About Smily
European operators, direct bookings, high expectations.
Connect Smily and your listings, reservations and guest threads come into ProhostAI, where the AI answers and the work each stay creates gets scheduled.

Smily — previously BookingSync — has a long history with European rental managers, particularly those running a real direct-booking business rather than treating their own site as an afterthought.
That focus raises the stakes on response time. A guest enquiring through your own website has chosen you specifically, and a slow reply reads as indifference in a way it does not on a marketplace where everyone expects a delay.
Connecting Smily means those enquiries get answered immediately, from real availability, in the guest’s language. For a European operator taking bookings across borders, that last part matters as much as the speed.
Bookings and rates stay in Smily throughout. ProhostAI reads them and acts on what they create rather than becoming a second place where availability is decided.

Setup
Smily connects with an API key from your Smily account, so ProhostAI never sees your password.
In Smily, generate an API key from your account settings.
Open ProhostAI and go to Settings → Connections.
Search for Smily, select Connect, and paste the key.
Wait for the first sync, then check your listings and upcoming reservations look right.
Good to know
This connection is in Early Access. It covers listings, reservations and guest messaging rather than every feature the platform offers.
Smily stays the system of record for availability, rates and bookings. ProhostAI reads them and acts on them rather than replacing them.
Direct enquiries carry higher expectations than marketplace ones — a slow reply reads as indifference.
Turn Autopilot on gradually — one property, one message type — so you can judge the AI’s tone before it covers everything.
Questions about Smily
Is Smily the same as BookingSync?

Yes, which for European operators taking cross-border bookings matters as much as the speed.
Is the connection generally available?
It is in Early Access, covering listings, reservations and guest messaging.
