Executive Summary
MCH Group, one of Switzerland’s leading event organizers, needed a way to offer instant, accurate, and seamless support to both visitors and exhibitors across their many event websites, including Powertage—a key event in the Swiss electricity industry.
Frustrated by costly, low-accuracy solutions from other virtual agent providers, MCH Group partnered with mindit.io and Eclipsai to build a more powerful, reliable, and cost-effective assistant. Leveraging Retrieval-Augmented Generation (RAG), state-of-the-art cloud architecture, and smart compliance features, mindit.io delivered a scalable solution that exceeded client expectations in both performance and ROI.
Key Results
- Reached ~80% precision using automated evaluation frameworks
- 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
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.
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
Implementation Process
The delivery followed an iterative and metrics-driven process:
- Content Collection & Cleaning: Used advanced frameworks to scrape and sanitize web content
- Chunking & Retrieval Optimization: Continuously tested and tuned chunking strategies for long answers
- PII Detection Integration: Leveraged Microsoft Text Analytics for GDPR-compliant conversation logging
- Evaluation Pipeline: Built a precision framework scoring answers 1–5 against the client’s golden Q&A set
- Feedback & Monitoring Tools: Delivered a Power BI dashboard to track usage, thumbs-up/down feedback, and success rates
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
