What Syder is
Syder is an AI scheduling agent available through the web and an extension. Users can message it in WhatsApp to book, cancel, or reschedule meetings with natural-language requests. It syncs with Google Calendar, monitors meetings for scheduling issues, and says it calls 5 to 60 minutes before an event to read its title and notes. Listed integrations include WhatsApp, Slack, Google Calendar, and Notion, although Notion and the Chrome extension are marked Coming Soon in plan details. The service exposes an MCP server for local agents such as Claude Desktop, Cursor, or Windsurf to read and write calendar data. Syder describes itself for founders, sales representatives, and remote teams. There is no free plan; monthly plans are 22.00 USD, 29.00 USD, and 85.00 USD. A 7-day trial requires no credit card. Syder warns that language-model outputs may be inaccurate and should be checked manually.
