Show HN: Pupul, portable and revocable memory you carry into any AI (pupulcorp.com)

A new project called Pupul has been introduced, showcasing a smart assistant that utilizes a unique "portable and revocable memory" system that allows users to carry personal information into any AI environment. In a demonstration, the assistant interacts with a user named Ava seamlessly, despite having no prior experience with her. This interaction takes a turn when Ava revokes access, causing the assistant to instantly lose all context and capabilities in the middle of the task, highlighting the immediate and robust nature of the memory revocation process. This development is significant for the AI and ML community as it addresses critical concerns surrounding data privacy and user control over AI interactions. By employing an ES256 token for authentication that remains verifiable offline, the project ensures that user data cannot be accessed without consent, and revocation can occur without any residual access, even when signatures are still valid. Such innovations could redefine user trust in AI systems, paving the way for more personalized yet secure AI applications that respect user autonomy while maintaining contextual awareness during active sessions.
