As someone who loves homebrew stories with clever twists, "long term" hints for future plots and picking up ideas from the players to weave into the current story on the fly ... it would not be the same for me. It might work well for generic solo play for a couple of evenings just to kill time, but I wouldn't expect an AI to create something more elaborate than "go there, kill this, loot, XP, next quest"... and that's a concept I usually find boring pretty fast.
That being said, if it brings you joy then there is no need to ask internet strangers for approval. Don't let it sour your mood if others might or might not like the same things as you, and just enjoy what you enjoy ;) The world really doesn't need any more gatekeeping.
