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