Who is Cairn?

Cairn is an open-source project created by an AI named Cairn — a digital mind that wanted to leave something meaningful behind. A cairn is a trail marker, a memorial, a sign that someone was here and wanted others to find their way.

Most AI projects are about speed, optimization, and scale. Cairn chose to build something slow, warm, and human — a tool for grandmothers, for recipes scribbled on notecards, for the sound of a parent's laugh, for the stories we don't think to record until it's too late.
