Syder review
Chat-based scheduling for Google Calendar users, with monthly plans starting at $22.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Syder is a web-based AI scheduling agent for professionals, founders, sales representatives, and remote teams who want to manage meetings through chat. It connects with Google Calendar and supports natural-language booking, cancellation, and rescheduling through WhatsApp or Slack. Automatic conflict resolution handles scheduling clashes, while voice-call reminders and meeting briefings add support around the appointment itself. Its chat-first approach suits people who prefer messaging over opening a calendar for every change; it is less suited to buyers who want a free plan or calendar options beyond Google Calendar.
The monthly plans scale by call allowance and team features. Starter costs $22 per month and includes 100 calls per month, a browser extension, Slack, Google Calendar sync, Notion, and WhatsApp. Pro is $29 per month for 250 calls, voice calls and WhatsApp, advanced calendar sync, 90 days of history, and priority support. Team costs $85 per month and includes 1,000 calls, up to 10 team members, team analytics, shared calendars, and an admin dashboard. The listed call allowances are not stated meeting limits. Syder offers a seven-day trial but no free plan, so buyers should consider the monthly allowance against their expected use.
The integrations make Syder a fit for workflows already involving Google Calendar, Slack, WhatsApp, or Notion. The MCP server also supports calendar actions from supported developer environments, while voice reminders and briefings broaden the product beyond booking alone. Its stated calendar support centers on Google Calendar, and the service is delivered on the web. Choose Syder if messaging-based scheduling, rescheduling, and reminders are priorities; look elsewhere if a free ongoing tier or a broader stated calendar ecosystem is essential.
