AI helps. But not every text belongs in someone else’s cloud.
A contract, an error log, a customer list: it is quickly pasted into an AI chat. After that it sits with a third party. A ban often helps little. Then people use AI in secret.
Invoices and contracts
They contain names, addresses and account numbers.
Error logs and code
They contain passwords and server names.
Customer lists and meter data
They show who your customers are and what they need.

The Schleuse: use AI without giving away secrets
The Schleuse sits between your text and the cloud AI. It replaces secrets with stand-in words. It translates the answer back on your side.
You write as usual
You paste your text into your AI tool.
The Schleuse replaces secrets
Names, addresses, identifiers and credentials are replaced with stand-in words. This happens on your side, not in the cloud. Amounts and dates stay as they are.
The AI answers, the Schleuse translates back
The answer contains the stand-in words. On your side they turn back into the real names.

We make IT and AI usable in daily work. Not as a slide battle, but as skill and as running systems.
AI training
We explain AI so that it sticks. For teams and individuals.
- What AI can do today. And what it cannot.
- Asking good questions: ChatGPT, Claude and co.
- AI agents and automation in daily work
- In-house, in your team or as coaching
- Data protection: working safely with AI
IT and AI projects
From idea to running system. We plan, build and support.
- AI assistants for recurring tasks
- Data analysis and dashboards
- Web applications and interfaces
- Servers and operations
- Advice up front: is this possible at all?
AI strategy and feasibility test
Where is AI worth it for you? We show it on a small, real case before you invest.
- Taking stock
- Sorting ideas by benefit
- A small test with your data
- Decision paper for management
- Handover to your IT, if you want
How we work
No off-the-shelf standard. We start where things get stuck for you.
Hands-on
On real tasks from your business. What you learn, you use right away.
Tailored
Content and pace follow your team.
Clear
Plain language instead of buzzwords. So it sticks.
Reliable
Long-standing practice and a direct line. What we build, we also support.
Privacy-aware
AI yes, but with an eye on the GDPR and your data.
Measurable
We look at the benefit: time saved, better processes, real results.
Experience from real projects
For over 15 years we have built monitoring platforms and analysis for plant operators. Today that means digital twins, knowledge systems with AI and live dashboards.
- Since 2011: our own live monitoring platform and data loggers at large plants
- Since 2023: digital twins in a RAG knowledge system (stromfee.ai)
- Today: AI agents that take over recurring analysis
To be honest
The Schleuse is new. We would rather say what is missing than promise something.
- Version 0.1 Alpha. So far tested only with made-up examples.
- No detection is perfect. A small remainder can be left over. When in doubt, nothing is sent.
- So far measured with German texts only. There is no measurement for other languages yet.
- The Schleuse does not handle audio or video yet. Text, documents, images and scans, yes.
- No review by third parties. No legal review. Our evidence is technical, not a certificate.
- Legally this is pseudonymisation, not anonymisation. The key makes the way back possible and stays with you.
Frequently asked questions about the Schleuse
What is the Schleuse?
The Schleuse is a program between your text and a cloud AI. It replaces names, identifiers and credentials with stand-in words. It translates the AI's answer back on your side.
Who is the Schleuse for?
For everyone who works with texts full of names and numbers. For example office work, energy and farming, law firms, medical practices, municipalities, construction and software development.
Does the cloud AI see my real data?
It should only see stand-in words. But no detection is perfect. A small remainder can be left over. That is why the Schleuse checks before sending. When in doubt, nothing is sent.
What happens to the AI's answer?
The answer contains the stand-in words. On your side the key translates them back. A round-trip test checks that exactly the original comes out.
