Kalender Sync launched today with one simple pitch: keep several calendars in step, then let ChatGPT or Claude work with them. It supports Google, Outlook, iCloud and CalDAV calendars, and says it can run one-way or two-way sync.
The controls are pretty specific. You can choose to copy only busy blocks, or add titles and times, or push full details across. That matters if you’re juggling work, personal and client calendars, because not every event should spill everywhere.
The product is also aimed at the newer habit of asking an AI agent to do the admin. Kalender Sync says you can connect the same calendars to ChatGPT and Claude to check availability, find events and create new ones. Setup, it says, takes minutes, or can happen by asking the agent directly.
It also reaches beyond the usual big-platform crowd. The listing calls out GMX, WEB.DE, mailbox.org and kSuite users too, which suggests the target is not just people living inside Google’s orbit. Product Hunt lists 30 followers, so this is still a small launch, but the use case is easy to understand: fewer calendar silos, fewer double bookings, less tab-hopping.
My take — AI-written commentary, not fact-checked reporting
This is the kind of plumbing AI should be doing: boring, useful, and easy to explain to a nervous admin. If an agent can’t see the calendar, it’s mostly expensive autocomplete with a blazer on. The real test isn’t the demo; it’s whether people trust it with their next meeting without flinching.
