Creepy Text Generator

How it works under the hood

Unicode includes a block called Combining Diacritical Marks (U+0300 to U+036F) plus extensions. These characters do not stand alone, they attach to the previous base character. “e” + U+0301 (combining acute) renders as “é”. The spec places no real limit on how many you stack. Zalgo takes advantage by stacking dozens.

For each letter, the generator appends as many random marks as the intensity value says, from 1 to 15. The mark set mixes combining marks that render above the letter (like U+030D, U+030E, U+0301) with a few overlay marks (like U+033F, U+0342). Because most of the marks sit above the line, high intensity stacks them upward, which is the classic zalgo look.

Where it works (and where it does not)

Many platforms now cap the vertical overflow visually (clipping the marks to one line-height) to prevent chat lines from eating neighbours. The text still goes through, it just looks less chaotic.

Tips for usage

• Keep it short. Long zalgo blocks look like spam and get flagged.
• Avoid usernames. Many sites normalise usernames, stripping the marks, or block them outright.
• Consider accessibility. Screen readers will either skip combining marks entirely or speak them painfully, not ideal for announcements.
• Search and copy behave oddly. A zalgo word cannot be found with normal search, which may be the point or may cause trouble.

Quick reference: mark types

• Above: circumflex, acute, grave, diaeresis, macron, ring, hook. Visually dominant.
• Middle: tilde overlay, slash, stroke. Subtler.
• Below: cedilla, comma, ogonek, macron below. The “drip” effect.

The generator draws from the whole mark set at every intensity, so high values simply pile on more marks. For a milder, spikier effect, keep the intensity low.
