What Are AI-Powered Chatbots?

Definition

AI-powered chatbots are virtual assistants that use machine learning (ML), natural language processing (NLP), and deep learning to understand and respond to customer inquiries. These chatbots can simulate human-like conversations, enabling automated, context-aware customer support.

Types of AI Chatbots Used in Banking

1. Rule-Based Chatbots
   • Operate on predefined scripts and decision trees.
   • Suitable for basic queries such as FAQs, account balance inquiries, and branch locations.
2. AI-Powered Conversational Chatbots
   • Use NLP and machine learning to engage in dynamic, context-aware conversations.
   • Can assist in fraud detection, financial planning, and resolving complex banking issues.
3. Hybrid Chatbots (AI + Human Support)
   • Combine AI automation with live agent escalation when needed.
   • Useful for handling high-value transactions and sensitive customer issues.

Example:

• Bank of America’s Erica chatbot provides AI-powered financial insights, while human agents handle more complex queries.
