Smootables is an AI-powered cloud platform for school year planning and automatic timetabling. Schools model academic years, courses, teachers, rooms, and student groups in one workspace, then generate period timetables with a constraint solver. Pre-generation validation flags missing data and impossible workloads before a solve runs, and typed infeasibility reports explain why a timetable cannot work and what to change. Planners keep control with drag-and-drop editing, pinning, branches, undo, and an AI planner assistant. - School year and multi-year academic planning in one model - Constraint-solver automatic timetable generation (CP-SAT) - 13 pre-generation validation checks before any solve - Typed infeasibility reports with concrete fixes (13 conflict causes) - Always-enforced hard constraints and 6 configurable soft preferences - Waiting area for unplaceable lessons; partial-timetable recovery - Drag-and-drop editing, swap, split, pin, undo/redo

Bildena Scheduler is a browser-based timetabling application for schools, colleges and universities. It builds schedules from classes, students, teachers, subjects and rooms, balancing hard constraints with preferences for availability, double periods, room requirements and gaps. Its Google OR-Tools CP-SAT solver shows progress and checks schedule feasibility. Planners can review results, move lessons and replan affected parts, compare scenarios, and manage substitutions and duty rotas. Data can be entered or imported from spreadsheets and supported timetable files, including aSc TimeTables and Untis exports. Student-based scheduling supports course requests and personal timetables. Pro adds course choices, blocks, personal student schedules, and teacher working-time rules for all 16 German states. Teachers can view schedules in a browser. The interface is available in English, German and French. The service is hosted in German data centres and offers a free trial.
