I spent the last year building my first project, looking for some real feedback and opinion. Hello everyone. So last year i had simple idea to make a ChatGPT to pdf website, where user can paste a link and and download the pdf of a certain part of the cha.

最近 Vibe Coding 术语网站 做了一个小更新,之前有用户反馈卡片信息密度太高,比较难找到自己想要的术语。 于是我做了一些小调整,把卡片里原本的吧别名和小标签都移除了,加大了每一个卡片的标题字号,对应的英文术语调成主题色并且也加大字号。 我觉得一个最棒的调整就是将原本用于解释这个术语的描述,直接改为大家可能会去跟 AI 描述的话,比如鼠标的 hover 效果,它的描述: 修改前: “悬停是鼠标指针停在元素上但尚未点击时出现的交互状态” 修改后:“鼠标放上去的时候按钮变个色,让人知道它能点。” 经过这次修改,我自己能感觉到每一个术语在列表页上看都更加直观了,而且第一次访问可能会更有共鸣。 除此以外产品和后端相关的术语我也补充了更好的交互图解,相比干瘪的文字能够更好的让大家快速理解~ 下一步可能会做很棒的 AI 搜索功能了,目前大家如果要更方便的使用可以先用 vibe-hub 的 skill: 这个 Skill 可以让 Agent 获取网站里的任何信息。
