A personal dictionary feature allows users to add custom words or exceptions, ensuring the checker learns their specific vocabulary.
LanguageTool is compatible with most online platforms, including email services like Gmail and social media sites such as Twitter and LinkedIn. The developer, LanguageTooler GmbH, emphasizes user privacy, stating that text is checked via a secure, encrypted connection to languagetool.org, and personal data like IP addresses are not stored. This commitment ensures users can write with confidence and control over their content.
