UCals is an AI calendar assistant that changes schedules through natural-language conversation.
What UCals is
UCals is an AI calendar assistant that changes schedules through natural-language conversation. One instruction can make several calendar updates, and later messages can build on the context already established. It organizes scheduling across 11 life categories, including work, meals, exercise, and travel, and syncs in both directions with Google Calendar, Apple Calendar, and Microsoft Outlook. Tools include conflict detection, travel-time calculation, location intelligence, multi-currency cost tracking, learned preferences, and linked events. UCals shows the details before and after a change and lets users reverse the latest update by saying “undo.” Its MCP server connects calendars to Claude Desktop, ChatGPT, Cursor, and other compatible AI assistants. UCals is available on Android, iOS, macOS, and Windows, and offers an API. The company says it uses OAuth 2.0, encrypts data in transit and at rest, and neither stores calendar passwords nor sells, shares, or trains on calendar data. A 14-day trial is available, and the Single plan costs $15 a month, billed monthly. UCals does not integrate with task-management tools.

Who it suits
