# Reply Kindly > Reply Kindly automates NPS and customer feedback after completed bookings, appointments and service visits. Service businesses using bookings or appointments, including salons, clinics, beauty businesses and fitness studios. Booking platforms, appointment software providers and their developers. A visit is the delivered service. Bookings and appointments are the associated records. Feedback is triggered after service completion, not when a reservation is made. Integrations retain the API field externalAppointmentId for the booking reference. AI-assisted report questions: When AI reporting is enabled, ask questions in plain language about NPS, response counts, dates, sites and comparisons. Answers show the reporting periods and sites used. This is report-metric analysis, not a search of customer comments or contact details. Report totals, site labels and your question are sent to Google AI; customer comments and contact details are excluded. This file describes public product information, not access to private customer data. AI report questions require configuration; this file does not establish that a particular account or deployment has enabled them. Reply Kindly is a feedback product, not a booking engine, CRM, general survey builder or unrestricted AI data-search service. ## Product and pricing - [Product overview in Markdown](https://replykindly.com/nps-software.md): Bookings, appointments, audiences, workflow, AI report scope and limitations.
