Frequently Asked Questions
Who is Careertrainer.ai for?
Careertrainer.ai is for everyone who wants to handle difficult conversations better: leaders, sales, customer support, and customer-facing professionals. Whether you're preparing for your first criticism conversation, training discovery calls, practicing support escalations, or want to become more confident in feedback conversations – you can practice every situation beforehand. HR teams and companies also use Careertrainer.ai to systematically develop leaders, sales, and support.
How do AI role-plays work?
You choose a scenario (e.g., criticism conversation with a defensive employee) and conduct a realistic conversation with an AI character. The AI reacts like a real person – with emotions, pauses, and spontaneous reactions. After the conversation, you receive detailed feedback: What went well, what you can improve, which formulations were helpful. You can repeat each conversation as often as you want until you feel confident.
Which conversations can I practice?
You can practice critical conversation situations from many areas: leadership (feedback, criticism, conflict conversations, annual reviews, salary negotiations, termination conversations), sales (discovery calls, objection handling, closing), and customer support (de-escalation, complaints). Each conversation type offers multiple scenarios with different character types – defensive, emotional, cooperative, or confrontational. This prepares you for different reactions.
What does Careertrainer.ai cost?
You can test Careertrainer.ai for free – without a credit card. After the trial period, there are flexible pricing models for individuals and teams. For companies, we offer team licenses with analytics and centralized management. Compared to external trainers or coaching sessions, you save significantly: A single coaching session often costs €200-500, while with Careertrainer.ai you can practice unlimited.
How does this differ from a real coach?
A coach is valuable for deep personal development. Careertrainer.ai complements this: You can practice specific conversations as often as you want – without appointment coordination, without paying each time. Many users use both: the coach for strategic topics, Careertrainer.ai for practical preparation for specific conversations. Unlike role-playing with colleagues, it's also completely confidential.
How realistic are the AI characters?
Our AI characters are based on psychological personality models and react like real people. They become emotional when you're insensitive. They block when you become too direct. They open up when you listen empathetically. Many users report that the conversations feel surprisingly real – including the stress that a real difficult conversation triggers. That's exactly what makes the training so effective.
Can I prepare for a specific conversation?
Yes, that's exactly what Careertrainer.ai is made for. Do you have a difficult conversation tomorrow? Choose a suitable scenario, practice different approaches, and find out which formulations work. The feedback shows you where you can improve. Many users use Careertrainer.ai the evening before an important conversation – 15 minutes of preparation can make the difference.
What about data privacy?
Your conversations are private. As a German company, we meet all GDPR requirements. Your data is hosted on servers in Germany and stored encrypted. We anonymize data so nothing is passed on to LLM providers that could be traced back to you. You can use Careertrainer.ai without anyone – including your employer – finding out which conversations you practice.
How often should I practice?
That depends on your goal. If you're preparing for a specific conversation, 2-3 runs the evening before are often enough. If you want to generally get better, we recommend 2-3 short sessions per month of 15 minutes each. The advantage over seminars: You don't forget anything because you practice regularly instead of attending a workshop once a year.
Does Careertrainer.ai also work for teams and companies?
Yes. In addition to individual use, we offer a team solution for companies. HR teams can invite leaders, sales, and customer support, track training progress in the dashboard, and create custom scenarios for company-specific challenges. This way, you develop people systematically and measure success. The team solution is suitable for onboarding, preparing for change processes, and scalable conversation training across all relevant areas.
Can I create my own scenarios?
In the team solution for companies, HR teams can create custom scenarios – e.g., for specific company challenges like restructurings, remote teams, or generational change. You can also upload your own leadership guidelines so the feedback takes them into account. For individual users, we offer a broad library of pre-made scenarios that cover most leadership situations.
How quickly can I start?
Immediately. After registration, you have direct access to all scenarios and can start your first conversation within 2 minutes. No appointment scheduling, no waiting time, no setup. If you want to use the team solution for your company, we support you with onboarding – even then you can start within 24 hours.
What distinguishes Careertrainer.ai from video courses or e-learning?
