An AI customer service training simulator lets an agent rehearse a difficult call aloud, with an AI playing the customer, before the real customer is on the line. If you are evaluating one for yourself or for a team, you need a way to tell a useful simulator from a demo that looks good. This guide lists what to test, what the simulator cannot do and how to run a small pilot.
We make DIRI AI, so we use it as an example of answers, not as proof it fits your service desk. We do not name or compare other products.
What the simulator does
In DIRI AI, the agent speaks and the AI plays the customer. The customer can be calm, confused, impatient or angry, depending on the scenario. When the call ends, the agent gets a report with key moments from the conversation, stronger wording for those moments and one suggestion for the next attempt.
The point is repetition in safe conditions. A new agent does not have to learn how to handle a refund dispute on a live customer; they can handle it ten times in practice first. See customer service roleplay scenarios for situations worth rehearsing.
What to test, in order
Does it feel like a call?
Use a headset. Check how the customer reacts to pauses, interruptions and hesitation. If the exchange feels like reading prompts on a screen, agents will not take it seriously.
Can the customer be difficult in a realistic way?
Service calls are rarely about a clean question. They involve frustration, missing details and requests the agent cannot grant. Check that the simulated customer can push back, repeat themselves and change topic. Then check whether the agent can recover. For techniques, see how to handle an angry caller and de-escalation phrases.
Can you repeat the same scenario?
Improvement shows up on the second attempt. Look for scenarios an agent can run again immediately, so they can try a changed approach on the same situation.
Is the report usable by the agent alone?
An agent who gets a vague score will not know what to do. Look for a report that:
- quotes real moments from the call;
- offers stronger wording the agent can say next time;
- suggests one clear goal.
Open the sample call page to hear a call and see a report, and the report breakdown for what each section means.
Is it training or evaluation?
This is the question many buyers miss. A tool built for training gives each person their own report and uses it to practise. A tool used to rank people changes how honestly they practise, and in some settings falls under stricter rules. DIRI AI is intended for training, not for evaluating employees, and each participant sees their own report. If you plan any assessment use, take legal advice first. The QA scorecard template covers the separate job of reviewing real calls.
Does it work in your languages?
DIRI AI is live in Czech, English, Slovak, Polish, German, Spanish, Portuguese, Italian, French, Romanian and Hungarian. If your desk serves customers in one of those, test in that language and judge how natural the customer sounds.
What it cannot do
- It cannot replace product knowledge. An agent still needs to know your policies, systems and tone of voice.
- It cannot promise measurable change. We give no figures for call times or satisfaction. Practice helps agents prepare; what changes in your numbers depends on your team and your process. See call centre KPIs and training for how to think about this.
- It is not a substitute for coaching. A team leader still sees what a report cannot.
- It is a simulation. The AI customer can be wrong, so treat the feedback as a suggestion.
Data and privacy questions to ask any vendor
Ask where recordings and transcripts are stored, how long they are kept, who can see them and how deletion works. Read the privacy documents, and ask your data protection contact to review the data processing terms. Do not put real customer data into practice scenarios unless your company has approved it.
How to run a small pilot
- Pick two or three scenarios your agents find hardest, such as a complaint, a refund request or a call from someone who cannot be satisfied.
- Choose a few agents, including a sceptic and a new starter.
- Ask each to run each scenario twice, changing one thing on the second call.
- Gather answers: did it feel like a call, was the report useful, did the second attempt differ?
- Check the practical parts: invitations, language, who sees reports and what the plan costs afterwards.
Plans and how to start
Individuals can try one call on the Free plan: 3 voice calls a month of up to 5 minutes each, no card needed, with e-mail confirmation. A 7-day trial is available with a card. Team use is arranged through a team pilot rather than self-service. Check the pricing page for current terms.

Frequently asked questions
What is an AI customer service training simulator?
A tool where an agent speaks a call aloud and an AI plays the customer. In DIRI AI, a report follows each call.
Can it replace classroom training?
It does a different job: repeated spoken practice. A workshop is better for introducing methods. See AI sales practice vs classroom training.
Is it used to evaluate agents?
No. DIRI AI is intended for training, and the participant sees their own report.
How can a team start?
Through a team pilot. Individuals can try the Free plan first.
Which languages are live?
Czech, English, Slovak, Polish, German, Spanish, Portuguese, Italian, French, Romanian and Hungarian.
