It calls the taxi, books the table, sends up the towels, in every guest’s own language. Your team learns nothing new.
The difference
Others tell your guests how to solve a problem. stayi solves it.

Guest told, in Italian. Reception sees it on one screen.
Straight from the guest’s phone. A local concierge in their pocket, from check-in to check-out.
Voice or text, in their language. They speak the way they’d speak to a person.
Your team stays in charge. Every request on one screen. Step in whenever you want.
Why stayi
AI, with manners.
Hospitality is a craft, and most technology forgets it. stayi was built by a hotelier, for his own rooms in Athens, because nothing on the market looked after guests the way a real person does. So stayi behaves like your best concierge: quick, discreet, never in the way.
“I wanted help that feels as much as possible like what a real person would give. Nothing came close, so we built it.”Panos Terzopoulos · Founder

Tomorrow’s sunset cruise has two seats left. Shall I hold them for you?
Revenue
It sells, politely.
stayi suggests extras at the right moment: the late checkout, the sunset cruise, the bottle waiting on the table. It makes the stay better, and always speaks the guest’s language.

What is stayi?
stayi (said “stay-eye”) is the AI concierge for hotels and holiday homes. Guests ask by voice or text, in their own language, and stayi calls the taxi, books the table, sends a message to housekeeping. Your team sees every request on one screen.
How is stayi different from a hotel chatbot?
A typical AI assistant gives guests information and leaves the rest to them. stayi finishes the job: it makes the call, confirms the booking and tells the guest when it’s done.
What can stayi do for guests?
Anything you would ask a great concierge, as long as it’s possible: the 6am airport taxi, a table with a view, breakfast in bed, a boat trip, extra pillows, sunbeds for the sunset. It calls local partners, makes bookings and sends messages to your team.
Do we need to buy devices or install anything?
No. stayi runs on your guests’ own phones. Each room has its own QR code, printed once, and each stay gets its own code at check-in. There are no devices to buy and nothing to install.
Which languages does stayi speak?
It speaks with every guest in their own language, by voice or text, day and night.
Does our team need training?
No. There is nothing new for your team to learn. stayi works on its own and takes the small requests off their hands, and your team stays in charge: every request is on one screen, and they can step in whenever they want.
Who sets stayi up?
stayi does. Our assistant asks you a few questions about your hotel, and stayi sets everything up. It is trained for your island, your city, your street.
Can stayi increase a hotel’s revenue?
Yes. stayi offers your extras at the right moment, like the late checkout, the sunset cruise or the bottle waiting on the table, and only when it makes the stay better. It can also cross-sell the best of the area through partner bookings. Every booking shows up on your screen.
Is stayi only for hotels?
No, holiday homes too. Each home gets its own QR code, at the same price per room.
How much does stayi cost?
One price per room, everything included: €16.90 per room per month for 1–20 rooms, €14.90 per room per month for 21–50 rooms, and a custom price over 50 rooms, plus VAT. 10% off for 6 months paid up front, 20% off for a year paid up front. The first 30 days are free.
We only open for the season. Do we pay all year?
No. Pay month by month and stop at the end of any month, then start again when you open. The yearly price is for hotels open all year.
What happens after the free month?
Nothing until day 31. Then the card on file is charged for the plan you chose. Monthly renews each month until you cancel; it stops at the end of that month. The 6- and 12-month plans are paid once, run for 6 or 12 months and end; to continue, you pick a plan again. Cancel before day 31 and you pay nothing.
Who is behind stayi?
stayi was built by a hotelier, Panos Terzopoulos, for his own rooms in Athens. The company behind it is PANTECH SINGLE MEMBER P.C., based in Athens, Greece.
How do we get started?
Start your free month online from the pricing above. Over 50 rooms, or if you’d like to talk first, book a 15-minute call. Or email info@stayi.app.
