I spend my days interpreting between English and Mandarin: hospitals, 911 dispatch, depositions, banks, insurance. I spend my nights building small tools for the problems I run into there, and for other people who live between two languages.

I am not a trained engineer. I worked through CodePath's Python courses, I build with coding agents, and I am learning JavaScript so I can read what the agent writes instead of trusting it. Most of what I make is a single file that solves one annoying thing properly. If your day job is nothing like software and you assume that rules you out, it does not.

Banks and insurers open every call with a long scripted disclosure, read fast. Interpreters cannot use any tool mid-call, so the only way through is to know those passages cold before the phone rings.

This drills them the way the job actually works. You hear the English with no text on screen. You take notes. You interpret out loud into a recording. Then you reveal the source to find what your notes missed, and the reference rendering to check your accuracy. Playback speed goes above real call speed. Whatever you master leaves the rotation until it is due again.

68 passages   Simplified + Traditional   public federal model forms   nothing from a real call, ever

🌏 Porting it to another language is mostly done for you. The English source text and the practice logic are language neutral. Replace the Chinese field with yours and open an issue so I can link it here.

Every one of these is about the same thing from a different angle: what breaks when people do not share a language.

For: K-12 kids and the parents teaching them Problem: lessons explain once, then move on, and the child forgets by Thursday Animated chalkboard explanations, guided practice, real-world word problems, and AI feedback across Math, English, and Coding. Module 1 of every subject and grade is free forever, no account needed.

For: tutors running 1-on-1 lessons online Problem: you pay for Zoom, plus a whiteboard app, plus a PDF tool, and none of them work on a student's phone The video call, a genuinely clean whiteboard, and your worksheets in one browser tab. Upload any file and write on it. Split view for two documents at once. Students join from any phone and can actually use it.

For: teachers listening to a child read English aloud Problem: you cannot tell whether a misread word is their native language showing through, or something else Transcribes the reading, aligns it word by word against the passage, and flags each substitution as a native-language interference pattern or an inconsistent one worth a closer look. Built for OpenAI Build Week, Education track. It never outputs a risk score, a probability, or anything resembling a diagnosis. That limit is enforced in the code, not just in the prompt.

For: open source projects with Chinese-speaking maintainers or contributors Problem: every AI code review bot writes in English only, so somebody has to translate it A GitHub Action that reviews each pull request and posts the feedback in English, 简体中文, and 繁體中文, with both Chinese sections collapsed so the comment stays short.

白天我做中英口译：医院、911 调度、庭审取证、银行、保险。 晚上我把工作里撞见的问题做成小工具，也做给其他和我一样活在两种语言之间的人。

我不是科班出身。 上完了 CodePath 的 Python 课程，平时用 coding agent 做东西，现在在学 JavaScript，为的是能看懂 agent 写了什么，而不是只能信它。我做的大部分东西就是一个文件，把一件烦人的小事彻底解决掉。 如果你的本职工作和软件毫无关系，因此觉得这件事轮不到自己，其实不是。

银行和保险的电话开头都有一大段固定声明，语速很快。口译时不能使用任何工具，所以唯一的办法是在电话响之前就把这些段落练熟。

这个工具按真实流程练。 听英文，屏幕上不显示原文，因为电话里本来也没有。记笔记。看着笔记用中文口译并录音。最后对照原文，看笔记漏了什么；对照定稿，看译得准不准。朗读语速可以调到比真实通话还快。练熟的段落自动归档，到期才回来。

68 段   简繁双版   取自公开的联邦示范表格   不含任何真实通话内容

🌏 想做别的语种，大部分工作已经替你做完了。 英文原文和练习逻辑与语种无关。西班牙语、越南语、阿拉伯语、俄语、海地克里奥尔语，面对的是一模一样的声明。把中文那一栏换成你的语言就行，做好了开个 issue，我在这里挂上。

这几个是同一件事的不同侧面：人们不共享一种语言时，会坏在哪里。

给谁用： K-12 的孩子，以及在家教他们的家长 解决什么： 一遍讲完就过，孩子周四就忘了 数学、英文、编程三科，用动画黑板讲解、引导式练习、贴近生活的应用题，配 AI 反馈。每个科目每个年级的第一单元永久免费，不用注册。

给谁用： 做线上一对一的老师 解决什么： 要付 Zoom，还要再付白板软件和 PDF 工具，而且学生用手机全都打不开 视频通话、一块真正干净的白板、你的讲义，全在一个网页里。任何格式的文件上传后直接批注。分屏可以同时看两份文档。学生用任何手机浏览器都能进，而且是真的能用。

给谁用： 听孩子朗读英文的老师 解决什么： 一个词读错了，你分不清是母语在起作用，还是别的原因 把朗读转成文字，与原文逐词对齐，再把每一处替换标记为「母语干扰型」还是「无法用母语解释、值得再看一眼」。为 OpenAI Build Week 教育赛道做的。 它不输出任何风险评分、概率或类似诊断的东西。 这条限制写在代码里，不只是写在提示词里。

给谁用： 有中文维护者或贡献者的开源项目 解决什么： AI 代码审查机器人全是纯英文的，总得有人再翻一遍 一个 GitHub Action，每次 pull request 自动审查，并用英文、简体中文、繁体中文三版发出反馈，两个中文版默认折叠，评论不会太长。
