Guest messaging software built for hotels.
Guest messaging software is one inbox where every message a guest sends arrives together, whatever channel it came from, with the reservation attached. It is not a helpdesk: there are no tickets, only conversations. chatlyn brings WhatsApp, email, webchat, Booking.com, Instagram and Messenger into that one screen, connected to your PMS.
Trusted by 1,000+ hotels worldwide
Every missed message is a missed booking.
What is guest messaging software?
Guest messaging software collects every channel a guest might write on into a single inbox and keeps the reservation beside the thread, so whoever picks it up can answer properly. The distinction that matters for a hotel: it is not a helpdesk. There are no tickets to open and close, only a conversation with a guest that continues across the stay. A booking confirmed, an upgrade sold, a five-star review earned: each one starts as a message someone answered in time.
Every channel your guests use.
WhatsApp, email, Booking.com, Instagram, Messenger, and webchat in one inbox your whole team shares. No app-switching, no missed messages, and unlike WhatsApp Business' 5-device cap, no user limit.

Assign conversations, set who is available, and tag with labels by topic, urgency or department. Response-time targets sort the queue into 5, 15 and 30 minute tiers, so the thread closest to breaching is the one at the top. When the night shift hands over, the full history is already there, with no messages asking who replied to room 412.

Questions about the inbox.
Guest messaging software is one inbox that collects every channel a guest writes on and keeps the reservation beside the conversation. For a hotel the useful part is the context: whoever opens the thread can see the stay, the previous messages and the guest's language without leaving the screen.
WhatsApp (Business API), email (Gmail, Outlook, IMAP/SMTP), webchat, Booking.com, Instagram and Facebook Messenger, all in one inbox. SMS exists as a one-way fallback for notifications only: guests cannot reply to it, so it is not a conversation channel.
A helpdesk models the work as tickets that open and close. A stay does not work that way. chatlyn keeps one continuing conversation per guest across channels and across visits, so a question before arrival and a request on the third night sit on the same thread rather than in two unrelated tickets.
No, and the difference is deliberate. The AI replies on its own on WhatsApp and webchat. On email it drafts a reply and waits for someone to send it, which is a hard product rule rather than a setting. Booking.com AI handling is in rollout.
Yes. chatlyn is built and hosted in the EU, the AI models run EU-hosted with a PII-masking layer, and there is no direct connection to an external LLM. Guests are told an AI is handling the conversation, as the EU AI Act requires.
Yes, with no user limit. Front office, reservations, concierge, housekeeping and management work in the same inbox under agent, manager and admin roles. Conversations carry a single assignee so two people never answer the same guest. The St. Regis Le Morne runs 30+ butlers on one WhatsApp number this way.
