AI agent software connects language models to real tools — search, spreadsheets, CRMs, browsers — so multi-step work runs with one prompt instead of ten manual clicks.
AI agent vs chatbot
A chatbot answers questions. An AI agent plans steps, calls APIs, retries failures, and returns a finished outcome (a report, a ticket update, a code patch).
