# Chatbot

Software that simulates conversation with users via text or voice, often powered by NLP or LLMs.

## Definition

A chatbot is software that simulates conversation with users through text or voice. Early chatbots followed scripted decision trees. Modern chatbots use [natural language processing (NLP)](/glossary/natural-language-processing-nlp) and [large language models](/glossary/large-language-model-llm) to interpret open-ended questions and generate human-like replies.

Business chatbots typically sit on websites, in messaging apps, or inside [CRM](/glossary/crm) and support platforms. They handle tier-one questions (pricing, hours, order status), qualify leads, route complex issues to humans, and capture structured data from unstructured chat. The best ones are connected to real systems, not isolated FAQ readers.

LLM-powered chatbots need [AI guardrails](/glossary/ai-guardrails), grounding via [RAG](/glossary/rag-retrieval-augmented-generation), and clear escalation paths. Without those, they inherit model risks like [AI hallucination](/glossary/ai-hallucination) and [sycophancy](/glossary/sycophancy). McKinsey's 2023 research on customer experience noted that AI-assisted service can improve speed and consistency when human backup and knowledge bases are wired in from day one.

## Why It Matters for Middle Market Companies

For growth-stage operators, chatbots are often the first customer-facing AI touchpoint. Done well, they extend coverage without adding headcount. Done poorly, they frustrate buyers and damage trust faster than a static FAQ page.

The operational question is not "should we have a chatbot?" but "which conversations are safe to automate?" Order lookups and scheduling are low risk. Contract interpretation and custom pricing are not. Map journeys before you pick a platform.

[Conversational marketing](/glossary/conversational-marketing) uses chatbots earlier in the funnel to engage and qualify. [Conversational AI](/glossary/conversational-ai) is the broader capability layer. If you are evaluating agent-style support, compare scripted bots, retrieval-grounded bots, and full [AI agents](/glossary/ai-agent) using our guide on [choosing the best AI agent approach](/insights/best-ai-agent).
