This tool applies the "zalgo" corruption effect to your text by stacking random Unicode combining diacritical marks (U+0300–U+036F, plus a few Cyrillic combining marks for extra flavor) on top of each character. The result looks "haunted", glitchy, or melting — H̷̛͓e̵̗̊l̷l̴o̷ — and is widely used for spooky/horror aesthetics, meme text, and eye-catching social posts.
How it works:
- Each non-whitespace character gets a random number of combining marks stacked onto it.
- Intensity controls the per-character mark count: Light (1–2 marks), Medium (2–4), Heavy (4–8). Higher intensity = more layered, more chaotic.
- Seed (optional): provide a seed to make the output reproducible — the same text + same seed always produces the same corruption. Leave it empty for fresh random output each run.
- Whitespace is left untouched so words and line breaks stay readable.
Reproducibility: the seeded RNG uses a simple LCG (the same approach used by other tools in this collection). With a seed set, you can regenerate identical output later — useful if you want to share a specific "look".
Good to know / caveats:
- Heavy zalgo can render poorly in some fonts and may break copy-paste in apps that sanitize combining characters. If an app mangles it, drop to Medium or Light.
- The combining marks are "real" Unicode characters, so they count toward string length and may affect layout.
- Screen readers will not announce zalgo text sensibly; avoid it for accessibility-critical content.
