AI Output Filter Builder

Build content filter rules for LLM output: blocked words, regex patterns, PII detection, and format constraints.

Design a complete content filter configuration for LLM output. Add blocked words/phrases, custom regex patterns, enable PII category detection (email, phone, SSN, credit card, IP), and set format constraints (max length, must-contain-JSON). Generates a JSON config and includes a live test panel to validate your rules against sample output.

FAQ

What does the generated JSON config contain?
The config includes an array of blocked words/phrases, an array of regex patterns, a list of enabled PII categories with their detection patterns, and format constraints like maximum length and required JSON structure.
How can I use the generated filter config in my application?
The JSON config is designed to be loaded as a runtime configuration object. Parse it server-side and apply each rule to LLM output before returning it to users. You can implement the matching logic yourself or use it as configuration for moderation middleware.
Can I test the filter before deploying?
Yes — use the built-in test panel to paste sample LLM output and see which rules trigger. Matches are highlighted inline so you can tune your rules before integrating them.
