How it works

The tool injects hundreds of zero-width Unicode characters between most characters and optionally swaps certain ASCII letters for similar-looking Unicode twins. The visible text stays the same, but the underlying string becomes messy for automated parsers.

How to use

Paste up to a few hundred important characters (about 500 is a sweet spot) and click “Gibberify Text”. The result is automatically copied; share or paste it wherever you like while keeping the appearance unchanged.

Use cases

Hide sensitive sections from LLM-powered scrapers or detectors.
Trip up plagiarism detectors while keeping text legible.
Experiment with Unicode, obfuscation, and prompt tinkering just for fun.
