The reality in many organizations

What happens when AI grows without a strategy.

Individual departments subscribe to their own tools, data flows into third-party clouds, pilot projects stall. Three concrete risks that almost every organization faces when an AI strategy is missing:

Tool sprawl instead of strategy

Every department subscribes to its own AI tools. Different interfaces, different legal frameworks – and nobody knows the total cost. IT loses oversight, finance loses cost control. Economies of scale remain out of reach.

Data leaks out – unnoticed

Employees enter sensitive business data into cloud AI services – without IT or data protection having any control over the data flow. Shadow AI is the compliance risk nobody talks about – until it is too late.

AI without integration is just a toy

ChatGPT knows the internet – but not your contracts, your CRM or your project documentation. Pilot projects emerge in isolated departments and quietly fade away. Without controlled access to your enterprise knowledge, the promised value never materialises.

Building your AI Strategy

How to take control of your AI landscape and unlock real ROI

The obvious approach

Subscribe to a single major AI provider – ChatGPT, Claude or Gemini for everyone. Quick to start, one contract. But:

  • Only one model family – other strengths remain untapped
  • Vendor lock-in: switching is costly or impossible
  • Pricing and features are dictated by the provider

The strategic approach

The Dornheim AI Platform unifies all leading AI models in one central, open-source-based platform:

  • The right model for every task – switchable at any time
  • Open source: full transparency, no lock-in
  • One access point, one policy, full cost control

The Dornheim AI Platform in practice

What your team can do with it from day one.

No theory – this is what working with the Dornheim AI Platform actually looks like.

All Models, One Interface

Gemini, Claude, Mistral & more —
centralized and unified.

Your employees work in a single, familiar interface — regardless of which model runs in the background. No switching between applications, no separate logins, no uncontrolled individual subscriptions.

  • Switch models via dropdown — mid-conversation
  • Custom presets and agents per user or team
  • New models available in minutes — no rollout effort

Your Documents, Your Answers

AI that knows your own data —
with source citations.

Upload contracts, manuals, reports, or specifications. The AI searches your knowledge base semantically and responds with concrete references to the original source.

  • PDF, Word, Excel, PowerPoint — processed directly in the chat
  • Answers with clickable source citations
  • OCR for scanned documents included
Dornheim AI Platform – RAG document analysis with source citations
The Second Opinion Principle

Two models respond.
A third one verifies.

Ask the same question to Claude and Gemini simultaneously. The answers appear side by side. If they diverge, that's a warning sign. A third model can serve as an auditor to analyze the differences — the most effective defense against AI hallucinations.

  • Parallel answers — discrepancies visible instantly
  • Auditor model flags contradictions automatically
  • Ideal for critical decisions, compliance, and healthcare
Dornheim AI Platform – Multi-model comparison with auditor function
Images, Video, Audio, 3D

Generative media —
directly from the chat.

Create images with Nano Banana, Flux, or Seedream. Generate videos with Veo, Sora, or Seedance. Produce professionally narrated text in many languages and voices — even your own. Even music can be composed and 3D models can be constructed. Everything directly in the same chat where you research and analyze — no switching to external tools.

  • All relevant multimedia AIs to choose from — depending on the use case
  • Create images, videos, audio, and 3D directly in the chat
  • Edit your own and generated media directly in the chat until they're perfect

Knowledge Management

Turn simple chats into
collective corporate knowledge.

AI conversations contain valuable insights. The platform turns your chat histories into a searchable archive for the entire team. Find research instantly, set bookmarks, and share successful solutions seamlessly with colleagues.

  • Find anything fast with real-time search and bookmarks
  • Collaboration: Flexibly edit and share chat histories across teams

Agents & Automation

AI agents that know
your processes.

Create specialized AI agents for recurring tasks: contract analysis, proposal review, meeting minutes, onboarding support. Each agent has its own instructions, its own data sources, and its own access permissions.

  • Domain-specific knowledge via RAG database
  • Connect external tools via MCP protocol
  • Role-based access: Who can use which agent?

Customization

The interface tailored to your needs:
Dark Mode, language & AI control.

The Dornheim AI Platform adapts to the way you work. Choose from numerous languages such as English or German and activate the eye-friendly Dark Mode. Control the AI's behavior precisely and decide for yourself whether it may search the internet.

