Are there any plans for a LibreOffice extension?

I started vibecoding one a few hours ago. But I'm expecting to hit a dead end without anybody else helping.
This is because I already hit dead ends trying the same for IntelliJ, Xcode, and Eclipse.

Follow the main GitHub issue here: #1427

Hello! I recently discovered this great FOSS grammar checker and have finished integrating Harper as an option into my LibreOffice extension. It also supports LLMs / LanguageTool. It's currently async, so there can be delays showing errors, but I'll work on shortening latency later. The settings are saved with the file. If you re-open a saved file, they will all be there.

The extension has a bunch of other interesting AI / Python features, however you can just use the grammar checker by itself. The feature is under Settings -> Doc, choose Harper as the grammar checker.
