Lex chatbot beta to be launched this October

Soon, everyone in Denmark will be able to use Lex's Danish chatbot.

Over the past year, the chatbot has been developed as a research project through a collaboration between Lex and the Center for Humanities Computing at Aarhus University. Until now, it has only been available to a closed user panel. The project has now reached its next major milestone: we plan to launch a public version of the chatbot in October 2026.

Before then, however, we need to carry out extensive testing. Over the coming months, we will conduct A/B tests in which users are presented with two different responses from the chatbot and asked to evaluate which one works best. This will help us better understand what users prefer. Is it the content, the language, the tone, the structure, or the way sources are incorporated?

Technical testing can tell us a great deal, but it cannot replace human judgment. That's why we will be relying even more on our user panel in the coming months to test the chatbot, provide feedback, and identify areas where it can still be improved, helping us ensure it is ready for launch.

"We're incredibly excited to launch the chatbot in a public beta this October. It marks the culmination of months of hard work by both CHC and Lex, as well as feedback from thousands of test users. There are still many questions we'd like to answer before then, and we hope our users are ready for one more round of testing and feedback to help ensure the chatbot performs as it should and delivers the quality of answers our users deserve," says Simon Aagaard Enni.