  • Multilingual interface (English, German, and many more) and native Dark Mode
  • Detailed AI settings for answers precisely tailored to your tasks
  • Toggle live web search with one click — or disable it for strict internal use

tablet, and smartphone.

Use the platform flexibly at any workstation directly in your web browser — no installation required. On the go, simply install it as a Progressive Web App (PWA) on your phone or tablet. Your AI assistants are always at your fingertips.

  • No installation needed: Full access via any modern web browser
  • Optimized as a Progressive Web App (PWA) for iOS and Android

Tools & MCP

The path to real ROI:
Knowledge & tools connected.

Via the Model Context Protocol (MCP), you don't just connect tools like web crawlers — you securely link your corporate knowledge with AI. Tap into internal emails, chats, and cloud data sources — the decisive step toward real ROI. Tools can be managed centrally or on a per-user basis.

  • Securely connect web search, emails, clouds, databases etc.
  • Easy tool access in the prompt bar and sidebar
  • Set up MCP servers centrally or per user

Full Cost Control

Who consumes what? What's actually being used? — Everything in real time.

The Control Center shows your entire organization's AI usage at a glance. Set token budgets per user, team, or project. No surprises at the end of the month. Plus, you can see which AI models are actually being used and which are not.

  • Real-time dashboard: token usage, costs, model utilization
  • Budgets and limits per user or group
  • Export for internal billing and cost control

Data Sovereignty

Your Data. Your Rules.

With the Dornheim AI Platform, you can choose exactly the level of protection your organization requires.

Maximum Privacy for Your Data

Your prompts, documents, and chat histories are never used for model training — neither by Dornheim nor by the model providers. We exclusively use enterprise API access, with "Zero Data Retention" guarantees available on request. Additionally, chats without history storage are possible. Your data remains confidential.

You Choose the Location

External AI providers, a national or European managed cloud with ISO certification, or fully on-premise operation on your own servers. We advise you on which tier fits your IT strategy. You determine the data flow.

On Request, the AI Runs at Your Site

Modern AI models can now also be self-hosted. Only the server costs apply. We can handle this hosting for you or support you in setting it up on your own servers. Not a single byte leaves your premises.

Import and Export at Any Time

All chat histories, documents, and configurations belong to you. Import and export in open formats is possible at any time. No vendor lock-in.

Model Support

Your custom AI stack — curated from over 1,000 models.

There is no longer one single best AI model. Different tasks require different specialists – for text, image, video, audio, 3D and beyond. The market produces new ones every week. You don't have to keep up. We curate from over 1,000 available models the exact stack that fits your requirements – and update it as soon as something better comes along.

Frequently Asked Questions

A complete, legally compliant AI stack for enterprises, assembled from the most proven open-source systems for multi-AI chat, RAG vector database, user management, cloud and local AI models, enhanced by our own modules (Control Center, Document MCP Server, Multimedia MCP Server).

Two separate cost blocks:
1. Dornheim Services: One-time setup + optional monthly hosting/maintenance fee.
2. AI Consumption (Tokens): Usage-based — either via your own API keys (directly to OpenAI, Anthropic, etc.) or via our managed API package. Pay per token, no throttling, no hidden caps, monthly cost limits available.

No. Neither by Dornheim nor by the model providers. We exclusively use enterprise API access without training options, with "Zero Data Retention" guarantees available on request. With local AI models, not even a single byte leaves your network.

That's your decision:
Option 1: On your own servers (on-premise). Full control.
Option 2: In our German managed cloud (ISO-certified data centers).
Option 3: Your own API keys — we only route through.
In every case: German company, German law, German DPA.

Yes, absolutely. All open-source components are freely available. Our managed service is designed for organizations that want professional operations, GDPR compliance, and personal support without having to commit their own DevOps resources. The freedom to do it yourself is always yours.

Managed Cloud: 24–48 hours.
On-Premise: 1–5 days, depending on your IT infrastructure. We support your team with installation and configuration.

The platform is deliberately built to be modular. Every component can be replaced by an alternative without affecting the rest of the stack. This is one of the biggest advantages over monolithic solutions. Alternatively, we can often continue to maintain and update the open-source component ourselves, since the source code is naturally available.

In two ways:
1. RAG: The AI responds based on your own documents and cites its sources. This massively reduces fabricated answers.
2. Multi-Model Check: Have the same question answered by two different models. If the answers diverge, that's a warning sign. A third model can be deployed as an "auditor."
