Overview
Calendar0 is a unified calendar application for the web and desktop (macOS, Windows, Linux) that integrates Google Calendar, Microsoft 365/Outlook, and Apple iCloud calendars into a single view accessible from your menu bar or system tray. Users can schedule meetings by typing natural language requests like "lunch with Sarah tomorrow" which the app converts into calendar invites, eliminating the need to fill out multiple fields.
The application includes an AI assistant that helps with calendar management tasks, meeting recording with automatic transcription and AI-generated notes, and booking links for scheduling. Calendar0 also works inside AI apps like Claude and ChatGPT through an MCP connector. The product is independent and founder-run by Alessandro Afloarei through AFL Solutions, with no venture backing or separate sales team.
