AI Character Library
Practice scenario
Practice a realistic conversation with our AI employee. Improve your conversation skills in a safe environment.
Realistic conversation partners for every training type.
Each character has its own story, motivations, and typical behaviors tailored to leadership, sales, service, or interview situations.
Characters for every training type
Our library includes characters for all training areas: skeptical buyers and price-sensitive decision-makers for sales training, upset customers and complex problem cases for customer service, various employee types for leadership conversations, and critical interviewers for interview training.
Sales: Skeptical buyers, budget decision-makers, technical evaluators
Customer Service: Upset customers, frequent reporters, complex issues
Leadership: Demotivated, confrontational, insecure employees
Interview: Critical HR Managers, Department Heads, C-Level Executives
Psychologically grounded personalities
Our characters are based on established personality models. An analytical buyer behaves differently than a relationship-oriented one—consistently throughout the entire conversation. This makes training realistic and the learning experience transferable to real situations.
16 MBTI personality types as a foundation
Typical communication styles by personality
Predictable responses to pressure, empathy, and argumentation.
Consistent behavior throughout the entire conversation.
Hidden motivations and objections
Real conversation partners have backgrounds that explain their behavior. The skeptical buyer may have been let down by the last provider. The frustrated customer has already made three unsuccessful calls. These layers unfold in the conversation—just like in reality.
Hidden objections that only arise during the conversation.
Backstories that explain skepticism or frustration
Real needs behind superficial arguments
Character development based on conversation style.

Practice with realistic personalities
Every employee is different – and reacts differently to feedback. Our characters are built on scientifically validated personality models and simulate realistic conversation dynamics: from the insecure junior employee to the critical senior developer.
Every character reacts differently
Frank Zimmermann
The tough negotiator
Procurement
Seasoned buyer who treats negotiations as sport. The decision is made – he just wants a lower price.

14 years in intensive care, on the verge of burnout. Can't say no and perceives exhaustion as failure.
Jürgen Haas

Marcus Berger
The fallen top performer
Private Banking

Contact UsFrequently Asked Questions
What character types are there for sales training?
For sales training, we offer various buyer and decision-maker types: the analytical buyer who seeks data and facts, the relationship-oriented decision-maker who wants to build trust, the price-focused budget holder, the technical evaluator with detailed questions, and the skeptical switch candidate who needs to be convinced by the competition. Each has typical objections that you can practice in the simulation.
Are there specific characters for customer service training?
Yes, we have customer types for various service situations: the frustrated customer after a wrong delivery, the frequent caller who contacts us for every little issue, the escalating customer who demands to speak to a supervisor, the factual problem-solver who wants a quick response, and the emotional customer who needs understanding before solutions can be offered. Each type requires different de-escalation and service strategies.
How realistically do the AI characters behave in conversation?
Our characters respond dynamically to your behavior – not according to a script. A skeptical buyer opens up when you conduct a good needs analysis. An upset customer calms down when you show genuine empathy. The reactions are consistent with their personality profiles: an analytical type won't suddenly become emotional, even with good guidance. Users regularly report that after a few conversations, they perceive the characters as real conversation partners.
Can I customize characters to fit our industry and target audience?
Yes, in the Enterprise package, you can create your own characters. Define the typical buyer for your industry with industry-specific objections. Create the recurring customer type that calls you. Model employee types that exist in your company. You can define personality profiles, set typical objections, and configure response patterns.
Are the characters portrayed in a stereotypical or clichéd manner?
No, we place great importance on avoiding clichés. Each character is a multidimensional personality. The older buyer is not automatically technology-averse, and the young customer is not automatically impatient. Instead, each character has a unique combination of personality type, experiences, and current situation. Our characters represent people, not categories.
