知识树 vs PixWhat

这不是一款“多做题”的学习 App， 而是一套真正判断你是否学会的智能学习系统。 在这里，AI 不只是出题，而是先理解知识、拆解考点，再根据你的记忆状态动态安排练习与复习。 每一个知识点，都会被拆成清晰、可掌握的最小考点； 每一道题，都会服务于“真正记住”，而不是刷完就忘。 你不需要自己规划复习，也不需要反复猜“我到底学没学会”。 系统会结合你的答题表现与科学的记忆曲线，自动判断哪些内容已经稳定进入长期记忆，哪些还需要巩固。 当一个知识点被标记为“已掌握”， 意味着它已经经过多次间隔验证，而不是一次侥幸答对。 你看到的，不是题量，而是进度； 你追求的，不是速度，而是完成。
