Try spotting AI flaws: This AI-written 60s film pitch hides 1 timeline error and 1 generic cliché.免登录试玩挑毛病：下面这段 AI 写的短片脚本藏着「1 处时间穿帮」和「1 句结尾套话」。

In a live class, 50 students auto-group onto the projector in ~2 seconds:在真实课堂上，全班 50 人的选择会在约 2 秒内自动分阵营投上大屏：
ACamp A: The broken timeline ruins the logic.A 派：时间线穿帮是硬伤。
BCamp B: The generic AI cliché ruins the ending.B 派：结尾机器套话最致命。
You joined Camp A! In class, you would now debate Camp B live.你被分进了 A 派！在课上，接下来就是和 B 派当场交锋。

That took 15 seconds—no slide-reading, just active critical thinking.只需 15 秒，不用念 PPT，直接把被动听讲变成主动挑错与思辨。
How does a university class run on loohcs?在 loohcs，一堂大学课怎么上？
We reversed "reading slides in class + copy-pasting AI homework after class" into three clear steps:为什么把 school 倒过来写？因为我们把“课上念课件、台下刷手机、课后抄 AI”反过来改成了清晰三步：
01 · Before Class (15 min): AI Q&A Prep01 · 课前 15 分钟：AI 追问预习
Students preview core concepts 1-on-1 with AI. Asking AI to write the homework directly is blocked—AI only asks guiding questions until they truly get it.学生课前找 AI 一对一过基础概念。想让 AI 直接代写答案？系统自动拦截，只通过反问一步步引导他自己想明白。
02 · In Class (45 min): 50-Phone Live Debate02 · 课中 45 分钟：全班投屏交锋
Everyone answers on their phone anonymously. In ~2 seconds, AI groups 50+ answers into opposing camps on the big screen—quiet students shine without raising a hand.老师抛一个真问题，全班用手机匿名同时作答，约 2 秒自动聚合成正反阵营投上大屏。不用举手点名，社恐学生的好观点照样上墙。
03 · Grading: Score the Process, Not Detectors03 · 课后交作业：看修改过程打分
Students can use AI openly, and earn credit from 4 real proofs: spotting AI errors, adding fieldwork, rewriting clichés, and passing a 60s spot-check.允许大大方方用 AI，拿高分看四件真事：挑出 AI 几处错、补了什么实拍实测素材、改掉哪句套话、能否答上 60 秒随机快问。

Don't outsource your brain to AI—learn to be its director and editor.别把脑子外包给 AI——在这里，学会当 AI 的导演和审稿人。
50 phones submit at once. 2 seconds later, the projector sparks a real debate.全班 50 部手机同时提交，2 秒自动分阵营投屏交锋。
No more awkward silence waiting for volunteers. AI groups all responses in ~2 seconds, projects the sharpest opposing quotes anonymously, and hands the floor back to humans.告别“老师提问、全班低头”的冷场。AI 在约 2 秒内把全班回答归类分派，匿名投出最犀利的正反观点，把主场交还给师生面对面讨论。

Worried students will use AI to ghostwrite homework? The teacher holds the mode switch.担心学生拿 AI 直接糊弄作业？AI 能帮到哪一步，老师一键切换。
Drag the switch below: facing the exact same lazy prompt ("Write the scene for me"), AI enforces completely different rules in each mode.拖动下方开关试试：面对学生同一句“直接帮我写出来”，老师切到不同模式，AI 执行的边界截然不同。
Every mode switch is timestamped.每次切换均自动留痕。
