If you want people to believe your project is not slop while using AI, the absolute least you could do is write the copy yourself. If you worked a long long time, morning to night, you can spend 10 minutes writing in your own words what your project is, why you're passionate about it, and why it's cool or useful. Slop in the copy is an overwhelmingly strong signal that there's slop in the code and design. After all, if you can't even be bothered to take 10 minutes to write about your project yourself, which doesn't even take particular skill, who is going to believe that you put hundreds of hours of skilled labour into it? Maybe you really did, but you certainly aren't sending the signal that you did, and signals are a heuristic people use to filter out noise because it's too time and energy consuming to deal with unfiltered noise.
