Picking a meeting time for six people usually takes forty messages, and Timeful replaces them with one link. Create an event, choose a date range or days of the week, and share the URL; guests do not need an account. Each person drags across a time grid to mark what works, and the combined heatmap reveals the overlap at a glance. Times can be marked as available or only if needed, and a best-times toggle highlights the slots that suit the most people. Calendar autofill pulls busy blocks from Google, Apple, Outlook, or an ICS feed so nobody retypes their week. Time zones convert automatically for distributed teams. Event owners can hide responses from other guests, duplicate polls for recurring meetings, export availability as a CSV, and schedule the final slot straight into a Google Calendar event. Availability groups keep a team's live calendar overlap on a single page, and reminder emails go out to attendees on the day of the event. A plugin API lets browser extensions read and write availability. The interface is a calm green grid with no clutter.
