Chatbot
A software interface that handles conversations — answering questions, routing requests, or guiding users through a process — using either predefined rules or AI language models. Modern AI-powered chatbots handle nuanced queries and maintain context across turns. Older rule-based chatbots follow fixed scripts and break outside their defined scope.
What is a Chatbot?
A chatbot is a software program designed to simulate conversation — receiving text (or voice) input from a user and generating a relevant response. Chatbots range from simple FAQ responders that match keywords to predefined answers, to sophisticated AI systems that understand natural language, maintain context across a conversation, and connect to back-end systems to take action.
The technology behind a chatbot determines what it can actually do. A rule-based chatbot follows a fixed script — useful for narrow, well-defined interactions like checking an order status. An AI-powered chatbot uses a language model to interpret intent and generate responses, making it capable of handling a wider range of inputs and more complex conversations.
Rule-Based vs. AI-Powered Chatbots
The gap between these two categories is larger than most people realize:
Rule-based chatbots: fast to build, predictable, brittle outside their defined scope. Ask anything off-script and they fail visibly.
AI-powered chatbots: handle varied inputs, maintain context, learn from interactions. But they require careful design to avoid confident wrong answers.
For business deployment, the choice depends on the task. Customer-facing FAQ handling may be adequately served by a well-designed rule-based system. Internal process support — helping a warehouse operator log an exception, or guiding a controller through a reconciliation — benefits from AI's ability to handle varied inputs naturally.
Chatbots in Operations
In operational settings, chatbots work best as the front end of a deeper automation system. A chatbot that accepts a supplier's delivery query and surfaces the correct PO status in seconds is valuable — not because it is smart, but because it routes the request correctly every time without a human in the loop. The chatbot handles the interface; the real work happens in the connected systems behind it.
