I believe those are tools that use general-purpose LLMs, which aren't tuned for refactoring specifically. So I guess a specifically tuned tool for refactoring will beat those you mentioned in refactoring tasks.
I also imagine a tool that is not AI-driven. While AI will be used for sure for some checks, I believe static checks and other "computable" heuristics will produce better output faster. I don't want to throw a bunch of prompts into AI and sell mediocre-quality software to people.
But overall, I think about what you said, but from another perspective - why have a separate webpage if such of helper can be built into IDE/editor? I think this is harder to do than to create a webpage, but maybe this will be better for users (developers).
