AddCal is an event-sharing platform that helps creators and organizations make it easier for people to attend. Its core tool generates a single add-to-calendar link that works with Google, Apple, Outlook, Office 365, and Yahoo, allowing guests to add events without downloading an app or creating an account. Users can create links quickly, edit event details after sharing, and track views, clicks, calendar adds, and audience data.

The platform also offers RSVP forms with custom questions, capacity limits, waitlists, dashboards, and CSV exports. Subscription calendars keep future events and schedule changes synchronized for subscribers, while Smart Links generate personalized events from URL parameters, webhooks, or Zapier. Other services include branded public event pages, embeddable calendars and buttons, automated reminders, team collaboration, custom domains, and an API. AddCal serves webinars, classes, school events, product launches, meetings, and other gatherings. It offers a free plan with unlimited calendar adds and clicks, alongside paid features and business options. The company also provides documentation, support resources, and one-click migration from AddEvent.
