Whatever you use today, Caliyo speaks it.
Full two-way sync with Google Calendar via the official API. Caliyo reads multi-calendar layers, respects free/busy data, and makes its own holds clearly visible so you always know what it touched.
Connects to Microsoft 365 tenants and personal Outlook accounts via Microsoft Graph. Supports mailbox delegation, conditional-access policies, and automatically attaches Teams links when your org requires them.
Syncs with iCloud calendars via CalDAV, keeping iPhone, iPad, and Mac in lockstep. Sync cadence is 1–2 minutes. Read-only subscription calendars are visible to Caliyo for conflict detection.
Ask Caliyo from inside Slack.
No tab-switching, no new app to learn. Caliyo lives right where your team already works.
Caliyo attaches the right video link automatically.
We integrate with fewer things on purpose.
Most scheduling tools brag about hundreds of integrations. We think that creates more problems than it solves—shallow connections that break quietly, scattered data, and a product that tries to be everything.
Caliyo goes deep on a small surface—calendars, Slack, and video links—so the things it does, it does with zero friction. When we add a new connection, it will be native-quality or we won’t ship it.
