Voice-first German tutor
Not a language app. A tutor that measures progress like a human one would.
GrammarFlow listens to you speak German, catches the grammar you keep getting wrong, and walks you through it — the way a real coach does. No streaks to game. No points to farm. Just the structures you've mastered, the ones you haven't, and what to work on tomorrow.

The difference
Most apps teach you vocabulary. A tutor teaches you your mistakes.
You don't need another flashcard deck. You need someone who notices that you keep mixing up der and den, knows why, and gives you the one drill that fixes it.
It listens to you speak
Voice-first conversation. Talk in German, the coach catches the grammar in real time and replies — no wall of red, no quizzes you forget by lunch.
It remembers your patterns
Cross-session mistake tracking. Your weak structures by name, with the exact sentences you slipped on and why. Surfaced again before you forget.
It measures what matters
23 grammar structures across CEFR A1–C1. The map fills in as you demonstrate each one in real conversation — not in a multiple-choice quiz.
It coaches, not gamifies
No streaks. No leaderboards. No notifications shaming you for missing a day. Just a quiet read on what you can already do, and what to look at tomorrow.
How it works
Four moves. That's the whole product.
Speak. Get caught. See why. Try again tomorrow with what you missed.
Step 01
Speak. The tutor catches you.
Real-time corrections in plain language. The coach quotes what you said, shows the fix, and explains the rule in one line — never a wall of red.
Direction, not location — Akkusativ.
Step 02
One mistake at a time.
The coach picks the structure you keep slipping on and stays with it. Today's focus shows you the exact pattern, the count, and the fix — in one sentence.

Step 03
Watch the map fill in.
23 grammar structures across A1–C1. Each cell brightens as you demonstrate it correctly across sessions — not in a single quiz, not by tapping multiple choice.

Step 04
End with a story, not silence.
Every session closes with three numbers and one sentence: what you did, what tightened, and what to focus on tomorrow.

WECHSEL.
Grammar isn't memorized. It's demonstrated.
The premise
What we're not
You've tried the apps. You know how it ends.
Streaks broken on day 31. A green owl in your notifications. 800 words you “learned” but can't actually use in a sentence.
Get started
Two minutes. Then you're speaking.
Pick your level on the next page, make an account, start with a three-sentence warm-up. No credit card. No streak countdown waiting to punish you.
What's next
German first. One language, done right.
We're starting with German because its grammar is precise enough to teach this way — cases, articles, word order, separable verbs. Other languages later, when we're sure we won't water down what works.
Stop drilling. Start speaking.
Two minutes to start. The first session is free, the second one is too, and so is the next month.
