做了一个 5 Letter Word Finder：按 Wordle 线索快速筛 5 字母单词 最近做了一个英文 5 字母单词查找工具，主要给 Wordle / crossword / Scrabble 这类场景用： https://5letterwordsfinder.org/ 特点： - 可以按 green tile 的固定位置筛选 - 支持 must include / exclude letters - 支持 starts with / ends with / contains pattern - 支持 available letters ，用来做 anagram / rack search - 词库在前端本地跑，结果响应很快，不依赖远程 solver API - 有 common-only 模式，Wordle 场景不会被太多冷僻词淹没 我把工具放在首页第一屏，下面才是说明文档和 FAQ 。现在主要想收集一下文字游戏玩家 / 做工具站朋友的反馈：哪些筛选项、排序逻辑或移动端交互还可以再改？

create multiplayer apps that you can play with friends or share with coworkers. Like Slido/Kahoot but you can create your own one with AI. It can build polls, quizzes or games. had this idea for a while, the space isn't new and there is apps like Kahoot that presenters or educators use for polling/quizzes. however the templates are limited, so I decided to ship my own vibe-coding IDE for generating these. you just describe it for example "noise meter: people scream at their phon
