Cairn
What's New
Every Cairn release, newest first. Chrome updates extensions on its own
schedule, so it can take a day or two before a new version reaches you.

The tabs you never got round to saving.
-
Crash recovery. Cairn now quietly keeps track of what
you have open. If the browser crashes, is force-quit, or closes
unexpectedly, it offers those tabs back next time you open it —
including the ones you never saved as a workspace.
-
It offers, it doesn’t barge in. Reopen everything,
save it all as a workspace, or review the list and pick. Nothing reopens
on its own; thirty tabs appearing unannounced would be worse than the
problem.
-
It knows the difference between a crash and a decision.
Tabs you closed on purpose are never offered back — only ones that
were open before the browser restarted and didn’t return.
-
It stays on your device. Never uploaded, never records
incognito tabs, discarded after a week, and switchable off in Settings
→ Recover tabs after a crash.

Cairn has a face now.
-
A character who reads the room. The illustrated figure
from Cairn’s videos now stands at the bottom of each tab, and his
expression reflects what’s actually going on — hopeful before
you’ve saved anything, unbothered when things are tidy, and visibly
overwhelmed when the tabs pile up with nothing saved.
-
He reacts to what you do. Save a workspace and you get a
thumbs up. Something fails and he looks alarmed. Delete something and he
stays out of it — that’s your call, not his.
-
He follows your cursor. Quietly, and he looks away again
when you stop moving.
-
He never says a word, never blocks anything, and can be
switched off in Settings → Show the Cairn character.

Choose exactly which tabs go into a workspace.
-
Pick your tabs when saving. Saving a workspace used to
take everything open. Now you can choose — keep All tabs, or
switch to Choose tabs and tick just the ones you want, with
select-all and clear. All tabs stays the default, so nothing changes
unless you want it to.
-
Works when updating, too. The same picker appears on
Update workspace with current tabs, so you can refresh a
workspace from part of your window instead of all of it.
-
Live counts. The tab and group totals update as you
tick, so you can see what you're about to save before you save it.
-
Renamed. Cairn is now listed as
“Cairn — Tab Manager, Workspaces & Session Saver” so
it's findable by what it actually does. Same extension, same data —
only the name on the store listing changed.
1.0.0
August 25, 2026
First public release.
-
Workspaces. Save every open tab as a named workspace —
tab groups, pinned state and order all preserved — then close
everything and restore it in one click.
-
Universal search. One search box across open tabs,
saved workspaces, history, bookmarks and workspace notes.
-
Notes. Each workspace carries its own notes, next to
the tabs they're about.
-
Cleanup. Finds duplicate and stale tabs and suggests
groups from shared domains. Nothing closes or moves without you
confirming it.
-
Temporary tabs. Mark a tab to expire in an hour,
today, tomorrow or a time you pick, and get a reminder instead of
forgetting it in the pile.
-
Optional AI. Ask a workspace to summarise itself or
find themes across its tabs. Off by default, uses your own API key,
and shows you exactly what would be sent before anything leaves your
device.
