Their recent decision to lock the Firefox extension behind the premium version irks me, but at least self-hosting is pretty easy, and it's still way better than Grammarly

It's too slow. Is there a way to speed it up? I type my entire text/comment and it takes 5-10 seconds AFTER that to start showing the wrongly spelled words.

The red squiggly lines should appear IMMEDIATELY the moment I've made a spelling error. Grammatical ones can take time. But because of its slow speed I hardly ever notice my mistakes until I've posted my comment

good

I bought it for Overleaf, but they broke the compatibility and won't fix it.

Great alternative to Grammly and its free 👍

Après un premier test en français cela à l'air de fonctionner sur toute sorte de faute. On verra dans le temps.
