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 expert workspace gives you full control over sessions, constraints, solver settings, and detailed result analysis.
