AI agents vs AI assistants: what is the difference?
Why "agent" and "assistant" mean different things for your business, and how to choose.
What an AI assistant does
An assistant responds. You type or say what you need, and it replies with an answer, a draft or an explanation. Nothing happens unless you take the next step yourself.
- Answering a question about a spreadsheet or an error
- Drafting an email you then edit and send
- Summing up a document you paste in
Assistants are low risk because you stay in every step. They are also limited by that: each job takes as long as you spend driving it. Mini NOVA is an assistant by design. It tells you the next step on your screen, and you make the click.
What an AI agent does
An agent is given a goal and works out the steps. It can search, read, write and use connected apps, checking its own progress until the job is done.
- Researching five competitors and putting their prices in a table
- Reading new enquiries and drafting a reply to each one
- Building a list of possible customers that match a description
The upside is time. You hand over a job, not a series of prompts. The risk is that an agent can act on something you didn't mean, like sending an email too early or using the wrong file.
Side by side
| AI assistant | AI agent | |
|---|---|---|
| Starts when | You ask a question | You give it a goal |
| Who does the steps | You | The agent |
| Uses other apps | Rarely | Often |
| Time saved | Minutes per question | Hours per job |
| Main risk | A wrong answer you can ignore | An action you didn't want |
| Best for | Quick help and one-off questions | Repeated, multi-step work |
Where AI employees fit
An AI employee is an agent with structure around it. It has a job title, skills and your instructions, it remembers your business, and it works alongside other AI employees. In JENA, anything that sends, posts or pays still waits for your approval, so you get an agent's speed with an assistant's control.

How to choose
- Choose an assistant when you need quick help with something in front of you, and the work is different every time.
- Choose an agent when the same kind of job comes back every week and you can describe what "done" looks like.
- Choose AI employees when you want agents, but with roles, a record of every action and approval before anything goes out.
Keeping agents safe
- Give each agent only the apps it needs for its job.
- Make anything that sends, posts or pays wait for a person.
- Keep a record of every action, so you can check what happened.
- Start with low-risk jobs, like research, before anything customer-facing.
