hi-time & hi-money

The Problem

Seven years ago I started logging every hour of my day, just to gamify life. When AI arrived, I realized all that structured data could mean something — if I could get it in front of AI without needing a database or API integration.

What We Built

Built hi-time and hi-money as frontends that automatically sync to a markdown vault. Markdown is an LLM's native language — one line like `09:00-11:30 | W` and the AI knows exactly what you did that morning. The vault becomes a personal data center; every AI conversation starts from there.

Impact

• •AI can now plan my week with full context — it noticed I'd worked 45 hours, my rest ratio was dropping, and I had a Korea trip coming. Zero extra prompting needed.
• •The system learned my patterns: it caught that I'm interest-driven and spend evenings on unplanned things, then told me to design around it.
• •Seven years of data. One markdown vault. Any AI can read it.
