## The situation

An authority sends a letter. The language is hard. You do not know: What should I do? By when?

## How it works

1. You paste the text of the letter.
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:** Explain this letter in plain words. What do I have to do, and by when?

**What is in your text:**

> Dear **Mr Meier**,
> regarding your file number **AZ 2026/4711-B**:
> Please submit the documents by 30 October 2026.

**What the cloud AI sees:**

> Dear **Customer Alpha**,
> regarding your file number **FileNumber_1**:
> Please submit the documents by 30 October 2026.
