Open WebUI with gpt-oss, Qwen and Ministral, without US clouds: your team drafts, summarises and queries its own documents. We set it up and run it.
Starting point
Your team wants AI. The open question is where confidential data goes and who is accountable.
Customer, client and staff data fall under the GDPR, professional secrets also under Section 203 StGB.
Many AI services pass requests on to GPT, Claude or Gemini. Their providers are subject to the CLOUD Act even with an EU data centre.
Without an approved solution, staff use private accounts, with no rules and no overview.
Since February 2025, Article 4 of the AI Act requires sufficient AI literacy among staff.
Walkthrough
The interface is Open WebUI, in your language and in the browser. Seven stops from everyday work.
More about Open WebUI01Compare models
Switch between gpt-oss-120b, Qwen and Ministral in the chat. Two models answer the same question side by side and you pick the better answer.
02Analyse documents
Upload PDF, Word, Excel or PowerPoint. The AI summarises, lists deadlines and amounts and translates on request.
03Create a knowledge base
Create a knowledge base, upload files, sync whole folders or add web pages and text. In the chat, a # brings in the collection and the answer cites its source.
04Web search
For publicly available information you switch on web search per chat and attach individual web pages directly. The answer cites its sources; only the search terms go to search engines, without reference to person or organisation.
05Scans, images, speech
Text recognition for scans and photos, image understanding, dictation by microphone and speech output. All with models operated in Germany by German providers.
06Assistants
Set the instructions, model and knowledge base once. The team picks the assistant like a model, templates live in the prompt library.

Reviews & projects
From local AI integration to architecture, data sovereignty and ongoing operations.
WZ-IT moved our studio infrastructure from decentralised individual devices to a central platform: every site is securely connected via VPN, new devices are onboarded automatically and an entire site is provisioned from a template, without manual steps on location. What impressed me most is the breadth and depth of their knowledge: Timo and Robin are not a typical IT provider who sets up a server and leaves. The two of them think their way into highly complex infrastructure and software topics, work through every requirement we put in front of them, and build networking, provisioning and operations so that everything fits together in the end. WZ-IT is an excellent partner for complex software, network and architecture projects.
