XARA – XR Dialog Trainer

XARA is a GPT-4 (OpenAI) based conversation simulator that realistically reproduces virtual dialogues and can be flexibly adapted to various scenarios. This AI-driven platform offers a location-independent, cost-effective, and scalable method for interactively training a wide range of conversational situations—from recruitment and conflict management to customer interactions.

With the Swiss German mode, conversations can now also be conducted in the local dialect, providing authentic added value, especially for communication within Swiss companies or institutions.

The web platform allows the creation of customized dialog scenarios that stand out due to their dynamic and context-sensitive responses. Available both as a web application and in VR/AR, XARA provides an immersive training experience tailored to the specific needs of diverse target groups.

Features

• AI-based Language Processing (GPT-4)
  Delivers context-specific and precise answers — easily adaptable to the flow of conversation.

• Custom Dialogues
  Simple scenario creation via an intuitive web platform — requires no in-depth technical knowledge. Now also available for authentic scenarios in Swiss German.

• Realistic Simulation
  Credible conversation flows thanks to AI that reacts dynamically to user input.

• Cross-Platform Availability
  Accessible through a web browser, and also usable in Virtual Reality (VR) and Augmented Reality (AR).

• Logging & Feedback
  Conversation transcripts are documented. The AI can then be used for targeted feedback discussions to identify strengths, weaknesses, and areas for improvement.

Typical Use Case

• Recruitment
  Realistic interviews help structure the hiring process.

• Conflict Conversation
  Practice handling critical situations to respond confidently in real scenarios.

• Termination
  Hone professional communication skills for sensitive employee discussions.

• Open Question Rounds
  Spontaneous dialogues foster creative thinking and enhance conversational competence.

Technical Perspective

• GPT-4 Integration
  Highly advanced AI that analyzes inputs in real time and responds with appropriate, context-sensitive answers.

• Secure Data Management
  Conversation transcripts can be stored locally or in the cloud — flexible and compliant with data protection standards.

• Modular System
  With planned RAG support (Retrieval-Augmented Generation), external data sources (e.g., websites, documents) can be integrated to create even more authentic scenarios.

• Customizable Model Setup
  Choose between various AI engines (e.g., GPT-3.5, GPT-4, Mistral) depending on the application.

Future Development

• Enhanced Speech Recognition & Multilingual Voices
  Real-time processing of voice recordings, including additional dialects and languages, to create an even more authentic training experience—from Swiss German to international languages.

• RAG System for Data Integration
  Integration of information from websites, documents, and other sources through Retrieval-Augmented Generation (RAG) to enable even more customized and realistic dialogue scenarios.

• Custom Models
  Choice between various AI engines such as GPT-3.5, GPT-4, or Mistral to optimize conversation simulation for specific requirements.

• New Web and Mobile App
  A planned user-friendly web and mobile application to make access and training even more convenient and flexible.

• Individual Licenses
  Tailored user quotas and service levels for different company sizes and requirements.

• More Avatars
  An expanded selection of avatars and characters to support a broader range of conversation scenarios and roles.

Customer Feedback

"XARA was born out of the desire to practise staff appraisals: A ready-to-use product that realistically simulates interviews in virtual environments. Using the XARA web platform, we were able to create customised interview scenarios on the topics of recruitment, conflict and dismissal. The dialogues move within the framework of the scenarios - but adapt dynamically to the course of the conversation. With XARA, we are creating a further training programme at the University of St. Gallen. At the same time, we are conducting research as part of a study on learning communication skills with XARA in virtual environments."
