PersonaGraph –
Persistent Personal Knowledge Reuse Across Large Language Models
Remember Once. Use Forever.
About This Series
We introduce PersonaGraph, an architecture for persistent personal knowledge reuse across LLMs, and Knowledge OS, its open self-hosted reference implementation — guided by Remember Once. Use Forever.
This series documents the research, architecture, engineering, and hard decisions behind building a system that treats personal knowledge as durable infrastructure — not disposable prompt context. Each post is a day in the journey from frustration to a working, benchmarked, open-source proof of concept.
Research brand: PersonaGraph — the architecture, the contribution, the citations.
Product brand: Knowledge OS — the code, the Docker image, the thing you run.
