luca and DialogShift are both German providers, and they solve problems of different breadth. DialogShift is an AI platform for guest communication, built on a central knowledge base. luca is a guest experience platform where communication is one module alongside check-in, payments, POS, upselling, and kiosk. This page compares both fairly so you can pick what fits your property.
One platform instead of an AI layer
DialogShift is focused on one job: guest communication by AI. The central AI database learns from PDFs, websites, and FAQ catalogs, and answers questions on the website, WhatsApp, and social around the clock, at roughly 95% automation per the provider. Several further modules such as Phone AI, Email AI, and Journey Messaging AI are marked "coming soon" on the website.
luca covers communication too, through luca Chat and the luca Inbox. Alongside it sit online check-in, the digital guest directory, digital keys, upselling, kiosk, reservations, and payment in the same system, and those modules are live today. Vienna House by Wyndham Andel's Berlin, with over 550 rooms, runs exactly this full setup.
Payments and restaurant POS belong to the system
The clearest difference is transactions. DialogShift drives conversations and passes bookings to a connected booking engine. An integrated payment processor and a point-of-sale are not part of the product.
luca processes payments itself. luca Pay runs on Adyen, with less than 1% on all cards and no subscription. For F&B, a real POS comes with it: order and pay at the table, at the pool, or in the room. At Isla Brown Corinthia, Curio Collection by Hilton, luca created 180 additional order points this way and brought in €12,500 of extra F&B revenue in a single month.
Communication that is tied to operations
Both systems answer repeat questions automatically. luca connects communication directly to operations: from a guest message like "please send fresh towels," luca Chat creates a task for the team automatically. Every written message, whether email, WhatsApp reminder, or chatbot history, lands in the luca Inbox in one thread per guest, with no extra login.
Both providers are German companies operating under German GDPR. The difference lies in scope: DialogShift goes deep in conversational and voice AI, while luca connects communication, payment, check-in, and upselling in one system.
When DialogShift is the better fit
DialogShift is a strong specialist tool, and in some cases the better choice.
- You want to keep your existing setup. If PMS, payment, and operations are set and you only want to add a proven German AI chatbot on the website, DialogShift is built for exactly that.
- Conversational and voice AI are the priority. DialogShift leans hard into AI across several channels and names well-known chains as references, including Motel One, Althoff Hotels, and Sonnenalp.
- You want to start at a clear entry price. The AI database starts at €200/month per the provider, with add-ons as needed (as of July 2026).
