The situation

A customer writes a long message. You want to answer politely and clearly. And you have little time.

How it works

You paste the email.

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

Write a friendly reply to this email. Short and clear.

What is in your text

Hello Ms Petra Voss,
thank you for your message of 12 September 2026.
Your customer number is 48819.
We will get back to you by Friday.

What the cloud AI sees

Hello Customer Alpha,
thank you for your message of 12 September 2026.
Your customer number is CustomerNumber_1.
We will get back to you by Friday.

This example is made up.

What you get

You get a draft. You edit it and send it yourself.

Good to know

Read the draft before you send it. The Schleuse does not send emails.

Zone of this use case: Yellow

Only through the Schleuse. And only to targets you have approved.

Status of the Schleuse

Version 0.1 Alpha. So far tested only with made-up examples. Not reviewed by third parties. No legal advice.

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.
