If you are buying practice for yourself, the best app is the one you will open every day, even on a bad day. You have no administrator, no onboarding programme and nobody to chase you. So the checks are different from those a team would make: speed to start, how it feels to speak to it, how useful the feedback is on your own, and what it costs when you stop using it.
We make DIRI AI and use it as the worked example. We do not compare it with named competitors; the checklist works for any app.
Who this is for
This page is for you if you are:
- a freelancer or sole trader who sells by phone;
- a salesperson who wants extra practice beyond what the company provides;
- someone starting in a sales or appointment-setting role;
- a person who dislikes phoning and wants a low-pressure place to get used to it.
If you are choosing for a team, see how to choose AI sales role-play software instead.
The checks that matter for one person
1. Can you start in a minute?
An app that needs a long setup will not survive a busy week. Look for a short path from opening the app to speaking. Test it on a day you do not feel like practising.
2. Do you speak, or do you type?
If you sell on the phone, spoken practice is the closer match. Typing trains your writing; speaking trains your voice, your pace and your ability to think while talking. Use a headset and see whether the exchange feels like a call.
3. Does the customer answer back?
You need resistance. In DIRI AI the AI plays the customer, so it can push back on price, brush you off or interrupt, depending on the scenario. A tool where nothing resists you is a mirror, not practice.
4. Is the feedback something you can use alone?
With no manager beside you, the report has to do the coaching. Look for these features:
- it points at specific moments in your call;
- it gives stronger wording for those moments, so you can say the better line next time (the DIRI AI report does this);
- it suggests one thing to try next;
- it is written in a language you read comfortably.
You can see a real example on the sample call page and read what each part means in the report breakdown.
5. Is it in your language?
Practising in a language you do not sell in is of limited use. DIRI AI is live in Czech, English, Slovak, Polish, German, Spanish, Portuguese, Italian, French, Romanian and Hungarian. Test a call in your own market language before you decide.
6. What does it cost, and how do you stop?
Ask about the free option, the length of any trial, whether a card is needed and how you cancel. For DIRI AI:
- Free plan: 3 voice calls a month of up to 5 minutes each, no card needed (e-mail confirmation is required).
- 7-day trial: available with a card.
Check the pricing page for current terms. For any app, find the cancellation route before you enter payment details.
What a sensible solo routine looks like
A short daily habit beats a long occasional session. One way to use a Free plan call:
- Decide the single skill for the day, such as your opener or one objection.
- Make the call, up to five minutes.
- Read the report and choose one change.
- Say the new wording aloud a few times away from the app.
- Run the call again next time with that change.
If five minutes feels short, that is useful. It makes you pick a narrow target, which is how most people improve. The 10-minute practice guide and the solo cold-calling routine have more structure.
What to be careful with
- Scores with no explanation. A number without examples tells you nothing to do.
- Big promises. No app can promise that you will sell more. Practice helps you prepare.
- Real customer data. Do not put confidential customer details into practice scenarios unless your employer has approved the tool.
- Using it as a verdict. A bad practice call is not a measure of you. It is where you are allowed to be bad.
When an app may not be what you need
An app is one option among several. A colleague gives you a real person's reactions, and a human coach sees what a report cannot; see AI role-play vs practising with a colleague. If you only need to prepare words for a call, a general chat assistant can help; see ChatGPT vs a voice AI trainer.
If your employer wants it for the team
An individual account and a team arrangement are different things. If your company wants to use DIRI AI for several people, that goes through a team pilot, with its own terms. Ask your manager before you use a personal account for anything involving company information.

Frequently asked questions
What should a sales call practice app include?
Spoken practice, a customer who responds to what you say, feedback that points at moments in your call, and clear costs. Beyond that, decide by your own goal.
Can I use it for free?
DIRI AI has a Free plan: 3 voice calls a month of up to 5 minutes each, no card needed. There is also a 7-day trial for paid plans: a card is required, and it becomes available after your third Free call for accounts signed up in English or Czech. Check the pricing page for current terms. See the pricing page.
Do I need a team to use it?
No. An individual can use it alone. Team use goes through a team pilot.
Does the app tell me what to say?
The report suggests stronger wording for key moments. Treat it as a suggestion, not a script.
Which languages work?
Czech, English, Slovak, Polish, German, Spanish, Portuguese, Italian, French, Romanian and Hungarian are live.
DIRI AI trains communication and provides a report after each practice call; the participant sees their own report. It is intended for training, not for evaluating employees.
The Free plan includes 3 voice calls a month of up to 5 minutes each; e-mail confirmation is required. Check current terms before you start.
