BusyShield keeps your busy times in sync across Google, Outlook, and iCloud — plus shareable booking links and an AI scheduling assistant — so you’re never double-booked, while the details stay private.
No credit card required · Works with Google, Outlook & iCloud
Free/busy only by default — your event details never leave their calendar.
Changes mirror within seconds, not minutes — across every connected calendar.
BusyShield only touches the blocks it makes. Disconnect and they vanish.
Real-time sync, shareable booking links, and an AI scheduling assistant — private, reversible, and quietly reliable.
By default every mirrored block is an opaque “Busy.” Titles, notes, and attendees stay where they belong. Need more context on a trusted calendar? Raise the detail level per calendar — you’re always in control.
Got separate Home, Work, and Family calendars? Toggle each one on or off as a source with a click. Turn one off and the blocks it placed elsewhere disappear automatically.
Connect once and BusyShield keeps your availability honest across Google, Outlook, and iCloud — mirroring changes within seconds, with a clear dashboard so you always know everything’s in sync.
Send a personal link and let people grab a time. BusyShield only offers slots you’re genuinely free for — checked against every connected calendar in real time — then drops a real invite on both calendars automatically.
Tell BusyShield what you need in plain English and it reads your real availability to make it happen — block focus time, find a free hour, auto-protect your week. Plus a weekly insights digest and a connector so AI assistants can schedule for you. It only ever analyzes your times, never your event titles.
Sign in with Google, Outlook, or iCloud in a couple of clicks. No browser extensions, no fiddly setup.
Every busy block is reflected onto your other calendars automatically, with echo-prevention so nothing loops or duplicates.
Your availability stays honest everywhere — at work, at home, and on every booking link that reads your calendar.
BusyShield mirrors when you’re busy, not why. By default every block is an opaque “Busy” — titles, notes, and attendees stay where they belong. Connections are encrypted, we never sell your data, and you can revoke access anytime.

Ask in plain English — “block two hours for focus Thursday,” “find me a free hour this week” — and BusyShield reads your real availability to schedule it. It also sends a weekly insights digest and connects to AI assistants via MCP. Only your busy times are analyzed, never event titles.

Connect your calendars once and let BusyShield keep your availability honest everywhere.
