AI Agent vs AI Assistant

TL;DR: An AI assistant responds when you ask (like a chat tool). An AI agent takes action toward a goal — it can use tools, make decisions, and complete multi-step tasks, sometimes on a schedule. If you need something done, you want an agent.

The key difference

  • Assistant — reactive. You ask, it answers. (Think chat.)
  • Agent — proactive. It plans, uses tools (email, calendar, code), and acts — with or without you watching.

How to tell which you need

  • Just want answers/drafts? An assistant is enough.
  • Want tasks completed (send the email, book the meeting, open the PR)? You need an agent.
