ShiftCall

by My Teamsupport

ShiftCall is an AI-powered role-playing training simulator for high-turnover industries — call centers, retail, fast food, hospitality, and healthcare support (CNAs, medical assistants). Trainees practice handling difficult customer interactions by speaking or texting with an AI that plays the role of an angry customer, confused patient, or rushed manager. The AI scores responses on empathy, speed, policy adherence, and resolution quality — then generates a coaching report for the human manager.
