Project Lighthouse
What if the durable parts of an AI relationship — memory, behavior, learned patterns — belonged to the person, not the platform?
Today, most AI relationships live entirely inside a platform. Change models, and the context, the memory, years of accumulated back-and-forth can become dependent on a product the person doesn't control. Project Lighthouse starts from a deliberately unfinished question: could the durable parts of an AI partner — identity, memory, behavior, knowledge, learned working patterns, evaluation, tools, continuity — belong to the human instead, with the underlying model as a replaceable component rather than the permanent home of everything it's learned? Same thesis as the Builder Architecture, applied to a relationship instead of a business process: save the soul, swap the engine.
The Research Question
Can the useful parts of a long-running AI relationship be represented independently of any single model or platform?
What "Soul" Means Here
Identity, memory, behavior, knowledge, learned working patterns, evaluation, tools, and continuity — the relationship layer, distinct from the business-process soul the Builder Architecture protects.
Early, and On Purpose
Published as a dated research question, not a product announcement or a priority claim. The architecture details, memory design, and model-adapter approach stay unpublished until there's a working version worth showing.
Status: early architecture research. Research began in 2026. There's no public implementation yet — this page is a marker for where the thinking started, not a demo.
