Feature highlights
The essentials for filling your calendar — without giving up margin to OTAs.
Knows your property by heart
HostBrain learns your house rules, amenities, seasonal prices, and pet policy. When a guest asks whether the pool is heated in October, it answers in seconds and quotes the exact price for their dates.
You only pay when you win
No subscriptions, no setup fees. A flat five percent applies only when the AI closes a confirmed booking. If it does not earn for you, it costs you nothing.
One calendar, every channel
HostBrain keeps your dates in lockstep with Airbnb and Booking.com. The moment a guest pays, every channel is updated — so a second guest can never book the same nights.
A fairer way to fill your rooms.
OTAs take a sizeable cut and leave the work to you. Here is what changes when guests book through your own site.

What you see
A single dashboard with your master calendar, showing every booking closed by the AI alongside those imported from OTAs like Airbnb and Booking.com. You can also manage seasonal pricing and update what the AI knows about your property.
Why hosts switch to HostBrain
Three quiet shifts that change how you run your rental.
Keep more of every booking
Up to a fifth of every OTA booking goes to commission. HostBrain returns that margin to you, where it belongs.
Reply at any hour, in any language
Guests rarely book the listing that takes ten hours to reply. HostBrain answers in seconds, every day, in the language they are writing in.
Never double-book again
One master calendar, synced everywhere. The moment payment clears, those dates are locked across every channel you are listed on.

"We used to lose two or three direct bookings every week because we could not answer fast enough. That does not happen anymore."

"Setting it up took an afternoon. By the second week we had already paid for it many times over in saved OTA commission."
