About Lemonade
Lemonade is a private local AI desktop assistant for Windows and Linux, built and published by AIon X LLC at siplemona.de.
What Lemonade is
Lemonade is a finished desktop productivity application, not a hosted chat subscription or a model server. It reads files on your computer, looks at your screen when you explicitly ask, and creates real Word, Excel, PowerPoint and PDF documents. The language model runs on the computer already on your desk.
The product is designed around a clear boundary: local work stays local. There is no cloud inference service behind the assistant, no cloud document sync, and no behavioural analytics in the desktop app. Subscriptions use a separate Lemonade account; website analytics are optional. Network access is limited to documented functions such as downloading the runtime and models, checking for updates, licence activation, connected mail, approved web research, and configured external tools.
