Kori tells small stories about real life in Germany, from A1 to B2: the letter from the Amt, the doctor, the flat search, the late train. Tap any word for its meaning.

freeLeider kann ich ... nicht, weil ...

Kira findet die Serien schlecht, trotzdem sieht sie jeden Abend fern.
Kira thinks the shows are bad, yet she watches TV every evening.
Structure
verb-second word order
trotzdem counts as the first element, so the verb sieht must follow in second position, with the subject sie after it.
Paste a message, homework, or song lyrics. Kori explains every sentence in your language, draws its structure as colored building blocks, and picks out the words worth saving. Any grammar note can be kept as a lesson to review later.
Or type just the expression that stopped you. Kori names what it is, an idiom, a proverb or a fixed phrase, says what a German actually means by it, and keeps the word for word picture separate, so ein durchwachsenes Ergebnis comes back as a result that was partly good and partly disappointing, not as something grown through with something.

Kori writes short German stories at your level, built from the words you saved. Tap anything you don't recognize: the meaning appears instantly in your language, free, and one more tap adds it to your stash.

Wrong answers come straight back until they sit
German's hardest everyday problem, turned into a quick-fire game over your own nouns. No AI, no credits, no excuses: fifteen taps with your morning coffee and the articles start sitting.
A young oak stands

No abstract points. Every word you collect grows Kori's forest: a sprout becomes an oak, an oak becomes a grove, and one day the whole squirrel village stands. Your A1 to C2 journey and achievements come along for the ride.
Kori is building the biggest German word stash in the forest, and yours is part of it. Kori chats with you, writes your stories, celebrates your progress, and reminds you gently when words are waiting. Never pushy, never guilt-tripping, always on your side.
