Our approach
Sovereign AI is a lifecycle, not a device purchase: advice, build and operations come from one team.
Workshop, sizing, data classification and §203 contract framework. We understand your stack, professional software and compliance requirements before we recommend.
On-premise build on your hardware, RAG on your documents with access control, integration into your professional software. Plus the DPA and, on request, a written secrecy obligation under Section 203 StGB.
Updates, monitoring, model upgrades and RAG upkeep in ongoing operation. For the AI Cube, AI Cube Care runs with the device for the first twelve months and is cancellable monthly after that; handover to your team and knowledge transfer included.
Legal framework
We configure and operate the local AI platform for the agreed GDPR and Section 203 scope, as an AI Cube or on your own infrastructure. This includes controlled data paths, limited permissions, documented maintenance, the appropriate DPA and, on request, written secrecy obligations for the people involved. Legal evaluation of the specific use remains with the controller and its advisers.
What we deliver for it: AVV (data-protection layer) · Written secrecy obligation (secrecy and instruction on criminal consequences) · Maintenance and access concept (necessary rights, logging and controlled paths).
This content is general information and not legal or tax advice. The specific implementation under §203 must be reviewed professionally on a case-by-case basis.
AI Cube
AI Cube brings a familiar AI chat, local models and dedicated knowledge areas into the practice. Staff can use approved templates and documents as knowledge. PMS connections and automated data flows are assessed and implemented separately.
Beyond that

The data processing agreement under Art. 28 GDPR comes with the order; for confidentiality professionals the written secrecy obligation is available on request under Section 203 (4) of the German Criminal Code, including instruction on the criminal consequences; on request remote access stays switched off by default.

Reviews & projects
From a knowledge base with an AI assistant and local AI integration to data sovereignty and ongoing operations.
AI Platform
We were looking for a secure yet easy-to-use alternative to the large American providers and came across WZ-IT. WZ-IT advised us on choosing the right models and implemented the integration for us. Beforehand, we were able to try everything out calmly on a test instance. Today WZ-IT runs Open WebUI for us on our own domain, with a convenient Microsoft login and open-source models hosted by a German provider. Our team can now work productively with AI without resorting to external tools or shadow AI. Working together is straightforward, and questions are answered quickly and clearly. With WZ-IT we also have a partner at our side for further AI projects. (translated)
Carl-Frederic KornHead of E-Commerce & Online Marketing, Krüger Dirndl GmbHKnowledge Management & AI
The knowledge from many years in the solar industry lived in the head of our former managing director, and it still lives in the heads of our employees today. We wanted to secure it, not as a folder full of notes, but in a way that lets us ask questions in daily work and get reliable answers. WZ-IT advised us from the start and weighed different approaches and knowledge management systems against each other with us before we decided. What was built is a custom knowledge base with an AI assistant that brings together conversations, notes, documentation and manuals: from the platform through onboarding our team to support in operation. Conversations are transcribed and facts are extracted; we review and correct everything ourselves before it is stored, because we do not want to trust an AI blindly. The system runs in our own environment, and the data stays with us. What surprised us was how efficient it was: WZ-IT used existing open-source software and extended it specifically for our requirements, instead of selling an expensive custom build from scratch, as is often usual with IT service providers. Timo and Robin understood our actual problem, preserving knowledge during the generational handover, and implemented it step by step: from the proof of concept through setup and validation with our own data to productive operation, explaining everything clearly along the way. Next, we want to extend this to the knowledge of our employees, so that this does not depend on individual people either.
