DemandForce is a communication and marketing tool that allows Keith Clinic to send automated appointment reminders, rescheduling options, and other messages to patients via text or email. It integrates with the clinic's patient management system to access appointment information. DemandForce keeps records of all patient interactions and aims to improve efficiency of communication with patients at scale. However, some criticisms of it include that the visual design is not very appealing and it does not allow direct scheduling through the platform.
