CogniVault is a secure, privacy-first platform designed to empower individuals with full control over their personal data generated by AI-powered devices and services. As “always-on” AI becomes prevalent (e.g., smart glasses recording conversations, AI fitness coaches, smart home devices), CogniVault acts as a centralized, encrypted vault where users can aggregate, manage, and derive insights from their personal data streams (e.g., health metrics, conversational summaries, journal entries, photo metadata). It solves the problem of fragmented data, privacy concerns, and lack of user control by providing a unified dashboard, allowing users to apply privacy-preserving AI models to their own data, and granting explicit permissions for data sharing or insight generation.
