What a WhatsApp Chatbot Is (and Why It Works in Campinas)
A Simple Definition
A chatbot is a virtual assistant that automatically answers messages on WhatsApp, using:
- Predefined rules (if the customer asks X, reply Y)
- Artificial Intelligence (understands context and replies naturally)
How It Works in Practice
Example - Dental Clinic:
Customer: "Hi, do you accept insurance?"
Bot: "Hi! Yes, we accept:
• Unimed
• Bradesco Dental
• SulAmérica
Which plan do you have?"
Customer: "Unimed"
Bot: "Perfect! To book your appointment, I need:
📝 Your full name:
📅 Best day (Mon-Fri):
⏰ Time of day (morning/afternoon):"
[Collects data + Books automatically + Notifies the receptionist]
The chatbot:
- Replies instantly
- Collects the information needed
- Books automatically
- Notifies the team when necessary
- Works 24 hours a day, 7 days a week
