Syncline is an AI-first scheduling API that automatically finds and books the best meeting time—no slots, no back-and-forth. Built for developers and AI agents, it uses context, preferences, and calendars to make smart scheduling decisions end-to-end. Perfect for autonomous workflows, assistants, and modern products that want scheduling without UX friction.

Hey Product Hunt 👋 - thanks for being here! What really pushed me to build Syncline wasn’t just scheduling in general, it was scheduling among multiple people who have already agreed to meet. At that point, the intent is there, yet we still waste time comparing slots, negotiating times, and coordinating across calendars and time zones. That friction makes no sense. So instead of asking humans to choose, Syncline lets AI decide. It evaluates 100+ signals - availability, preferences, meeting context, time zones, and historical behavior — to automatically pick the optimal time. And it doesn’t stop there: Syncline learns over time, continuously adapting to individual and group preferences through a self-learning (reinforcement-style) approach. This launch reflects that belief: scheduling should be autonomous once everyone opts in. Would love to hear what you think, and where you’d want to see autonomous scheduling used next 🚀
