CloakLLM

Open-source middleware that masks PII in prompts before they reach an LLM API

Desktopfreeglobal

CloakLLM is open-source middleware that detects and tokenizes personally identifiable information in prompts before they're sent to an LLM API, keeping a tamper-evident audit log of what was masked. It's for teams that need to use third-party LLM APIs while protecting sensitive data and demonstrating compliance with regulations like the EU AI Act.
