Zalgo text stacks random combining marks above letters to create a corrupted, glitchy look popular for horror themes and memes.

Use the intensity slider to control how many marks are added, from a light distortion to a heavily cursed effect.

The result is made of real Unicode characters, so it can be pasted into posts and chats, though some apps limit how much stacking they show.
