Personal messages start with knowing the guest
Most tools only see the message in front of them. chatlyn sees the guest behind it, and puts that knowledge to work in every reply and every message along the stay.

One guest, one profile, whichever channel they write on
An email before booking, a Booking.com message about early check-in, WhatsApp during the stay: chatlyn keeps it all on one profile, next to the bookings from your PMS.
Whoever picks up the conversation sees who the guest is, when they arrive and what they asked last time. Duplicate profiles merge in a click.
No guest waits, nothing slips through
Every conversation has one owner and a clear status. New conversations go to whoever is online, and response-time targets per channel show what needs an answer first.
Notes and mentions stay inside the team, and a snoozed follow-up comes back on its own. There is no device limit: your whole team works on one WhatsApp number, from the desk or the mobile app.
In the guest’s language, day and night
At 23:00 the AI answers on WhatsApp and webchat from your hotel’s own knowledge, in the language the guest writes in. When a person is needed, it hands over with the whole conversation.
Your team reads every message in their own language and replies in the guest’s. On email the AI only drafts: a person always sends.
Your PMS brings the booking into every conversation
Bookings, stays and spend flow from your PMS into chatlyn, so every thread shows who the guest is and when they stay. The same data times the confirmation, the pre-arrival welcome and the farewell on WhatsApp.
The connection is read-only: chatlyn reads your bookings and never changes anything in your PMS. Our team sets it up with you.

Questions about guest messaging software.
Guest messaging software brings every message a guest sends into one inbox, whatever channel it came from, so your team can answer it properly. chatlyn also holds each guest’s bookings from your PMS and every earlier conversation, so every reply is personal and on time.
WhatsApp, email, webchat, Booking.com, Messenger and Instagram, all in one inbox your whole team shares, with every conversation on the guest’s profile.
A helpdesk opens and closes tickets. A hotel talks to the same guest before, during and after the stay, so chatlyn keeps one ongoing conversation per guest, with the booking beside it, instead of a pile of tickets.
On WhatsApp and webchat the AI answers by itself, from your hotel’s own knowledge and in the guest’s language. On email it drafts replies and a person always sends them.
When a guest asks for a person, or the AI is unsure, the conversation goes to a team member who is online, with the full conversation. Anyone can take over from the AI at any time.
chatlyn connects to PMS systems including Oracle OPERA Cloud, Mews, Apaleo, Protel, Guestline and Clock. Booking data flows one way, from your PMS into chatlyn, so nothing in your PMS is changed.
Yes. Your team reads guest messages translated into their own language and writes replies that are translated into the guest’s language before they are sent.
As many as you need. Users are unlimited, with agent, manager and admin roles, and the mobile app for iOS and Android keeps your team answering away from the desk.
Yes. The chatlyn platform is hosted in Frankfurt, and personal data is masked before any request reaches an AI model. Properties with stricter requirements can opt into EU-only AI processing.
In weeks, not months. The exact timing depends mostly on your PMS, since some providers set up the interface on their side first. Our onboarding team sets up the inbox, channels and AI with you.
The inbox is one part of chatlyn.
