MarginNote 是给深度阅读者的 PDF 笔记工具。一段摘录同时是 PDF 高亮、脑图节点、闪卡——一次记录三处生效。这是「卡片轴心」架构，让你不必在 PDF 阅读器、笔记 app、闪卡软件之间反复搬运。10 年迭代，18.8 万 App Store 评分。 【四个重点功能】 ▸ 卡片轴心 — 一段摘录三处生效。文档高亮、脑图节点、闪卡，是同一张卡片的三种渲染。 ▸ 标题链接 — 旧笔记在新文档里自动浮现。读到熟悉概念，过去的批注会在页面上自动高亮。 ▸ 留白 — 长按 PDF 任意位置开写作空间。不依附文本，三种显示模式（嵌入 / 页边 / 折叠）。 ▸ 沉浸模式（4.4 新）— 读 / 写 / 忆三态切换。UI 折叠，Recall 模式自动高斯模糊，主动回忆才点击揭示。 【AI 能力（4.2 引入）】 AI 拆书 · AI OCR 模板 · AI 翻译 · AI 问答 · AI 卡片生成 我们的取向是让 AI 作助手而不是替代——每个建议都可以保留为你自己的思考节点，而不是替你思考。 【Apple Intelligence（iOS 26+）】 沉浸 Recall 模式的「学习提示」可在设置里选择走 Apple Intelligence（设备端）或网络 LLM。Apple Intelligence 模式下，三档提示——邻近坐标 / 引导追问 / 关键差异——由 Apple Foundation Models 在你的设备本地生成：不联网、不计入 AI 积分、笔记内容不离开设备。即便你选了网络 LLM，断网时系统也会自动切到 Apple Intelligence 兜底（前提是当前设备支持）——你不会因为飞机、地铁、图书馆里没信号就用不了提示。 【完整工作流配套】 极速 OCR · 学习集（PDF / EPUB / 视频 / 音频）· 直读 Zotero / 网盘 / U 盘 · 10 种思维导图 · 书籍重编 · 双文对照 · 概念图 · 手写图层 【FSRS 间隔复习】 内置 open-spaced-repetition 项目算法（论文已被 ACM SIGKDD 接收，Anki 自 v23.10 起也设为默认调度器）。把短期记忆推向长期。 【适合谁】 对一篇文档要反复读、要建立长期记忆的学习者尤其合用：医学院 · 法学院 · 考研考公 · 科研工作者 · 外语精读 · 严肃阅读。 【全平台】 iPhone + iPad + Mac 同账号，iCloud 同步学习集、笔记、复习进度。Apple Pencil 在 iPad 上原生手写。 — 如有疑问，邮件 service@marginnote.com 使用条款：https://dist.marginnote.cn/MarginNote_Terms_and_Conditions.pdf 隐私政策：https://dist.marginnote.cn/MarginNote_Privacy_Policy.pdf
