Built a free tool site to help my brother study — now has 100+ tools, would love feedback My brother's in high school and needed something more visual to study chemistry, physics, and math, so I used Claude to build him a simple site with interactive calculators and visualizers. I'm not a programmer or from a tech background, so without AI this wouldn't have happened, at least not this fast. It ended up helping him a lot more than I expected, so I kept expanding it, added a bunch of other
观看动画演示微积分问题的逐步求解（导数、积分、极限）。

做了一个会把微积分解题过程“动起来”的计算器，想听听大家的意见 最近做了一个微积分学习工具 CalculusMate 。 起因是我发现很多计算器只给最终答案，即使列出步骤，也很难看出表达式究竟是怎样一步步变化的。所以我尝试把求导、积分和极限的计算过程做成可以逐步播放的形式。 目前支持： - 导数、积分和极限计算 - 展示每一步使用的规则 - 动画演示表达式的变化 - 支持常见数学符号键盘 - 中英文界面 - 基础计算无需注册 可以从这个页面体验： https://calculusmate.com/step-by-step 免费版本： https://calculusmate.com/free 目前还处于早期阶段，我比较想知道： 1. 解题步骤是否足够容易理解？ 2. 动画是帮助理解，还是会让页面显得太复杂？ 3. 还希望优先支持哪些题型？ 欢迎直接指出问题，尤其是计算结果、移动端体验和表达不清楚的地方。
