## The situation

A bill of quantities has many items. One is easily missed. That gets expensive later.

## How it works

1. You paste the items.
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:** Review this bill of quantities. Is anything missing? Are there contradictions?

**What is in your text:**

> Project **Neubau Halle Lindenberg** for **Hof Lindenberg KG**:
> Item 3.2 foundation 38 m³, item 3.4 floor slab 640 m².

**What the cloud AI sees:**

> Project **Project Alpha** for **Client Alpha**:
> Item 3.2 foundation 38 m³, item 3.4 floor slab 640 m².
