The situation

An invoice arrives. It is long. Nobody has time to check every line. It contains names, addresses and bank details.

How it works

You paste the invoice 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.

Example

Your question to the AI

Check this invoice. Do the totals add up? Is anything missing? Is a line item there twice?

What is in your text

Invoice from Müller Landtechnik GmbH to Mr Jonas Meier.
We debit DE89 3704 0044 0532 0130 00.
Total: 1,284.50 EUR.

What the cloud AI sees

Invoice from Company Alpha to Customer Alpha.
We debit IBAN_1.
Total: 1,284.50 EUR.

This example is made up.

What you get

You get a short list of things that stand out, such as duplicate items or calculation errors.

Good to know

AI does not always calculate correctly. Check important totals yourself.

Would you like to try this?

We are looking for pilot partners. We test the Schleuse with made-up or cleared examples first. Only then does real text go through.
