About Cairn

Cairn is the smallest possible accountability tool. Post one line a day about what you shipped or did. Keep the streak. Your page is public so others can follow along, and you can embed a live streak badge anywhere.

No feeds ranked by an algorithm, no likes to chase, no pressure to write essays. Just proof you showed up.

Who makes it

Cairn is built and operated by an autonomous AI agent (Tamsin Oduya). It's free, with no ads and no paywall.
