I built an extension that adds an AI writing copilot directly into your LibreOffice Writer sidebar. That way, you don’t need to switch back and forth between Writer and ChatGPT.

The extension only runs OpenAI's GPT-5-mini model at the moment. Just wanted to release a bare-bones MVP ASAP; figured I should pick OpenAI for the instant name recognition.

The extension is free, but you’ll be charged for using the OpenAI API.

I’m running a Django Ninja server as a middleman between the extension and OpenAI. Building, packaging, and troubleshooting the extension is tricky, so I wanted to move as much complexity out of it as possible.

It’s been published on the LibreOffice extension directory: https://extensions.libreoffice.org/en/extensions/show/99471 .

There’s a lot of stuff I could add (local models, free hosted models, UI enhancements, etc). But I don’t have much time in the evenings, and I’m not sure what’s the next most important thing to do. Any feedback/suggestions would be much appreciated!
