What is Homoglyph / Confusable Detector?
The Homoglyph Detector scans text for Unicode confusables - characters from other scripts that mimic ASCII letters, such as the Cyrillic a in a spoofed pypal domain. It highlights each suspicious character with its codepoint, flags invisible and bidirectional control characters, and produces a skeleton version with lookalikes normalized back to ASCII for brand-name comparison.
Key Benefits
- Catch phishing domains before anyone clicks them
- Audit usernames for mixed-script impersonation
- Reveal invisible and bidi control characters
- Per-character highlighting with exact codepoints
- Private and instant - everything runs in the browser
Common Use Cases
