§ about · short version

A small piece of software for a careful kind of work.

No team page, no founder story arc, no "trusted by." A page of facts, a short reading list, and the colophon.

why this exists

n1lab is made for the kind of person who has already kept a paper list of foods, who has tried the protocols, and who has come away from both with the suspicion that the careful thing is to write it down for longer.

the long version

The product

n1lab started as a paper notebook. Two columns: what I ate, what I noticed. After eighteen months it became clear that the notebook was lying to me — not on any given day, but across weeks. Memory had been quietly editing the entries.

The software exists to remove that editing. Every reading sits next to the last one, scaled the same way, on the same baseline.

The work was paused twice. It restarted because the paper notebook came back, and the paper notebook was not enough.

The person

n1lab is built by one person.

The author is not a doctor. The author has spent ten years building software for other people's data and a smaller number of years building software for their own. This is the latter.

There is no team page because there is no team. If a question reaches the inbox, Sean answers it himself.
