Make AI agents that never see your data
Astra is a cutting-edge SaaS tool designed for developers and data privacy professionals who need to build AI agents without exposing sensitive information. Its core innovation lies in tokenizing protected health information (PHI), payment card information (PCI), and personally identifiable information (PII) before data reaches the AI model. This approach ensures that raw sensitive data remains unseen by the AI, significantly reducing privacy risks while maintaining the model’s ability to reason and act on the data at execution time. Astra’s simplicity—just two lines of code—makes it accessible for integration into any AI agent framework, making it ideal for teams prioritizing security and compliance without sacrificing efficiency or functionality. Its unique approach to data anonymization enables organizations to deploy AI solutions confidently where data sensitivity is paramount, such as in healthcare, finance, and legal sectors.
