How the Zalgo Text Generator Works
AnyTool generates zalgo entirely in the browser. It iterates over the input by Unicode code point, preserves each base character, and appends a random number of combining diacritical marks from three zones: above (U+0300–U+036F upper set), through or overlay (U+0334–U+0338), and below (U+0316–U+0362 lower set). Combining marks attach to the preceding glyph rather than occupying their own cell, so stacking many of them produces the cascading, glitchy look. Independent sliders set the marks-per-character ceiling for each zone.
- Output is genuine Unicode combining marks, not an image or custom font
- Three independent zones: above, through (overlay), and below
- Per-character mark counts are randomised 0..max by default, or fixed
- Intensity presets range from mini to insane; any zone can be toggled off
- All generation is client-side JavaScript — no server round-trip
