For German learners and expats
German grammar checker: cases, endings and word order
To check German grammar, paste your text into Gramatik and tap Fix. The app corrects cases, articles, adjective endings, verb position, capitalisation and commas, and highlights every change in red and green, so you can see exactly where German tripped you up. You can keep the app in English while it corrects your German, on iPhone, Android or the web.

How to check German grammar
- 1
Paste your German text
An email to your landlord, a Goethe or telc writing task, a message – or a photo of it.
- 2
Tap Fix
Gramatik corrects it in German; you can also set German as the text language.
- 3
Study the highlights
The same fix showing up again and again (say, the dative after «mit») tells you what to practise.
The German mistakes learners make most
- Cases after prepositions: «mit mein Freund» → «mit meinem Freund» (mit + dative)
- Verb second: «Gestern ich bin …» → «Gestern bin ich …»
- Verb at the end of subordinate clauses: «weil ich wollte den Film sehen» → «weil ich den Film sehen wollte»
- Articles and adjective endings: «ein großen Haus» → «ein großes Haus»
- Capitalised nouns and the comma before dass, weil, wenn
More than a spell checker
Grammar mistakes in German are rarely typos – they're case and word-order errors that a dictionary-based checker misses. Gramatik reads the whole sentence. When you're stuck, translate a sentence from English into German first and then fix it, or look up a word in the built-in dictionary.
Frequently asked questions
Does it explain why something is wrong?
It highlights each change so you see the mistake next to the correction. It doesn't give a full grammar explanation for every rule; the list above covers the most common ones.
Is it free?
Yes: 5 free actions every day, in the app and on the web with a free account. Gramatik Pro makes them unlimited; cancel anytime.
Can it help with Goethe or telc writing tasks?
It corrects the language of your letter or essay. It doesn't grade it against the exam criteria, so use it to fix mistakes, not to predict a score.
Can I use it on my computer?
Yes, at app.gramatik.app – sign in with Google or email. Same account as the app.
