Pffff... I'm not going to install LibreOffice for that, or to figure out how to make Gdocs to work with uBlock.
There is a much easier way. Open LLM chat, type there "Proofread please for grammar, keep the wording and the tone as it is, if it doesn't mess with grammar. Explain yourself." and then paste your text. I don't really know what the tools you mentioned do, but any "free" LLM on the Internet will point to things like missing articles, or messed up tenses in complex sentences.
You recommend choosing self-improvement, but I just don't believe I can figure out how to use articles. With tenses I think I can learn how to do it, but I'm not going to. I remember there is some obscure rule how to choose the right tenses, but I was never able to remember the rule itself. I'm bad with rules, it is the reason I chose math as my major. There are almost no rules in math, you are making your own rules. The grammars of languages are not like that, they have rules which can't be easily inferred, you need to remember them. Grammars have exceptions to rules, and exceptions to exceptions, and in any case they are not the rules, but more like guidelines, because people normally don't think about rules when they are talking or writing.
No way I'm starting to learn rules now, I'd better continue to rely on my skills. But LLMs can help me see when my skills fail me.

I believe you (as most of fervent supporters of the rule here) gone too far onto philosophy with this, too far from the reality and practice. You can't detect AI in my messages, because they are mine. Even when I ask LLM to find words for me, it is me who picks one of the proposed alternatives, but mostly I manage without wording changes. I transfer the LLM's edits by hand by editing the source message, so nothing unnoticed can slip into the final result. If I took the effort to ask an LLM to proofread, it means I care about the result more than usual, so I'm investing more effort into it, not less.
