Personal Portable Memory

Personal Portable Memory (PPM) is a research initiative to develop the open public infrastructure needed for individuals to own, control, and benefit from persistent AI capabilities across every stage of life. Rather than allowing personal knowledge, preferences, experiences, credentials, and interactions to become locked inside proprietary AI platforms, the initiative explores the standards, protocols, governance models, and reference implementations needed to make personal AI portable, interoperable, and user controlled.

Advancing the next generation of personalization requires a new foundation: portable, persistent personal memory — a user-governed layer of context that persists across interactions, moves across tools, and can be shared selectively by role, consent, and purpose.”

The Human Context Protocol serves as the foundational interoperability layer for this infrastructure, enabling AI systems to exchange user-authorized context while preserving privacy, provenance, and individual control.
