A time to gather stones
A journal for observations, decisions, and wishes.
Cairn gathers your stones — and finds patterns in your trail.
Free · No ads · Only your trail
Every stone has its own nature
Notice
Something caught your eye on the trail. Picked it up, put it in your pocket — let it settle.
Lay
The stone is placed with intention. Cairn will ask a couple of questions and remind you to return — when the time is right.
Cast
A coin in the fountain. Thrown forward and released — but not forgotten. Cairn will bring it back later.
Three gestures — and the trail leads
Write down an observation, decision, or wish. For a decision, Cairn asks two clarifying questions — so you understand for yourself what's behind the choice.
Stones rest without hurry. A week, a month, a year later — Cairn sends a reminder: "A stone calls you back to the trail." Return if you wish.
When enough stones have gathered, Cairn analyzes them all at once and surfaces patterns — themes that repeat not because you looked for them, but because they're there.
Cairn uses Claude — Anthropic's language model — to find the threads running through your entries. Not by keyword, but by meaning.
Patterns appear automatically once enough stones have gathered. Save a meaningful one to Cornerstones — an archive of what matters most.
You return to the theme of self-expression again and again — through writing, speech, professional choices. That's not a coincidence.
Your observations often appear on Monday mornings. It seems you think about life in the gaps between things.
Many of your decisions are about choosing between safety and risk. Interestingly, you always describe the "safe" options in less detail.
"The stone the builders rejected became the cornerstone."
Psalm 118:22
Cairn is not a task manager. Not a productivity journal.
It's a place to put what seems important — without knowing why.
Over time, you'll start to see the shape these stones make.
