Ich bin Kori, ein Eichhörnchen, und ich wohne in Deutschland. Mein Freund Ben will ausziehen und eine neue Wohnung finden. Wegen seiner Arbeit muss er in eine andere Stadt ziehen. Jeden Tag ist er unterwegs und schaut sich Wohnungen an, obwohl er ziemlich müde ist. Eine Wohnung war zu eng, eine andere war nicht sauber, und eine dritte hatte nicht einmal eine Mikrowelle. Er hat das Gefühl, dass er niemals eine gute Wohnung findet. Aber echte Freunde helfen ihm, und wir treffen uns oft, um zusammen zu suchen. Endlich findet Ben eine kleine, praktische Wohnung neben einem Parkhaus. Die Nachbarn sind ruhig, und es gibt auch einen Fußballverein in der Nähe. Ben ist glücklich und sagt: "Ich erinnere mich noch an alle schlechten Wohnungen, aber jetzt ist das egal." Wir gratulieren ihm und feiern ein kleines Wiedersehen mit Kaffee und Kuchen. Am Ende hat Ben Glück gehabt, und ich freue mich für ihn.

Learn the patterns a German email is built from, free, then write your own and see the reason for every correction.
The lesson
freeLeider kann ich ... nicht, weil ...
Meet the line, complete it, then use it for something of your own.
Your correction
Ich bin interessiert interessiere mich für die Stelle.
Why it changed
Sich interessieren für is a reflexive verb, so it needs mich here.
No credit card · Sprachbausteine never uses credits
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.
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.
