Breaking AI Context Silos: A Proposal for a Portable Memory Protocol (PMX)

I have been exploring how AI tools could share and reuse “memories” instead of locking them inside their own apps. Today, context is fragmented - if you switch assistants or LLMs, your history does not follow you.

This post outlines a proposal for PMX - Protocol for Memory Exchange, a neutral JSON-based schema for portable, user-owned context. It aims to standardize how memories, embeddings, attachments and source provenance can move between different AI tools and apps.

I built a small reference implementation to test it, but I am mainly looking for feedbackk on the protocol design and any missing pieces.
