Piast Gate: Open-Source API Proxy for LLM Data Anonymization
What Piast Gate Does
Piast Gate is an open-source API proxy that sits between your application and an LLM. Its core function is to anonymize sensitive data before sending it to the model, then restore the original data in the response. This enables applications to use LLMs with internal or sensitive data without exposing that information to the model. Integration is designed to be simple—just point your application to the proxy.
Current Features
- Automatic data anonymization → LLM request → de-anonymization
- Integration with Google Gemini API
- Polish language support
- Can run locally
- Option to anonymize text without sending it to an LLM
- Option to anonymize Word documents (.docx)
Planned Features
- Support for additional providers (OpenAI, Anthropic, etc.)
- Support for more languages
- Streaming support
- More advanced anonymization strategies
The project aims to make privacy-aware LLM usage easier to implement in real applications. It's currently in MVP stage and the developer is seeking feedback, ideas, or contributions.
