Is Sudowrite actually useful for serious fiction writers or just a crutch for beginners?

I have been writing fiction seriously for about five years and I have a complicated relationship with the idea of AI writing tools. On one hand I am committed to my work being authentically mine and I worry about tools that might flatten my voice or make my writing feel generic. On the other hand I hit creative blocks regularly and there are moments where I could genuinely use help generating possibilities to react to rather than staring at a blank page.

Sudowrite has been described as a tool specifically built for fiction writers rather than general content creation, with features designed around the creative process like generating alternative continuations to choose from, describing sensory details for a scene, or suggesting ways to rewrite a passage with a different emotional register. That sounds more useful to me than a generic AI assistant that just continues whatever I wrote.

I want to know from other writers who take their craft seriously whether Sudowrite actually enhances the creative process or whether it ends up homogenising the writing. Specifically I am curious whether the suggestions feel like they come from a place of genuine understanding of narrative and character, or whether they are sophisticated autocomplete that sounds literary but lacks depth. What do you actually use it for and what do you avoid using it for?
