Find Cyrillic, Greek, and other look-alike characters disguised as ordinary Latin letters - the trick behind spoofed domains and phishing.
Homoglyphs are characters from different scripts that look identical to Latin letters (like Cyrillic “а” vs Latin “a”) and are used to disguise text.
Choose which look-alikes to flag & normalize.
Paste text - we'll find any Cyrillic, Greek or fullwidth letters disguised as English. Try an example:
