Calendly is a personal assistant tool that allows users to share their schedule with others, eliminating the need for back-and-forth email or phone tag when booking meetings. By sending a link to one's Calendly page, individuals can select available time slots and receive confirmation emails with meeting details. The platform integrates with multiple calendars and popular apps like Gmail and Microsoft Outlook, enabling users to control their meeting schedule and avoid overbooking. Additionally, Calendly offers various meeting types, such as round-robin scheduling and collective coordination, and automates booking processes through integrations with Zapier. By streamlining scheduling, Calendly aims to help users manage their time more efficiently.
