工具介绍
课堂上分组讨论、公司里分任务、团建时分队，最怕分得不均——有人一组五个人，有人一组两个人。 Classroom discussions, work assignments, team games — uneven splits are the usual complaint: one group of five, another of two.
这里按行读名单，选「分几组」或「每组几人」，随机打乱后平均分配。人数不能整除时，前面的组多一人，差距最多一个。 Names are read line by line; pick how many groups or how many per group, and they get shuffled then spread evenly. When the count does not divide, the earlier groups take one extra — a difference of at most one.

常见问题
能保证每次都不同吗？Is every shuffle different?
不能保证绝对不同，但用的是随机洗牌，重分几次基本就换样了。Not guaranteed identical-free, but it is a real shuffle, so a couple of rerolls change the layout.
为什么第一组多一个人？Why does the first group have an extra?
11 人分 3 组无法整除，多的那个会依次落到前面的组，保证差距只有 1。Eleven into three does not divide, so the remainder goes to the earlier groups and the gap stays at one.
能按性别或部门平衡吗？Can it balance by gender or team?
不做条件约束，只能是纯随机；需要平衡就手动微调。No constraints — pure random; adjust by hand if you need balance.
名单会上传吗？Is the list uploaded?
不会，全部在浏览器内存里算。No, it stays in browser memory.
