Viessmann

Viessmann helps households and businesses transition to efficient and eco-friendly technologies – heat pumps, solar systems, ventilation... The website contains extensive documentation, parameters, certifications, and product differences. However, the average visitor often doesn't know where to start – and needs an answer right away.

Our internal documentation comprises more than 5,000 technical documents spanning dozens of pages each. Each contains detailed information about product lines, manuals, installation, and service. It was difficult for end users and partners to quickly orient themselves in the data. We also had to account for our internal guidelines, GDPR rules, and the need for precise referral to specific service or sales channels.

Using Kanbu.ai, we created an expert AI assistant capable of working with a complex document structure including images and metadata. The agent supports shared datasets, works with contextual cache, and can manage access by user type. If an answer is not known, it redirects the user to a specific contact form. We implemented a mechanism for removing indexes after document deletion and added legal disclaimers for the partner portal.
