Guten Tag, Hello, Salut, Ciao, Hallå, Hola, Здравейте, Ahoj, سلام
Our team of ten different nationalities warmly welcomes you.

Our Vision

Conversational AI and especially chatbots and voice assistants are more than a new tool. It is about a comprehensive transformation process that will permanently change the way in which we obtain information and manage knowledge.

While information and data are often still available in companies in so-called data silos and there is no automated access to this information, Onlim offers companies an automated solution to address these challenges with its Conversational AI platform and knowledge graph technology!

As a spin-off from the University of Innsbruck, Onlim’s AI-based chatbots and voice assistants are always automatically state-of-the-art.
