Whether day or night.
REPLAI answers.

REPLAI is an AI co-host from Austria for short-term rental hosts. The software brings guest messages from Airbnb, Booking.com, WhatsApp, Instagram, Facebook Messenger, Telegram, email and SMS into a single inbox and answers them automatically — in the host's tone, in the guest's language, around the clock. REPLAI is built in Austria, aimed at the DACH region (Austria, Germany, Switzerland), and currently in closed beta. Access runs through the waitlist at replai.at.

REPLAI is built by Timon Faux (Co-Founder & CEO) and Harald Fuchs (Co-Founder & COO) in Lower Austria. Both come from short-term rental practice — REPLAI grew out of the daily reality of real hosts, not a whiteboard. The project is documented openly: the current state of development is always on the roadmap, including what is not finished yet.

An AI co-host is software that takes over guest communication for a short-term rental host: it reads incoming messages from Airbnb, Booking.com, WhatsApp, Instagram, email or SMS, understands the booking context and drafts a fitting reply. Unlike a human co-host it works around the clock, answers within seconds and costs a predictable flat fee instead of commission. REPLAI is an AI co-host built in Austria for the DACH region.

A virtual assistant is a person who is paid by the hour, needs onboarding, takes holidays and works in their own time zone. REPLAI is software: once configured, it replies every night and every public holiday within seconds, in any language and always in the same tone. Many hosts combine both — REPLAI handles the repetitive standard questions while the VA or the host takes the exceptions.

REPLAI is in closed beta and the final price list is not fixed yet. The plan is a predictable price per property and month — not an hourly rate like virtual assistance and not a revenue share like classic co-hosting. Everyone who joins the waitlist now gets the founder rate for early adopters. Signing up is free and requires no credit card.

Yes, data protection is a foundation of REPLAI rather than an add-on. Every host gets a dedicated database, so there is no shared data storage between customers. The application is hosted in the EU (Vercel, Frankfurt region), the database sits with Supabase in Frankfurt, and the language models run through Azure OpenAI in an EU region. Guest data is never used to train models and is never sold or passed to third parties.

No. Airbnb supports automation in guest communication and even ships a simple version of it with scheduled messages. What matters is that you as the host stay responsible and that the conversation happens on the platform. That is exactly what approval mode is for: the AI drafts, you release. You can take over any conversation at any time.

REPLAI brings Airbnb, Booking.com, WhatsApp, Instagram, Facebook Messenger, Telegram, email (IMAP) and SMS into a single inbox. On the property management side my-bookings.org is connected, and further PMS and channel manager integrations are on the roadmap. Our roadmap shows which connection lands when, with its current status.

Yes. REPLAI detects the language of the incoming guest message and answers in that same language — German, English, Italian, French and more. You keep working in your own language. For hosts in Austria, Germany and Switzerland with an international guest mix this removes manual translation entirely.

It escalates to you instead of guessing. Unusual requests, complaints, price negotiations or anything without sufficient context land as a task in your inbox. On top of that, approval mode lets you review every single reply before it is sent — configurable per property and per channel.

No. REPLAI works standalone and does not require a property management system. If you do run one, results get better: booking data, check-in times and listing information flow into every reply as context automatically. REPLAI does not replace a channel manager, it adds the communication layer on top of it.

Yes — especially when hosting is a side business. With one property the message volume is low, but the messages arrive at the worst possible time: late evenings, nights, holidays. REPLAI answers the same recurring questions about wifi, check-in and parking instantly, so you never reach for your phone. Property managers with many units additionally gain from the pooled inbox.

Exclusively inside the European Union. Each host's database sits isolated with Supabase in Frankfurt, the application runs on Vercel in the Frankfurt region (fra1), and AI requests go to Azure OpenAI in an EU region. Data is encrypted in transit and at rest using AES-256. Regular operation involves no data transfer to third countries.

REPLAI is currently in closed beta with a limited number of seats. The way in is the waitlist: enter your email, confirm the double opt-in, and optionally answer three short questions about your setup. We invite hosts in batches and give preference to those who want to give active feedback.
