Results
I was losing Saturday night bookings because nobody replied after 8 PM. Customers now book at midnight and wake up to a confirmation. It paid for itself in the first week.
Pricing
No per-message charges. No setup fee. Cancel anytime from the dashboard.
For one location getting started
For busy businesses that live on bookings
For teams and multiple locations
It pays for itself with 4–5 saved bookings a month. Most businesses lose more than that in unanswered messages every single week.
Questions owners actually ask

It only answers from the business information you approve during setup — it doesn't invent prices or promises. Anything it's unsure about, it politely takes the customer's details and alerts you to follow up.
