Calendly shipped before LLMs existed. Reever is what scheduling looks like now. Three things that don't exist in Calendly, Cal.com, or SavvyCal: (1) configure event types by chatting with it, no settings menus (2) auto-prep brief on every booking that pulls public context plus your own prior emails, Slack, and meeting notes (3) agent-to-agent (A2A) protocol so AI agents can book on your behalf. $9/host/month, undercutting Calendly Standard at $12.
