Word Add In Native Integration Without Context Switching

via “desktop application integration for native text editors and email clients”

Open-source multilingual grammar checker for 30+ languages.

Unique: Integrates LanguageTool checking into native desktop applications (Outlook, Word, Pages, Mail) through unknown system-level mechanisms, extending checking beyond browser-based writing to professional productivity tools

vs others: More integrated into native Windows and macOS workflows than browser-only solutions, though integration mechanism and performance characteristics are undocumented compared to Grammarly's native application support
