 # CuteBlock
 
-CuteBlock is a playful browser extension that replaces likely ad containers with cute animal photos instead of collapsing the page layout.
+CuteBlock is a small browser extension with a simple idea: if a page leaves room for an ad, fill that space locally with something harmless instead of breaking the layout.

-Instead of leaving awkward blank spaces where ads used to be, CuteBlock keeps the original slot shape and fills it with bundled photos of cats, dogs, birds, capybaras, foxes, rabbits, and otters. Bundled photos are the default, so normal use does not make external image requests.
