AI assistant or AI agent?

The short answer

An assistant helps, an agent does it itself.

An AI assistant works alongside a person: it summarises, looks things up and makes suggestions. An AI agent carries out a task itself: having a conversation, scheduling an appointment or transferring a customer.

Both have their place. The difference is who makes the decision, and therefore what you need to arrange up front.

The difference

Assistant and agent side by side.

AI assistant

Works for your employee

For example Microsoft 365 Copilot and the AI features in Zoom: summarising meetings, drafting emails and finding information. The employee decides.

AI agent

Works on its own

For example Teams Phone Agent as an AI receptionist, or voicebots and chatbots in the contact center. The agent handles the conversation and hands over to a person when needed.

Where agents already work

Four places where an agent does the work.

Reception

Answering the phone

Answering questions, transferring calls and taking messages, also outside office hours. For example with Teams Phone Agent.

Customer service

Handling repeat questions

Opening hours, order status or a password reset: the agent handles it and passes the difficult work to an employee.

Appointments

Scheduling and rescheduling

An agent books an appointment in your calendar or moves it, and confirms by email or SMS.

After the call

Following up and recording

After the call, an agent creates a ticket, updates the CRM and sends a summary.

Agreements up front

Five things to arrange before an agent goes live.

  • What may the agent do?Define which questions and actions the agent handles itself.
  • When does a person take over?With emotion, exceptions or when the customer asks for it.
  • Say it’s AIMandatory since August 2026 under the AI Act.
  • Which information does it use?An agent is only as good as the knowledge and systems it can access.
  • Measure the resultWas the customer really helped? Not just: how many calls were deflected.
What’s coming

Soon your customer’s AI may be calling.

Large tech companies are working on standards that let a consumer’s personal AI assistant contact a business on their behalf: moving an appointment, filing a complaint, cancelling a subscription.

That calls for new agreements in your customer contact. How do you recognise such an assistant, and what may it arrange?
