Stained Glass Transform is a data protection technology developed by Protopia AI that enables users to interact with Large Language Models (LLMs) without exposing plain-text sensitive data to the LLM provider. The tool is designed for two primary audiences: **Developers and LLM Users:** Protects sensitive information contained within prompts and context windows, allowing teams to use hosted LLM models securely without disclosing confidential data in its original form. **LLM Providers:** Enables LLM providers to integrate Stained Glass Transform into their hosted models, allowing them to serve enterprise customers without requiring access to plain-text confidential enterprise data. The product is positioned to allow enterprises to use Generative AI capabilities with a broader range of internal data, while maintaining ownership and control over that sensitive data regardless of where the LLM is deployed. An AWS sandbox environment is offered for early-access evaluation.
