How does it handle words like 'assistant' that contain profanity?

The API uses semantic and dictionary layers to understand word boundaries and meaning, preventing 'the Scunthorpe problem' where innocent words are flagged for containing substring matches.

What are the 5 layers of detection?

The layers are: L0 (Custom Blocklist), L1 (Static exact match), L2 (Dictionary semantic matching), L3 (Semantic phrase understanding), and L4 (LLM for human-like judgment).

Does it work for real-time chat?

Yes, the 'Instant' mode is designed for sub-5ms or sub-15ms response times, making it suitable for high-volume real-time messaging.

Can I white-list specific words for my community?

Yes, the API supports custom allowlists per request, allowing terms like 'weed' to be permitted in gardening forums while remaining blocked elsewhere.

What is 'Smart' mode?

Smart mode is an adaptive routing feature that only triggers the LLM layer when the faster, lower-cost layers provide conflicting results.

About The Profanity API

What the tool does and who it's for

The Profanity API is an advanced content moderation solution that utilizes a sophisticated 5-layer analysis pipeline to detect offensive language. Unlike traditional keyword filters, it employs a combination of static blocklists, semantic word matching, phrase-level understanding, and LLM-powered human-like judgment. This multi-layered approach allows it to distinguish between harmless banter (e.g., in gaming or creative writing) and actual toxic behavior or threats. It offers specialized contexts such as child_safe, medical, and professional to minimize false positives while maintaining high accuracy.

Key capabilities

5-Layer Analysis: Processes content through blocklist, static, dictionary, semantic, and LLM layers.

Context Awareness: Differentiates between intent in various settings like gaming, medical, or creative writing.

Smart Routing: Uses expensive LLM analysis only when lower layers disagree, optimizing cost and speed.

Multiple Operating Modes: Offers 'Instant' (<5ms), 'Balanced', and 'Strict' modes for different needs.

Intent Categories: Specifically flags discriminatory, abusive, threatening, and sexual content.

Customizable Filters: Supports per-request custom allowlists and blocklists.

Detailed Debugging: Provides layer-by-layer breakdown and match positions in API responses.

High Performance: Instant mode provides sub-15ms response times for high-volume chat.
