glin-profanity

What it does

Profanity detection library for JavaScript, TypeScript, and Python that handles evasion techniques like leetspeak, Unicode homoglyphs, and obfuscated text. Supports 24 languages with optional ML-powered toxicity scoring via TensorFlow.js. Includes context-aware analysis for domains like medical, gaming, and technical content.

Why it's useful

Unlike simple word-list filters, it catches evasion attempts like leetspeak and Unicode lookalikes that users commonly exploit to bypass moderation.
