Obscurit.app

Not until you install it do you find that this is a costed product - you can't even try it before you buy it - this sort of thing should be clearly stated on the Chrome store and the description, the obscure (sic) "contains in-app purchases" hides the fact that it is unusable until you pay

Great for blocking annoying twitch chats in youtube videos.

Great widget for content-blurring I need for screensharing via Zoom/ MS Teams. Highly recommend!

worked really well for webinars and tutorials that I do.
