You looked up that German word three times this week, and you still forgot it. KorrektWort saves the words you actually meet in lectures, chats and readings, explains them in your own language, and makes you review each one right before you would forget it.
Every German learner knows the feeling. You highlight new words in your textbook, you download yet another flashcard app, you promise yourself 20 minutes a day. Two weeks later the app is teaching you that "the turtle drinks milk," while the words from your actual seminar are still a mystery, and der, die, das feels like a coin flip.
Here is the thing: it is not your fault. Most apps drill a fixed list that someone else chose. But the German you need is the German in front of you, your lecture slides, your part-time job, the message a classmate just sent you.
KorrektWort turns it around. You bring the words, the AI does the heavy lifting, and spaced repetition makes them stick. It is made in Braunschweig, Germany by the team at KorrektCode.
📖 What Is KorrektWort?
The idea fits in three words: add a word, understand it, remember it. Type or paste any German word, and KorrektWort detects whether it is der, die or das, explains it in your own language with real examples, plays the pronunciation, then schedules it for review at exactly the right moment. Your words become your personal course.
🎯 Your Own Words, Not Textbook Lists
Save the words from your lectures, readings, series or chats. You learn vocabulary you will actually use this week, not "the turtle drinks milk."
🔤 der / die / das, Detected Automatically
The hardest part of German gets solved for you. Every noun comes with its correct article and plural, plus a game to drill the genders until they feel natural.
🌍 Explanations in Your Language
Grammar and meaning explained in 12+ languages, including English, Spanish, Turkish, Persian, Arabic, Polish, Ukrainian and Russian. No more looking up the word you used to explain the word.
🤖 Kori, Your Personal AI Tutor
Kori chats with you and writes short stories using the exact words you saved, so you meet them again in context. Practising speaking becomes low-pressure and, honestly, kind of addictive.
🔁 Spaced Repetition That Respects Your Time
Reviews appear right before you would forget a word, so nothing slips away and you never waste time on words you already know.
📝 Paste Homework, a Chat or Song Lyrics
Drop in any German text and get the grammar explained, sentence by sentence. It is like having a tutor on call at 11 pm the night before a deadline.
🧠 The Science: Why Learning This Way Actually Works
We did not invent these ideas. We built a tool around what language research has known for decades. Three findings shaped KorrektWort:
📉 You forget most new words within days, unless you review
Back in 1885, Hermann Ebbinghaus measured how fast we forget: about half of new material is gone within an hour, and roughly two thirds within a day. A modern replication (Murre & Dros, 2015) reproduced his curve almost exactly, 130 years later. Cramming the night before an exam simply does not last.
The KorrektWort solution: instead of cramming, KorrektWort shows each word again right before you would forget it. This "spaced repetition" delivers roughly 10 to 30% better long-term retention than massed study (Cepeda et al., a meta-analysis of 254 experiments), and it is one of the most reliable effects in all of psychology.
🎯 A surprisingly small set of words carries most of the language
Vocabulary research (Nation, 2006) found that the ~2,000 most frequent word families already cover about 80% of everyday text, and ~3,000 get you to roughly 95% of normal conversation. You do not need to know everything. You need the right words first.
The KorrektWort solution: you start on curated, high-frequency packs (925 exam words, plus Supermarkt, Beim Arzt, Bahn & Bus), then add the exact words from your own lectures and life, so every minute goes into vocabulary that actually pays off.
🧩 Words stick when they are personal and seen in context
We remember words far better when they connect to our own lives and turn up in real sentences, not as isolated flashcards. And actively recalling a word (retrieval practice) beats simply re-reading it.
The KorrektWort solution: every word is explained in your own language, then Kori brings it back in conversations and short stories built from your saved words, so you retrieve it in context again and again.
Put together: the right words, remembered at the right time, in a context you care about. That is the whole idea.
🎓 Built for the Way Students Actually Learn
You do not learn German in a vacuum. You learn it under deadlines, between classes and while juggling a job. KorrektWort fits into that:
- After a lecture: save five new words from the slides in 30 seconds. By exam week they are already in long-term memory.
- Exam prep (TestDaF, DSH, telc, Goethe): start from 925 curated exam words, then add your own weak spots.
- Homework help that teaches: paste the sentence you do not understand and see why it works, instead of copying an answer.
- Real life in Germany: ready-made packs for Supermarkt, Beim Arzt and Bahn & Bus, the vocabulary you need the moment you arrive.
- Speaking with confidence: rehearse with Kori before you have to say it out loud to a real person.
🌱 Watch Your Forest Grow (and Actually Stick With It)
Most language apps lose you by week three. KorrektWort is built so you keep coming back: every word you save and review grows Kori's forest, and you collect badges as you hit milestones. It sounds small, but watching your forest fill in is exactly the nudge that turns "I should study" into a daily habit.
Along the way you unlock badges, small trophies for streaks, reviews and words mastered. Silly, and motivating in exactly the right way:
🤔 Why Not Just Use a Normal Vocabulary App?
Standard apps are fine for your very first week. The difference shows up once you are past the basics and need your words, with grammar you can actually understand.
