what is the script analyzer?

In roblox studio I got this stupid thing in the output called script analyzer and I really want to get rid of it anyone know how?

This is probably some script that you have inserted into the place, from free-models.

If it occurs in all places that you open (including blank ones) it's from a plugin that you have added to Studio. Re-evaluate which ones you have included (see Tools -> Open Plugins Folder).

I think the specifics of deleting a particular object that you have, yourself, put in a place is not in the scope of this website, so I wish you luck.
