Need a reliable german grammar checker to proofread essays, emails, or business documents?

Introduction

The german grammar checker from Rephrasely is designed for learners, professionals, and content creators who want fast, accurate corrections. It handles German-specific issues such as noun capitalization, case endings, separable verbs, and comma placement in subordinate clauses.

Try it online at Rephrasely and combine corrections with the AI writer, plagiarism checker, or AI detector to finalize content confidently.

How It Works (step-by-step for German)

  1. Paste or type your text: Enter your German text into the editor. You can paste whole documents or short sentences.
  2. Select language and dialect: Choose German (Deutsch). If needed, specify Austrian or Swiss conventions to tailor corrections.
  3. Choose correction level: Pick from basic (spelling and punctuation), grammar-focused, or advanced style and tone suggestions.
  4. Review suggestions: The tool highlights issues—capitalized nouns, case errors, verb position, separable verbs, missing commas—and explains why each change is recommended.
  5. Apply or customize: Accept all changes or pick specific suggestions. You can also rephrase segments with the built-in paraphraser or ask the AI writer for alternative formulations.
  6. Verify and export: Run a plagiarism check via the plagiarism checker if needed, then download or copy the corrected text.

Examples — Before & After (German)

Before After
ich habe gestern die filme gesehen und es war sehr gut. Ich habe gestern den Film gesehen, und er war sehr gut.
Wenn ich zeit habe, ich werde dich anrufen. Wenn ich Zeit habe, werde ich dich anrufen.
Er hat die türen geöffnet aber niemand war drinnen. Er hat die Türen geöffnet, aber niemand war drinnen.

Notes: The checker fixes capitalization of nouns (Zeit, Türen), moves the verb in subordinate clauses, and suggests punctuation improvements (commas before conjunctions in complex clauses where appropriate).

Supported Features (for German)

  • Grammar corrections: case endings (Nominativ, Genitiv, Dativ, Akkusativ), verb conjugation, word order.
  • Capitalization: automatic detection and correction of all German nouns and sentence starts.
  • Comma rules: suggestions for mandatory commas in subordinate clauses and optional commas in lists.
  • Separable verbs: correct placement and spelling of separable prefix verbs (e.g., "anrufen" → "ruft ... an").
  • Pronoun and formality checks: guidance on Sie vs. du, capitalization of formal address, and consistent register.
  • Style and tone: suggestions for formal, neutral, or casual registers suitable for emails, essays, or marketing copy.
  • Vocabulary suggestions: synonyms and collocation improvements tailored to German usage.
  • Dialect support: Austrian and Swiss variants for spelling and vocabulary differences.
  • Integrated tools: paraphraser, plagiarism checker, AI detector, and AI writer for drafting and final checks.

Tips — German-specific best practices

  • Capitalize all nouns: German requires uppercase for nouns. Run the grammar checker with capitalization rules enabled to catch missed cases.
  • Watch commas in subordinate clauses: German often requires a comma before subordinate clauses (e.g., "..., weil ich pünktlich sein muss."). The checker will insert or explain commas.
  • Mind separable verbs: Ensure the prefix is correctly positioned in main vs. subordinate clauses (e.g., "Er ruft dich an." vs. "dass er dich anruft").
  • Check adjective endings: Use the tool to verify endings for strong, mixed, and weak declensions after definite/indefinite articles.
  • Choose the right register: Specify formal or informal tone so pronouns and polite phrasing (Sie vs du) are consistent throughout.
  • Set regional preferences: If your audience is Swiss or Austrian, enable the corresponding dialect option to adjust spelling and word choice.
  • Use the paraphraser for variety: If a sentence is grammatically correct but stiff, try Rephrasely’s paraphraser for natural alternatives.
  • Verify idioms and cultural nuances: Automated tools are strong technically but consult a native speaker for idiomatic or legal text.
