Everything you need to run your classroom
Built for teachers who care about fairness, not busywork.
Groups that actually work
High/med/low capability distribution in one click. Every group gets a fair mix — no more putting your weakest students together by accident.
Works on any device, always
Leave school Friday. Pick up Monday. Your class is waiting — nothing to re-enter, no spreadsheets to dig up.
Never rebuild your list
Your roster is saved. Every grouping is saved. Reload any past session or regenerate from the same class in seconds.
No more awkward pairs
Keep anyone separated — or always together. Set "do not group with" and "always group with" per student. The algorithm handles the rest.
From groups to seats in one click
Assign students to physical desks automatically. Multiple layouts. Print for the wall. Your sub walks in knowing exactly where everyone sits.
Put it on the projector
Presentation Mode shows groups fullscreen on your smartboard. Built-in name picker for cold-calling. Timer. Noise monitor. Students never know who's next.
