Guide customers
Perform tasks
Connect with CRMs
Send messages
Handle bookings
Solve support tickets
Personalize responses
These bots can be deployed on websites, WhatsApp, apps, social media, customer service dashboards, and more.

1. User Sends a Message
Example: “What is my order status?”
2. NLP Processing
