Before deployment, the chatbot undergoes extensive testing to identify and fix issues related to response accuracy, security, performance, and user experience. This ensures reliable and consistent interactions.

6. Deployment and Continuous Improvement

After successful testing, the chatbot is deployed across websites, mobile applications, messaging platforms, or other communication channels. Continuous monitoring, performance analysis, and regular updates help improve accuracy, introduce new features, and maintain long-term effectiveness.
