Installing a Local LanguageTool Server (optional):
For maximum privacy and control, you can run your own LanguageTool server locally. This is especially useful if you want to check sensitive texts or avoid using the public API.

1. Download LanguageTool from languagetool.org and extract the archive.
2. Start the server with the gui (languagetool.jar) or in the extracted directory with:
   java -cp languagetool-server.jar org.languagetool.server.HTTPServer --port 8081
3. For more details and advanced options, see the official guide: LanguageTool HTTP Server Guide
