E-commerce. Order status, delivery tracking and returns answered without a person, while confirmations and shipping updates go out on their own.
Restaurants and cafés. A reservation finished inside the chat, and the menu and opening hours answered the moment they're asked, including at 11pm.
Clinics, salons and healthcare. Booking, reminders and cancellations run themselves. Anything unusual goes straight to a person.
Real estate and automotive. Budget and preference collected in one form, so sales receives a qualified lead instead of a message that says "hi, interested."
Education and training. Programme and pricing questions answered, enrollment completed in the chat, term announcements sent to everyone at once.
Service and technical support. A fault logged, a photo requested and received, and the customer kept informed about where the job stands.
