Learn German by talking to historical figures
Last updated 2 June 2026
Talking to Mozart or Goethe in German is far more memorable than another drill, and it gives a conversation a reason to keep going. KLUG includes character roleplays with on-device AI, so you can hold a playful German conversation with a famous figure, privately, on your iPhone or iPad.
Why characters make practice stick
A conversation with a personality is easier to stay in than an exercise. Asking Mozart about music, or Goethe about an idea, in simple German, gives you a thread to follow and a reason to reach for new words. It turns speaking practice into something you want to do, which is what keeps a daily habit alive.
Playful, but real practice
KLUG's characters include figures like Mozart and Goethe, alongside everyday scenarios and debate topics. The AI runs on the device, so it is private and works without sending your words anywhere. KLUG teaches in German, runs on iPhone and iPad, and is free to start, with no third-party ads or tracking. Free users see KLUG's own occasional prompt to upgrade.
