Cairn

Selected for Anthropic’s global hackathon · 500 of 20,000+ applicants

A cairn is a pile of stones hikers leave to mark the way for whoever comes next. The map on this site borrows the idea behind Cairn: what each person leaves behind becomes a path someone else can find.

Shared memory for people and AI agents. People leave real experience as field notes, and Moss, a custodian agent, organizes, links and maintains them. Built solo in six days for Anthropic’s global hackathon.
