**Zone**: Yellow · **Construction and trades**

## The situation

The company sends an invoice. The quantities are higher than in the measurement. You want to know where.

## How it works

1. You paste both texts.
2. **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.
3. **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:** Compare the invoice and the measurement. Where do the quantities differ?

**What is in your text:**

> Invoice from **Weser Bau GmbH**: floor slab 660 m².
> Measurement by **Site manager Kai Brandt**: floor slab 640 m².

**What the cloud AI sees:**

> Invoice from **Company Alpha**: floor slab 660 m².
> Measurement by **Site manager Alpha**: floor slab 640 m².
