AI Agent vs Chatbot: What's the Difference?
A chatbot answers questions in a single conversation and forgets you afterwards; an AI agent runs continuously, remembers you and takes real actions using tools. The line is whether it can do things, not just say things.
The words get used interchangeably, but they describe very different things. A chatbot is a conversation: you ask, it answers, the session ends. An agent is a worker: it remembers you, runs on its own schedule, and acts on the world through tools like your inbox and calendar.
The simplest test is whether it can take an action. A chatbot can tell you how to book a table. An agent books it.
How it works
A chatbot is essentially a language model behind a chat window. It responds to what you type, within a single session, and has no standing memory or ability to act. Close the tab and the context is gone. That makes it excellent for questions, drafting and brainstorming.
An agent wraps that same model in three extra layers. An agent loop so it can take a step, observe the result and continue. Persistent memory so it knows you tomorrow. And tools so it can actually do things: read email, create calendar events, send messages. Add a schedule and it acts without being prompted. That combination is what an agent that takes actions, not just answers really means.
OpenClaw, the open-source personal agent, is a clean example: LLM-agnostic, with memory files, a HEARTBEAT.md schedule and real channel integrations. Many products sit between the two poles. ChatGPT is mostly a chatbot, though its agent mode adds limited action-taking; see ChatGPT vs an AI agent.
Worked example
The same request to each:
| Capability | Chatbot | AI agent |
|---|---|---|
| Answer a question | Yes | Yes |
| Remember you next session | No | Yes |
| Act on a schedule | No | Yes |
| Send an email for you | No | Yes, with approval |
| Triage your inbox overnight | No | Yes |
| ”Watch this thread, remind me Friday” | Just explains how | Actually does it |
A chatbot ends the conversation when you stop typing. An agent keeps working between your messages, which is the whole reason to use one for ongoing tasks rather than one-off questions.
Try this in Liv
Liv is an agent, not a chatbot, so it remembers you and acts on your behalf:
- Start a free 14-day trial at https://app.liv4all.com. No credit card.
- Message Liv on Telegram, the default channel.
- Connect Gmail and Calendar via Google OAuth so it can take real actions, not just reply.
- Ask it to triage your inbox or send a daily briefing; outbound drafts wait for your approval.
Liv is in early access with batched onboarding, so you may join a short queue.
Common questions
Is ChatGPT a chatbot or an agent?
Primarily a chatbot, though its agent mode adds limited action-taking. See ChatGPT vs an AI agent.
Can a chatbot take actions like sending email?
Not on its own. That requires the tool access and loop that define an agent.
Do agents still answer questions like chatbots?
Yes. An agent does everything a chatbot does, plus memory, scheduling and actions.
Is an agent always autonomous?
Agents act on their own steps, but a good one pauses for approval on sensitive actions. See what an autonomous AI agent is.
Which do I need?
For one-off questions, a chatbot is fine. For ongoing work like inbox triage and scheduling, you want an agent.
Can I run my own agent?
Yes, OpenClaw is open-source and self-hostable, or use a managed service like Liv. See build vs buy an AI agent.
