Connect Keeper.sh to Claude and other AI assistants

April 9, 2026 · v2.9.33

Keeper.sh can now be added as a connector in Claude and other assistants that speak the same protocol. Once it is connected, the assistant can see which calendars you have linked, look up the events in a date range and a timezone you specify, and count how many fall inside it — so "what does my Thursday look like" is answered from your actual calendars rather than from whatever you last pasted into the conversation.

You approve the connection once, on a consent screen in your browser, and the assistant signs in with OAuth rather than holding a password. Access is yours to revoke at any point, and revoking it cuts the assistant off without touching the calendars themselves.

At launch this is deliberately read-only. The assistant can look and it cannot change anything, which is the right place to start for something that has your whole schedule in view and occasionally misunderstands you.

New

Visitors in the EU, EEA and UK are asked whether Keeper.sh may use analytics and advertising cookies, and the choice is remembered.

Improved

A connected assistant stays signed in considerably longer before it asks you to connect again.
A calendar you sync into that hits a passing error keeps retrying on the normal schedule instead of being switched off.

Fixed

Connecting Keeper.sh from Claude Desktop goes through, instead of failing before the approval screen.
Events no longer appear on your other calendars, vanish on the next sync, and come back again.
Copies of the same event no longer pile up, one more added on every sync.
Calendars that label times the Microsoft way, such as Eastern Standard Time, now arrive at the right hour.
An ordinary hiccup no longer flags a working account as needing to be reconnected.
A calendar deleted at your provider is switched off instead of failing on every run.
An empty or cut-short error from Google no longer stops the whole sync.
Your calendar list still loads when a provider declines to hand it over.
The checkout window on the upgrade page opens instead of coming up blank.
Starting a Microsoft 365 connection takes you to the Microsoft sign-in page instead of failing immediately.
An occurrence of a repeating meeting moved or retitled on a CalDAV calendar now comes across.
CalDAV servers that return unusable data for repeating events, Lark among them, now sync.
One event copied into two Google calendars is no longer treated as a duplicate of itself.
