​
Overview

The Profanity Filter uses advanced AI to detect and filter profanity and inappropriate language in both user inputs and AI responses, ensuring all interactions remain professional and respectful. Unlike basic word lists, this guardrail leverages context-aware machine learning to accurately identify explicit, disguised, or context-dependent profanity across multiple languages, with high accuracy and minimal false positives. Designed for enterprise use, the Profanity Filter operates in real time with low latency, helping organisations maintain communication standards and protect their brand reputation.

​
