BusyBoard

BusyBoard is one link that shows when you're actually free, across every calendar you own. Connect multiple Google and Outlook calendars and they mirror each other, so you're never double-booked. You get a single availability link people can book from, with a privacy guarantee: no event titles, descriptions or attendees are ever stored or shown, only busy and free. AI agents get the same view. Point Claude, ChatGPT or any MCP client at your BusyBoard and it can read your availability and book into it without seeing what's on your calendar. Once your people are on BusyBoard, create a group and pick who needs to meet. Your team of three and the client's team of five see the overlapping free time instantly, no "when works for you?" thread with eight people on it. Free for one calendar and one link. Pro adds unlimited calendars, mirror modes, instant sync and agent write access.
