Drei Forscher.
Eine gemeinsame Verantwortung: sichere KI.

Gretchen AI wurde von drei Forschern gegründet – Dr.-Ing. Tim Polzehl, Arnab Das und Daniel Röder.

Aus der Forschung heraus entstand eine klare Erkenntnis: Leistungsfähige KI braucht Verantwortung.

Gretchen AI schließt diese Lücke – mit Technologien, die erklärbar, überprüfbar und dem Menschen verpflichtet sind.
