The NaNo communities in cities were fun gatherings of people talking about their creative projects, and people posting fun bits from their current work. Now it's just raw feedstock for Liar Clippy in the new incarnation. Though honestly cover letters could use long omegaverse detours. Go for it.
So, wait, has NaNoWriMo rebranded as "Novel November", paid for by ProWritingAid, which used to be a spell/grammar checker but now is (you guessed it) an "'AI' grammar checker"--in short, yet another way for a griftslop machine to grab human-written text? Do I have that right?
