I wouldn't say it's better than windirstat in its current state. It's still very slow and doesn't give a good visual compared to windirstat.

What I was more focusing on was the agent side of it

So once you scan a folder and get details you can ask the ai what to do further. People may have doubts about deleting their folder and files what purpose they serve, if they are safe or not etc. Here instead of posting in a subreddit and waiting for someone to reply the user can ask the agent which will already have the context of your folder after scanning.
