Hi Niklas,
if you're from Germany I wonder why you have not asked your question in the German forum? I mean, you seem to struggle a bit in English. No offense, but it felt just weird to me to link to German website when you're writing in English.
To answer your question: there is no release date yet, but SureAI aims to release Enderal this year. Right now there is an application for the closed alpha you could apply to, but good German is mandatory to participate as the alpha won't offer an English translation.
