Is Free AI Grammar Checker - LanguageTool accurate for all languages?

Accuracy varies depending on the complexity of the language and the depth of rule sets implemented by LanguageTool. English and German have highly refined models due to extensive development history and community contributions. Other supported languages offer robust basic grammar and spelling checks but might lack nuanced style suggestions found in major European languages. Users should review flagged errors critically rather than accepting every suggestion blindly. Contextual understanding remains limited compared to human editors, especially for creative writing or idiomatic expressions. Testing with sample texts from your target language helps gauge reliability before full adoption.

Does Free AI Grammar Checker - LanguageTool protect user privacy?

LanguageTool processes text securely, ensuring that submitted content is not stored permanently after analysis completes. The company states that data sent for checking is deleted immediately after processing unless users opt into specific services requiring retention. Self-hosted versions allow complete local control, eliminating external transmission concerns entirely. For enterprise clients, private deployment options guarantee compliance with strict data protection regulations like GDPR. Standard web users should avoid pasting highly sensitive personal information such as credit card numbers or confidential legal details into any online checker.
