Kartoffel lets you work and study in Germany, explore Germany, and speak, read, write and understand German.
Your AI German teacher learns how you learn, explains what you don't understand, remembers your mistakes and speaks with you whenever you want.
Free to start, no sign-up to try. Never learned German? Lektion 1 starts with the ABC.
Guten Morgen! Was darf ich Ihnen bringen?
First you notice. Then you understand.
No rule tables up front. Every lesson starts with something to spot — the rule arrives the moment you're curious about it.
- 01Discover
You notice the pattern yourself before any rule appears.
- 02Understand
Colour, shape and motion show what each word is doing.
- 03Use it
Minutes later you say it out loud in a real situation.
Can you spot the difference?
Tap the word that changed.
Not a chatbot. A café in Kreuzberg.
Talk out loud with characters who have a job to do. They slow down when you struggle, push you when you're flying, and quietly write down every mistake for later.
- Roleplays: café, hotel, doctor, job interview, Bürgeramt…
- You choose how it corrects you, from relaxed to teacher
- „Help me“ gives hints in four steps — never the answer first
