Every German sentence can become your personal lesson

German arrives at you all day long. A message from your landlord, a sign in the S-Bahn, an email from the Krankenkasse, a line in a song. Most learners do the same thing with all of it: paste it into a translator, read the English, move on.

You understood that one sentence. You learned almost nothing you can use on the next one.

Translation answers the wrong question

Take a sentence you might genuinely receive:

A translator gives you "I have to pay the invoice by Friday", and it is correct. But look at what it quietly hides. In German the second verb went to the very end of the sentence, far away from muss. In English the two verbs stay glued together: have to pay. That gap is one of the first things that makes German feel unreadable to English speakers, and the translation says nothing about it.

So the next time you meet Ich möchte den Vertrag morgen kündigen, you are back where you started, translating again. The sentence taught you nothing transferable, because nobody told you it was an example of a rule.

That is the difference between understanding a sentence and learning from it. A tutor would have pointed at the pattern. A translator never will.

Explain: what you get instead

Paste any German text into KorrektWort's Explain and it comes back broken into sentences. For each one you get:

• The meaning in your own language, natural rather than word by word, so you read it the way a person would say it.
• The English version too, if English is not your first language. German is a Germanic language, so English is often the closer comparison, and seeing both is frequently what makes a structure click.
• One grammar note about the single most learnable thing in that sentence.
• The vocabulary worth keeping, each word with its dictionary form, CEFR level and meaning, savable in one tap.

You can also hide the meaning and try the German first, which turns a passage you were going to read anyway into actual reading practice.

Grammar you can see, not just read

The grammar note is not a definition copied from a reference book. It names the rule, shows this exact sentence obeying it, and where a structure has a confusable sibling it contrasts them, because obwohl against trotzdem, or weil against deshalb, is where most learners actually lose points.

And when the rule is about where things sit in the sentence, prose is a poor way to explain it. So Explain also lays the sentence out in labelled blocks:

Now the rule is visible. muss takes second position, bezahlen is thrown to the end, and everything else lives inside the bracket between them. Once you have seen that shape a few times in sentences from your own life, you stop decoding German word by word and start recognising the frame it is built on.

Keep the ones worth keeping

A good explanation you read once and never see again is only slightly better than a translation. So every grammar note has a bookmark on it. Tap it and the note joins your Lessons, with its topic, its category, and the German sentence it came from, so weeks later you still see why that note exists.

Lessons is the same place your practice-chat corrections land. When the AI tutor corrects something you wrote, Kori can turn those corrections into short lessons too. Over time you end up with a filterable list, word order here, articles there, separable verbs somewhere else, built entirely out of the mistakes you actually make and the sentences you actually met.

Your own knowledge library, not a textbook

This is the part that compounds. A textbook gives every learner the same chapter on the verb bracket. What KorrektWort accumulates is different, because everything in it came from your life:

• Your words, captured from real messages and signs, each with its der/die/das, plural, examples and pronunciation.
• Your grammar notes, kept from the sentences that confused you, filed by topic.
• Your analyses, saved so you can reopen a text you worked through last month and read it again for free.
• Your review schedule, which brings the words back just before you would forget them.
• Your stories and conversations, generated from the words you saved, which is how a word you recognise becomes a word you can use.

A textbook is finished when you close it. A library like this gets more useful the longer you learn, because it is a record of exactly where your German is thin.

Try it with something real

Do not test it with a textbook sentence. Take the last German message you did not fully understand, the one you screenshotted and meant to come back to, and paste that. You will get it sentence by sentence in your language, the rule each sentence is built on, and a short list of words worth keeping, with a bookmark next to anything you want to revisit.

KorrektWort is free to start, with 20 credits included and no card required. An analysis costs 2 credits, and rereading a saved one is free forever.
