Live grammar checker

Hello!

I've been using Silverbullet and especially love the fact that I can self-host it, and then access my instance via any device, it makes it very convenient to write on.
However, it does not have grammar checking. I realise that Silverbullet is not exactly geared towards this, so I wouldn't be surprised if this idea is rejected as being out of scope (since I imagine it to be a considerable undertaking).

The idea/feature request is to incorporate grammar checkers, updated live while writing.

There is a lovely plugin written by a fellow SB user, over here, but it's clunky and limited - I need to type a command each time, and from what I know SB doesn't support underline/hover messages.

This would effectively give users (or just me, would anyone else do this? haha) a single place, synced and accessible from anywhere, to, well, write, not just take notes.

Thanks.

Edit to clarify: I realise Grammarly is a thing but I'd like to use a FOSS solution like LanguageTool or Harper.

I had initially written this post because I wanted something integrated into the page itself rather than need to install extensions.

However, I have now realised that not even extensions work, maybe the custom code editor is throwing them off? Neither the LanguageTool nor Harper extensions detect anything in Silverbullet, both in Firefox and Chrome, so grammar checking isn't possible whatsoever. I'm running SB 2.9.

Should I post this in Issues?

I've made some updates to the grammar checker plugin. It's not perfect, but it supports underline messages through the editor's linter.
