工具介绍
点名、抽奖、分任务，最怕抽到谁都被说「你上次也是这个」；随机数抽一次，比拍脑袋公平得多。 Roll call, giveaways and task assignment all suffer from "you picked them last time"; one random draw is far fairer than deciding on the spot.
名单一次粘好，抽几个、允不允许重复都能调，抽完把最近五次留在旁边，回头看谁上过台一目了然。 Paste the list once, set how many to draw and whether repeats are allowed, then the last five draws stay beside it so you can see who already went.

常见问题
名单怎么分隔？How is the list separated?
换行就行，也可以用逗号、顿号、分号；重复的名字只保留一个。Line breaks work, and so do commas or semicolons; duplicate names are kept once.
不想让同一个人被抽两次怎么办？How do I avoid picking the same person twice?
保持「允许重复」不勾选即可，一次抽取里不会有重复；抽的个数超过名单人数时会自动放开。Leave allow-repeats unchecked and one draw never repeats; asking for more names than the list holds turns it on automatically.
能按权重或分组抽吗？Can it weight or group names?
不能，本工具是等概率随机；要分组请分几次贴不同名单。No, every name has equal chance here; for groups, paste separate lists in different rounds.
历史记录会保存吗？Is history saved?
只留在当前页面，刷新就清空，也不会写进本地存储。It stays in this page only, clears on refresh and is never written to local storage.
