MCH Group + mindit.io: Boosting Engagement and Accuracy with a High-Performance Virtual Agent for Event Websites

About the Client

MCH Group organizes dozens of physical events throughout Switzerland each year, each with its own dedicated website and exhibitor ecosystem. From gardening expos to B2B energy forums like Powertage, their digital presence serves thousands of users looking for quick access to event details, exhibitor lists, and registration info.

They needed a virtual assistant that could handle a diverse range of user queries, reduce friction, and enhance the overall event experience—without compromising on accuracy, privacy, or cost.

/Key Results

Delivered GDPR-compliant conversation logging with real-time PII masking
Handled complex, multi-page content with advanced chunking and retrieval techniques
Enabled easy integration with a single code snippet and full UI customization
Achieved positive feedback from end-users, based on real-time analytics and surveys

/The Challenge

The client had previously experimented with virtual agents that were either prohibitively expensive (e.g., $0.99/session) or suffered from very low accuracy. Their primary challenges included:

Complex Content Structure: Information was scattered across multiple pages, especially exhibitor details
Data Privacy Needs: Needed strict GDPR compliance and automatic PII masking
Accuracy Targets: Had to meet an 80%+ precision rate based on a predefined set of golden Q&A pairs
Scalability: Solution needed to be customizable and deployable across multiple event sites

/Project Goals

mindit.io was tasked with creating a high-performance, cost-efficient virtual agent that:

Provides fast, accurate answers to common visitor and exhibitor questions
Achieves at least 80% precision, evaluated via an automated benchmark system
Complies with GDPR regulations and masks sensitive user data
Works with modular, customizable UI for seamless website integration
Avoids subscription-based pricing in favor of a lifetime license model

/mindit.io’s Solution

Together with Eclipsai, mindit.io implemented a virtual assistant built on the latest RAG architecture and powered by Azure Cognitive Services and Azure OpenAI.

The solution includes:

Web Scraping & Content Structuring: Cleans and extracts relevant data from complex websites
Smart Chunking & Retrieval Tuning: Ensures high accuracy even when answers span 10+ content chunks
PII Masking Using AI: Detects and hides personal data with Microsoft Text Analytics
Secure, Flexible Hosting: Can be deployed in the client’s Azure infrastructure or hosted externally
Automated Evaluation: Uses golden questions and AI scoring to monitor precision

/Results

The solution not only met but exceeded MCH Group’s performance and compliance expectations:

78–79% precision rate on benchmark evaluations
Significant time savings for visitors and exhibitors navigating complex sites
Full GDPR compliance, with secure infrastructure and real-time data masking
Positive user sentiment reflected in interaction feedback
Successful on-time delivery, with reusable architecture for future events
