Hush is a Semantic Security Gateway that protects sensitive data when using AI coding tools by redacting personally identifiable information (PII) like emails, IP addresses, and API keys before they leave your machine. It acts as a local proxy between AI tools (Claude Code, Codex, OpenCode, Gemini CLI) and LLM providers, replacing sensitive data with deterministic tokens that are rehydrated locally while the provider only sees the tokens. This tool is designed for developers and teams who want to use AI coding assistants while maintaining privacy and security of their sensitive information.
