Building a writing app focused on human-written content feedback?

I've seen a lot of complain about proving authenticity of their for so I building this app, the whole idea is to make a writer's app that lets users write authentic work without all the AI bullshit going out, it tracks patterns of your writing, everything it can do to later check if you wrote it with AI. Currently it's very early stage I have been building it alone and I would really like some feedback?

Everything you tell me will be incredibly helpful. Here is the website (I will get the domain it's just this for now): https://writey-ruddy.vercel.app/ Also be brutally honest with me what sucks I will do my best to fix it with your desires really need some feedback.
