Pillar OS is cloud-based tutoring management software for tutoring centres, academies, test-prep studios and independent tutors. It brings student and tutor records, scheduling, attendance, billing, payments and family communication into one system. Families use a branded portal to book sessions, make payments, message staff and follow schedules and progress. Scheduling supports individual, group and recurring lessons, tutor matching, availability checks and payroll-hour tracking. Billing handles packages, monthly plans, session credits and card or offline payments. AI-assisted reports use tutor notes; courses, materials and homework support between-session learning. Native two-way GoHighLevel sync and integrations with Stripe, Zoom, Teams, Meet and OpenAI extend the platform. Monthly fees scale by active students; SMS, storage and AI usage cost extra.
