Syder
What Syder is
Syder is an AI scheduling agent for managing calendars and meeting reminders through web and extension access. Users can message it in WhatsApp using natural language to book, cancel, or reschedule meetings. It syncs with Google Calendar and monitors meetings for scheduling issues. Syder says it calls users 5 to 60 minutes before meetings and reads the event title and notes. Its listed integrations include WhatsApp, Slack, Google Calendar, and Notion, although Notion is marked Coming Soon in plan details. A Chrome extension scanner intended to find meeting details in emails or browser pages is also marked Coming Soon. Syder exposes an MCP server for local agents such as Claude Desktop, Cursor, or Windsurf to read and write calendar data. Monthly plans are Starter at 22.00 USD, Pro at 29.00 USD, and Team at 85.00 USD. A 7-day trial is available without a credit card, but there is no free plan. Syder warns that language-model outputs may be inaccurate and should be checked manually.
