Keep everything in one place, then let AI go looking.

Sort your links, notes, and half-read clippings by hand — or hand the pile to AI and let it surface the corners you forgot about. Our browser extension means you are always one keystroke from saving what matters.

A gentler way to hold data.

Toolbars, forty open tabs, a bookmarks bar nobody has opened since 2019. Cairn boards are visual, searchable, and shareable — and quietly improved by suggestions you can ignore.

Bring the whole crew along.

Boards work the same for product teams, households, and group chats. Whether you are chasing a quarterly number or splitting a move-out checklist, the workflow holds up.

Features

Just enough structure to finish things.

Organize your way

Leave everything in one heap, or break it into stacks. Cairn does not have an opinion about it.

AI helper

Board Builder drafts the first version for you, so you never have to stare at an empty board.

Browser clean up

Forty tabs deep? Sweep the whole window into a board in about two clicks.

Prioritize

Drag cards up and down in Kanban view so the whole team can see what is genuinely urgent.

Table view

Get a flat, sortable read on everything at once, then group it back into stacks when you are done.

Structure your data

Add custom fields — due dates, owners, addresses — and the board quietly becomes a real database.

Yes, there's a podcast.

Join co-founders Mira Delgado and Theo Rask each week as they argue about what it takes to build software people can actually live with.
