Your calendars don't talk to each other. Let's fix that.

Your partner adds “Pediatrician 3pm” to the family calendar. CalendarPipe copies it to your work calendar automatically — so you never double-book over school pickups, doctor visits, or the afternoon you're on kid duty.

“My partner added ‘Anna's school play, 2pm’ to our family calendar on Monday. By the time I checked my work calendar that afternoon, it was already blocked off — no standup conflict, no awkward last-minute reschedule. That's when I stopped worrying about missing family stuff.”

Work Calendar

Team Retreat: Barcelona

Mon–Fri, Mar 17–21

Sarah, Mike, +8 others

Multi-day Out of office

Your pipe

Transform to: "Away for work". Deliver as invitation.

Calendar Invitation

Away for work

Mon–Fri, Mar 17–21

Accept | Decline

Works behind corporate firewalls too. When IT blocks third-party OAuth, invitation-based delivery still gets through — because it's just email.

For AI Agents & Developers

Give your AI agent a calendar

AI agents that schedule meetings shouldn't need access to your users' calendars. Give them their own — with real email invitations that just work.

Your agent gets its own calendar

Spin up a hosted calendar with a real email address. No OAuth dance, no user credentials — just an API key.

Real invitations, not hacks

Attendees get standard email invitations they accept in one click. Works with every calendar app. No sign-up required.

Three API calls to production

  • Create calendar, book meeting, done. Cancellations, updates, and notifications happen automatically.

See it in action

1. Create a calendar

Spin up a hosted calendar with its own email address.

2. Book a meeting

Add an event — attendees get a real email invitation.

{ title: "Q1 Review", start: { dateTime: "...T10:00Z" }, attendees: [{ email: "cto@co.com" }] }

3. Cancel — attendees get notified

Delete the event and cancellation emails go out automatically.

Jakub Beneš

“My wife and I share a family calendar. Events tagged with a “J” are ones I need on my work calendar. I couldn’t find a tool that let me set up that exact rule — so I built one.”

Tomáš Růžička

“We wanted calendar sync a developer could extend and a non-developer could set up in two minutes. So we built it.”
