MixMyClass is a free random group generator for teachers that remembers past groups, so students get new partners every lesson.
Most group generators forget last lesson, so the same pairs keep coming back. MixMyClass keeps every saved mix and steers students towards people they haven't worked with yet, and away from the table they sat at last time. It shows how many repeat pairs each mix has.
In a hurry? Paste your class list on the homepage and get groups in seconds, with no setup and no account. For regular use, save your class and get seating rules (keep apart, keep together, lock to a table, maximum group size), attendance in one tap, a fair student picker, a projector mode with a countdown reveal, and classroom themes.
Privacy first: student names are stored in the teacher's browser on their own device, with optional sync to the teacher's own Google Drive. There is no MixMyClass server holding class lists, and no ads or tracking.
