About us

The tools we wanted for ourselves

We moved to Luxembourg and signed up for Sproochcours. Our vocabulary lists kept disappearing into the backs of notebooks, so we started OpenSprooch. We work on it in the evenings and on weekends, somewhere around the city.

Each tool solves a problem we ran into while learning Luxembourgish. We keep the projects small and put the code on GitHub. If something is missing, open an issue or work on it with us.

Nothing to sign up for

Open a tool and start. We don't ask for an email or password.
