Our verdict on Rechtschreibprüfung24
Rechtschreibprüfung24 is a web-based grammar and spelling checker for German and other languages. It checks spelling, grammar, punctuation, syntax, style, redundancy and readability, while also providing word-density and filler-word analysis. It suits individuals and organizations that want browser-based writing assistance, particularly German web users who need AI correction or rewriting alongside conventional language checks. Registered users can save texts, load documents, use a personal dictionary and find synonyms.
The free plan covers spelling and grammar checking, many languages, readability and word-density analysis, filler-word analysis, printing and PDF creation, with a maximum of 20,000 characters. The Werbefrei plan adds ad-free use on rechtschreibpruefung24.de and AI functions without a daily limit while retaining the free functions. Werbefrei + KI includes the same listed benefits at €4.50 per month with monthly billing. The published plans make the paid options most relevant to users who want uninterrupted AI access or an ad-free web experience.
Its standout breadth is the combination of language analysis, AI rewriting, document import and photo text extraction in one browser-focused service. AI tools can correct, rewrite, shorten and expand text, while synonym suggestions and a personal dictionary support more controlled editing. Platform access includes the web, API and Chrome extension, and Microsoft Word is referenced through a partner LanguageTool offering. Choose Rechtschreibprüfung24 if browser-based editing, German-language support and AI writing functions matter most; choose another tool if your workflow depends on a broader native desktop or mobile application experience.
