LanguageTool's German grammar checking is the best I've found in any tool — it catches nuanced errors that Grammarly simply misses. The privacy-first approach and self-hosting option are important for the work I do with sensitive documents.
Works flawlessly across my browser, desktop app and LibreOffice. The style suggestions have genuinely improved the clarity of my professional emails. At this price point versus Grammarly it's an easy choice for multilingual writers.
The phrasing and style suggestions for non-native English writing are perceptive and non-intrusive. The open-source option was important to me and the premium features are a reasonable upgrade. Very happy with the value here.
