Deep Unicode code point, grapheme cluster, and Trojan Source analyzer.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
A code point is an individual Unicode numerical value, whereas a grapheme is a user-perceived glyph (e.g. an emoji with a skin-tone modifier consists of multiple code points but is 1 grapheme).
It flags invisible directional format characters (such as RLO, LRO, LRI, RLI) that can manipulate code presentation in text editors to obscure malicious logic.
