| Purpose | Use cloud AI services without names, identifiers and credentials leaving your own equipment in plain text. |
| How it works | Detect locally, replace with stand-in words that keep the meaning, check, send to the cloud AI, translate the answer back on your side. |
| Detection | Fixed patterns with check digits, a name detector (Presidio, GLiNER) and a local language model as a second reader. Everything runs locally. |
| Key | Stays with the customer. In the relay server only in working memory and with an expiry time. |
| Zones | Green, yellow, red, blue. Rules may only get stricter. Red and blue never go to the cloud. |
| File formats | Text, PDF, Word, Excel, PowerPoint, OpenDocument, images and scans. No audio, no video. |
| Languages | So far measured with German only. |
| Version and status | 0.1 Alpha. So far tested only with made-up examples. |
| Review | No review by third parties. No legal review. |
| Legal classification | Pseudonymisation, not anonymisation. The evidence is technical and not a legal certificate. No legal advice. |
| Limits | No detection reaches one hundred percent. A small remainder is possible. When in doubt, nothing is sent. |
| Price | None yet. Pilot partners wanted. |
| Use cases | 30 described use cases in 7 fields: office, energy and farming, law and tax, medical care, municipalities, construction, software development. |
| Languages of this website | German and English. |

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