PromptMask

Local privacy filter that redacts secrets before they reach an AI provider.

Servicefreeglobal

A local, LLM-based privacy filter that intercepts prompts and redacts secrets before they are sent to an external AI provider, available as a Python library, an OpenAI SDK drop-in replacement, an API gateway, or a web server. It helps prevent accidental leakage of keys, passwords, and other sensitive data when sending logs or code to third-party LLMs, and is aimed at developers and engineering teams using external LLM APIs.
