An algorithm that learns with you
Every answer helps Wuertschatz understand your strengths and your hesitations. Difficult words come back at the right time, while the ones you know make room for new challenges.
Going further
Wuertschatz does one thing and does it well: it makes words stick. For the theory, the dialogues and the teaching progression, the Aurelux app takes over, extended by Aurélie Wagener’s Luxembourgish courses. A wide vocabulary is also the best groundwork ahead of the citizenship language exam — see the Sproochentest page. And to put those words back into play differently, LuxQuiz offers crossword grids entirely in Luxembourgish.
