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.
