Daimon: Local Proxy Redacts Sensitive Prompts Before External Large Language Model Inference

Daimon is an open-source local proxy that intercepts LLM requests to sanitize credentials and private identifiers before sending them to external providers. Once the remote response returns, Daimon restores the original local data automatically.
