Agentic Scheduling = Apple Calendar + Apple Reminders + Claude Agent

Agentic Scheduling, a self-hostable scheduling platform from developer hunterZh37, integrates Apple Calendar, Apple Reminders, and a Claude agent to sync Google and Outlook calendars, offer a booking page with only open slots, and allow control via web or WhatsApp. The system merges free/busy from multiple accounts, revalidates availability at booking time, and sends reminders via email and WhatsApp, with a Chrome extension overlaying real availability on Calendly pages.

It syncs your Google and Outlook calendars, gives visitors a booking page that shows only your open slots, and puts a Claude agent in charge, controllable from the web or WhatsApp. Demo: a visitor asks the assistant for open times, then the Chrome extension overlays your own free/busy on someone else's Calendly page. full-quality video The public booking page. Visitors pick a length and a day. Picking a day opens the open times. Every slot shown is genuinely free across all connected calendars. The same page, agent mode. Visitors ask in plain language and the assistant answers from live availability. It can also book the chosen slot. The Chrome extension on someone else's Calendly page Calendly's public demo .

A booking page that only offers real openings. An agent continuously checks your merged calendars for open slots. Availability is revalidated at booking time, so a slot that was just taken cannot be double-booked. WhatsApp direct communication. Text the agent to create, move, or cancel events, check availability, or set reminders. New bookings, cancellations, and reschedules are pushed to you on WhatsApp and email the moment they happen. Reminder emails and WhatsApp reminders. Attendees and the owner get meeting reminders over email and approved WhatsApp templates. A claim/dead-letter worker retries failed sends instead of dropping them. Ask-the-assistant on the booking page. Visitors can chat with a public agent to find a time. It is handed exactly two scope-fenced tools. The private tools are never constructed for it, so safety comes from architecture, not from prompts. Daily morning brief. A DST-safe WhatsApp summary of the day's meetings and tasks. Self-serve reschedule and cancel. Every confirmation carries a signed link the attendee can use without an account. Chrome extension.
