New founder just shipped a project on Small number, but every one is a real person who chose to get honest feedback instead of "looks great". Building this one roast at a time. #buildinpublic

做了一个中小学生作文点评工具,想听听大家的意见 大家好,过去一段时间,我做了一个面向中小学生的中文作文点评网站,叫「红笔作文」。 地址: https://getredpen.cn 1. 为什么做 我发现作文批改有一个很实际的问题: 老师需要面对一个班几十篇作文,很难在每一篇里都写下完整的修改过程。家长想辅导,也常常知道“这里不太好”,却不知道怎样给出具体建议。 另外,老师写的“内容不具体”“结构需要调整”“语言不够生动”通常没有错,但孩子回家后,还是不知道具体是哪一句、为什么有问题、应该怎么改。 所以我想做的不是一个帮孩子生成作文的工具,而是把作文中的问题落到具体段落和句子上,再给出孩子能够理解的修改方向和局部示范。 2. 目前能做什么 用户可以直接拍照上传手写作文,系统会识别正文并生成一份点评报告,包括: - 综合评分和总评 - 内容、结构、语言、规范等维度评价 - 对应原文的逐段批注 - 文章亮点和主要问题 - 可以实际练习的写作技巧 - 局部修改建议和改写示范 目前支持小学三年级到高中三年级。评分时会结合学段、年级、地区和作文类型选择相应参考

Why does feature request software cost so much? I have 2 apps, both without any good customer feedback collection mechanism. My apps are very customer focused, and so I wanted a way to figure out specifically which features to build next for my users. I first looked for existing solutions, but most were $20+/month, or self-hosted and difficult to setup. Many of these tools had tons of cool features which justified the price, but I did not want all of that. I created Simple Feature B