Video courses teach theory – you watch how someone else conducts a conversation. With Careertrainer.ai, you conduct the conversation yourself. You feel the stress when the AI character reacts emotionally. You notice which formulations work and which don't. This active practice anchors skills much more sustainably than passive watching. Studies show: After 30 days, 87% of seminar knowledge is forgotten – practical training remains.
Do you also offer support for companies?
Yes. For companies, we offer pilot projects over 4-8 weeks to test Careertrainer.ai in a realistic context. You get a personal contact person, support with custom scenarios, and detailed analytics reports. After the pilot phase, you can roll out the solution company-wide. This minimizes risk and you see concrete results before deciding.
How can Careertrainer.ai support sales teams with discovery calls and objection handling?
Careertrainer.ai enables sales teams to practice all critical sales conversations risk-free. You practice discovery calls with different customer types, train objection handling for price or time concerns, and perfect closing conversations. The AI characters react like real customers – skeptical, hesitant, or enthusiastic. After each conversation, you receive feedback on your argumentation, questioning technique, and conversation management. This significantly shortens the ramp-up time for new salespeople, and experienced sales professionals can continuously improve their closing rate.
Why should sales teams use AI role-plays for sales conversations?
Traditional sales training is expensive, time-consuming, and only happens sporadically. With Careertrainer.ai, you train whenever and as often as you want – without appointments, without costs per session. You can practice specific customer types and industry scenarios that occur in your daily work. The feedback is immediately available and shows you concretely which arguments work and where you can improve. Many sales teams use the platform to make new employees productive faster or to prepare for important customer conversations.
Which sales conversations can I practice with Careertrainer.ai?
You can practice all critical sales conversations: Discovery calls for needs analysis, presentation conversations, objection handling for price or time concerns, closing conversations, and follow-up conversations. Each scenario offers different customer types – from skeptical decision-makers to enthusiastic early adopters. This prepares you for different reactions and allows you to optimize your conversation management for various situations. The platform covers typical sales situations that occur in B2B and B2C environments.
Can I practice interview situations with Careertrainer.ai?
Yes, Careertrainer.ai supports HR and recruiting teams in training structured interviews and practicing fair candidate evaluation. You practice various interview situations – from initial conversations to salary negotiations. The AI characters represent different candidate profiles, so you learn to evaluate objectively and reduce bias. The training helps standardize interview quality across the entire company and handle difficult conversation situations such as rejections professionally. This feature is currently in development and will be available soon.
Does Careertrainer.ai also work for customer service and support teams?
Yes, Careertrainer.ai is ideal for customer service and support teams who need to master escalations, complaints, and emotional customer conversations. You practice de-escalation techniques in a safe environment without risking real customers. The AI characters react emotionally, frustrated, or angry – just like real customers in difficult situations. The feedback shows you which formulations have a calming effect and how you resolve conflicts professionally. This improves customer satisfaction and onboards new employees faster and more effectively. This feature is currently in development and will be available soon.
What distinguishes Careertrainer.ai from traditional sales training or role-plays with colleagues?
Traditional sales training is expensive, only happens sporadically, and doesn't provide individual, immediate feedback. Role-plays with colleagues are often uncomfortable and not confidential. Careertrainer.ai solves both problems: You train whenever you want, as often as you want, completely confidentially, and with immediate, detailed feedback. The AI characters react like real customers – with emotions, pauses, and unpredictable reactions. You can practice specific situations that occur in your daily work without coordinating appointments or burdening colleagues. This makes training more efficient, cost-effective, and sustainable.
Is AI training really as effective as training with real people?
AI training is not identical to training with real people, but it offers decisive advantages: You can practice as often as you want without risking real customers or employees. The AI characters are based on psychological personality models and react consistently like real people. Many users report that the conversations feel surprisingly realistic – including the stress and emotions. The decisive advantage: You can practice specific situations until you feel confident. For deep personal development, a human coach remains valuable – Careertrainer.ai complements this with practical, repeatable training.
