9cairns
A personal brain.
The sun rises and the sun sets; and hastening to its place it rises there again.
Blowing toward the south, then turning toward the north,
The wind continues swirling around and on its circular courses the wind returns
9cairns is a private, single-user knowledge system: one place where its owner captures thoughts, keeps a journal, tracks tasks and projects, maintains a personal CRM, and preserves decisions with their reasoning — organized by tags and backed by an append-only evidence record going back to 2003.
It connects to the owner's own accounts to bring his information together. Google integration (Gmail, Drive, Contacts) is read-only and used solely to surface the owner's own email history, files, and contacts back to him — never for anyone or anything else. See the privacy policy and terms.
There is nothing to sign up for — the only account that exists is the owner's.
Cairns are stacked stones that mark a trail. This is where the stones are kept.
