Check if a text came from KIplatz
Every answer from KIplatz carries an invisible label: written by an AI. It does not change a single word of the text.
Check a saved conversation
In the program, “Save conversation” creates a file. Open it, copy everything and paste it here. The page only sends the labeled answers for checking, and nothing is kept.
No name, no device, no question
Only what is needed
It says “generated by KIplatz”, the day, a checksum of the text and the signature of our server. Nothing more.
App, program, file
With every answer in the app and the program, in the saved conversation file and in the interface for other programs. If you copy an answer, the text stays exactly as it is.
No meddling with the words
We measured a watermark hidden in the choice of words and dropped it, because it changed the answers. The label sits next to the text, not inside it.
Required in the EU since August 2026
Since August 2026, the EU AI Act requires that text written by an AI can be recognized as such by machines (Art. 50(2) of the AI Act). The app and the program also show with every answer that you are talking to an AI.
Answers your PC gives directly on the device never pass through our server. They are labeled, but not signed.
Check with your own tool
You get the public key by sending an empty request to kiplatz.at/herkunft (POST, body {}). The signed line is “KIplatz-KI-Etikett/1|day|checksum”, and the response names the method.
The checksum is SHA-256 over the text after it has been brought into Unicode form NFC and every run of whitespace has been turned into a single space, with none left at the start or the end.
