Homoglyph & look-alike letter detector

Some letters from the Cyrillic and Greek alphabets look identical to Latin ones. Scammers use them to build fake links and brand names, like a Cyrillic “а” in “аpple.com”. Paste text to see every look-alike highlighted.

Removes only what you cannot see. Every visible character is left exactly as it was.

Why homoglyphs are dangerous

To your eye, paypal.com and pаypal.com are the same. To a computer, the second uses the Cyrillic letter “а” (U+0430) and points to a completely different website. Homoglyph attacks are used in:

  • Phishing links and look-alike domain names
  • Fake sender names and brand names in emails and DMs
  • Usernames that impersonate real accounts
  • Evading keyword filters and moderation

How ClepBoard decides what’s suspicious

Flagging every Cyrillic letter would break genuine Russian, Ukrainian or Greek text, so ClepBoard is more precise:

  1. A look-alike letter inside a word that also contains Latin letters (like “pаypal”) is flagged. Real words don’t mix alphabets.
  2. A word made entirely of look-alikes inside otherwise English text (like “РАУРАL”) is flagged.
  3. Genuine Cyrillic or Greek sentences are left untouched.

Flagged letters are underlined in red in the X-ray view; hover one to see which alphabet it’s from. The clean copy replaces each with the Latin letter it imitates.

FAQ

Does this check whether a link is safe?

It reveals look-alike letters, which is one of the most common tricks in fake links. It does not check a website’s reputation, so still be careful with links you don’t trust.

Will it break my Russian or Greek text?

No. Words written fully in Cyrillic or Greek are left alone unless they sit inside otherwise English text and are made only of Latin look-alikes.
