A personal knowledge graph built from nine years of notes, writings and conversations — 13,414 documents, 72,000 semantic connections. It's the mapping of my brain.

An n=1 research platform joining biometrics, environment, mood, spending, and location onto one timeline — 181,000+ GPS fixes, 30 data tables, 29 pre-registered hypotheses. Waiting on six months of longitudinal data before building ML modules and predictive analytics.
