Works for classrooms, workshops, and events
Start with a simple random split. When you need more control, GroupMixer grows with you.
Classroom groups
Teachers paste a student roster and create balanced groups in seconds. No learning curve.
Workshop breakout rooms
Split participants into breakout rooms for a single session or rotate across multiple rounds.
Speed networking
Generate multiple rounds where people meet new faces each time. Minimize repeat pairings automatically.
Team projects
Divide a class or team into project groups. Optionally balance by skill, role, or department.
Conference sessions
Assign attendees to parallel tracks or discussion tables while respecting constraints.
Social mixers
Plan icebreaker rounds where everyone meets someone new. Keep certain people together or apart.
Need more control?
GroupMixer is more than a random shuffler. When simple groups aren't enough, unlock advanced rules without switching tools.
Keep certain people together
Ensure friends, co-workers, or pre-assigned pairs always land in the same group.
Keep certain people apart
Prevent specific people from being grouped together — useful for conflict avoidance or diversity.
Avoid repeat pairings
Run multiple rounds where the same two people don't end up together again.
Balance groups by attribute
Use CSV input to balance groups by role, skill level, gender, department, or any custom column.
The scenario editor gives you full control over sessions, constraints, solver settings, and detailed result analysis.
Guides
Practical playbooks for workshops, classrooms, and repeated group assignments.
How to avoid repeat pairings in workshops
When a workshop has several rounds, a plain randomizer often sends the same people back together. This guide shows how to keep the group mix fresh across rounds and when to use GroupMixer instead of reshuffling by hand.
Read guideHow to run speed networking rounds without repeat conversations
Speed networking works best when participants keep meeting new people each round. This guide shows how to structure rounds, avoid obvious repeat conversations, and use GroupMixer when a plain randomizer is not enough.
Read guideHow to make balanced student groups
Balanced student groups often work better than a fully random split, especially when you want a healthier mix of skill levels, roles, behavior patterns, or social dynamics. This guide shows when balancing helps and how to set it up with GroupMixer.
Read guideRandom groups vs balanced groups vs constrained groups
Not every grouping problem needs the same level of control. This guide explains when a simple random split is enough, when balancing gives better outcomes, and when you should use constraints because logistics or relationships matter more than speed.
Read guideHow to split a class into fair groups
When teachers say they want fair groups, they usually do not mean perfectly random ones. They mean groups that feel workable, balanced enough, and less likely to create the same social or skill imbalance every time. This guide shows how to get there without reorganizing the class by hand.
