Homoglyph Detector
Free online homoglyph detector. Find suspicious lookalike Unicode characters from other scripts in your text.
About This Free Online Homoglyph Detector
Our free homoglyph detector scans your text for lookalike characters from other alphabets, the deceptive symbols that look identical to ordinary letters but are actually different Unicode characters. For example, a Latin a can be swapped for a visually identical Cyrillic one, a trick used in phishing links, spoofed usernames, and scam messages. Paste your text and the tool flags every suspicious confusable character instantly, showing you where hidden substitutions are hiding. It is valuable for security checks, content moderation, verifying domain names and brand mentions, and cleaning up text that may have been tampered with. Catching homoglyphs by eye is nearly impossible, so an automated detector is essential. Everything runs locally in your browser, so it is immediate, free, requires no signup, and your text is never uploaded.

Frequently Asked Questions About Homoglyph Detector
What is a homoglyph?
A homoglyph is a character that looks like another character but has a different Unicode codepoint. For example, Cyrillic "а" (U+0430) looks identical to Latin "a" (U+0061) but is a different character.
Why should I detect homoglyphs?
Homoglyphs are often used in phishing attacks (lookalike domains) and can cause issues in text processing, search indexing, and content validation. Detecting them helps ensure text authenticity and security.
Why Choose the Homoglyph Detector?
Good analysis needs to be both fast and private. The Homoglyph Detector processes your text locally and shows results as you work, so you can iterate on drafts and data freely, knowing the content is never transmitted or stored.
