四大阅读能力：全文划重点、本页翻译、沉浸式阅读、深度分析；划词内容还能随手存进便利贴。 划重点（XRay Read）是网页智能阅读助手。先帮你判断这页值不值得读，再按你的节奏细读、翻译、划词，并把读过的内容留下来。 四个入口（点右侧浮标即可）： • 全文划重点：在正文顶部生成导读，标出值得停看的段落。 • 本页翻译：整页双语对照，自动跳过广告和横幅。 • 沉浸式阅读：去掉干扰，安静读长文。 • 打开我的便利贴：回到你主动保存的摘录。 划词三件事（可在设置中关闭）： 选中一段文字后，可以做 AI 分析、划词翻译，或存进便利贴。分析与翻译会进入「阅读轨迹」；只有你点「加入我的便利贴」的内容，才会进便利贴库。
