DukeOS for nutritionists and dietitians · AI operating systemCRM, ERP and AI agents in one system. From $49 a month per business. About DukeOS
Dietitian softwareMeal plans, check-ins and steady progress.
DukeOS is the AI operating system for dietitians and nutritionists: meal plans, check-ins, packages and WhatsApp in one app, with Duke, an AI assistant that prepares the work for your approval. Consultations, follow-ups, meal plans and progress in one place. Clients send their weekly check-in on WhatsApp, and Duke adds it to their record so you see the trend before the next session.

01Duke at your nutrition practice
Duke logs every check-in, so sessions start informed.
Clients send their weekly weight and how the week went on WhatsApp, and Duke adds it to their Progress check-ins page. Before a follow-up it sums up the trend, and it drafts renewal notes for programmes ending soon, ready for your approval.
