SubBinder Leave Planner

A web app that turns a teacher’s existing LMS content (Google Classroom/Canvas/Schoology) plus a lightweight pacing template into a day-by-day substitute-ready plan with printable packets, links, answer keys, and a simple classroom routine sheet. It generates a “Sub Binder” (PDF + shared drive folder) and a tracked checklist so teachers and admins can see what’s ready without endless emailing.

Target customer

K-12 schools/districts (principals, instructional coaches, department chairs) that frequently manage long-term teacher absences and long-term substitute placements.

Problem-solution fit

Schools need continuity plans during extended absences, but current processes are manual, last-minute, and disproportionately stressful for teachers—especially during medical leave. This product standardizes the workflow and automates packaging/printing from existing materials, reducing hours of prep and giving admins visibility while respecting teacher constraints.
