Your calendar, with a little help.
Thereafter is a calendar for Mac. Use it to plan your week, or connect Claude or another AI assistant to check your schedule and make changes for you.
See your day, week, or month, or scroll through an agenda. Keyboard shortcuts help you get around, and you can type a sentence to add an event.
Your weekly 9am meeting stays at 9am when the clocks change. When plans change, edit just one event, that event and all following ones, or the whole series.
Give an assistant access to your calendar through MCP so it can look up events and add or change them. You can also connect locally on your Mac, even offline.
Sign in with a code sent to your email. Support for importing events from Google Calendar and other .ics files is on the way.
