When does an AI assistant become an AI agent?

When it takes autonomous actions across systems without requiring approval for each step. An assistant that drafts an email for your review is an assistant. One that drafts, sends, monitors for replies, and follows up—that's an agent. The distinction matters for trust, compliance, and ROI measurement.

AI Assistant

A broad category of AI-powered software that helps users complete tasks through natural language interaction. AI assistants range from simple Q&A tools (Siri, Alexa) to business productivity helpers (Microsoft Copilot, Notion AI) to autonomous AI agents. The term is less specific than 'agent'—an assistant implies helpfulness, while an agent implies autonomy. In practice, the line is blurring as assistants gain agentic capabilities.

Example

An executive AI assistant manages your calendar, drafts email responses, prepares meeting briefs, and books travel—bridging the gap between a passive chatbot and a fully autonomous agent by handling routine tasks while deferring complex decisions to you.
