Stop carrying your team's decisions in your head.

Cairn turns messy Slack threads and meeting notes into a searchable record of what was decided and why in under two minutes.

Built by Product Managers, for Product Managers. The tool I needed and couldn't find.

Your team made dozens of decisions last quarter.

You were in the room for most of them. So was your Slack. So were your meeting notes. But three weeks later someone's asking why the thing works the way it does, and the only place that answer lives is in your head.

That's not a documentation problem. That's a you-as-single-point-of-failure problem.

1. Send to Cairn

Flag a Slack thread, email chain, Jira ticket, or meeting notes for Cairn

2. Cairn goes to work

Cairn pulls out the decision, the reasoning, who made it, and what was considered

3. Never forgotten

It's saved, searchable, and shareable with a link you can drop anywhere

You review before anything saves. You edit anything the AI gets wrong. The structure is there. You just confirm it.

The Receipt

The moment it earns its keep is the meeting where a leader confidently contradicts a decision they were part of making.

You open Cairn. You find the card. You share the link. Meeting over.

Who's It For

Cairn is for PMs who are the connective tissue of their team — the ones who were in every decision, remember most of them, and are tired of being the only one who does.

If you've ever sat in a meeting watching a leader contradict something they signed off on three weeks ago, onboarded someone new and had to rebuild months of context from scratch, or spent 20 minutes finding the reasoning behind a call that took 2 minutes to make — this is for you.

Cairn is in beta.

The first 50 people to sign up get their first 2 months free. Most waitlist signups are getting access within two weeks.

Built by PMs, for PMs. The tool I needed and couldn't find.
