Analyze webpage reading difficulty by comparing vocabulary against known word lists 让每一篇英文文章都成为你的课堂——专注阅读本身，而不是翻译动作。 基于 ReadN 设计理念打造的浏览器插件，将任何网页瞬间变为零干扰英语学习环境： 🔹 智能高亮陌生词 —— 自动标注你可能不认识的单词，阅读时心中有数，眼不离行； 🔹 悬停即译 + 点击听发音 —— 半秒获取释义与真人发音，不中断思路，不离开页面； 🔹 从“被动翻译”到“主动习得” —— 不再为查词打断思考节奏，把浏览新闻、论文、小说变成自然、高效的语言沉浸体验。 ReadN = 读英文，学英语，而非翻译英语。
