User Reviews

MarginNote 4 is a powerful study tool with strong PDF processing, side-by-side views, and rich, linked notes and mind maps. Reviewers praise its depth and call it indispensable for study. However, repeated issues curb enthusiasm: unreliable iCloud syncing and occasional data loss; a cluttered UI with a steep learning curve and hard-to-find basic features; frequent crashes; inconsistent support with intrusive purchase prompts; and unreliable AI features. Overall, users value the feature set, but reliability and usability concerns dominate sentiment.

Pros

Excellent PDF processing and analysis that outperforms many readers
Side-by-side view and the ability to move sections into their own tabs for focused study
Rich note-taking capabilities with linked notes, images, and mind maps
Indispensable study tool for many users despite flaws
Expanded options and features compared to earlier versions

Cons

iCloud/Sync across devices is unreliable or inconsistent
Cumbersome UI and a steep learning curve with basic features hard to find
Missing or broken core features (e.g., deleting pages, exporting pages) and occasional data loss
Support and refunds issues, including frequent prompts and slow responses
AI features often fail or are unreliable

卡片分组看版请在过滤中不要默认全选或至少加一个全部反选，否则项目过多只要其中1个很麻烦。再有搜索卡片点击显示所在脑图都须排列縮放至合適大小，能不能直接显示不要调整。还有卡片手写时难免手触碰屏幕，能否不让卡片来回划动甚至手写一半划到别张卡片。

Not supporting an app that undoubtedly shares everything I do in it with the CCCP.

我大量扫描pdf用，用了几年，到现在都是只能担任阅读器适用，最近一个大类别阅读了七八本书籍，准备把摘录笔记整理到一起，笔记摘录希望按目录排序然后导出，这么简单的功能都没有，摘录完乱七八糟堆在一起，连自动整理功能都没有。更新一些乱七八糟的功能一点用没有，主打的笔记功能做的糟糕的要死，开发者你们软件自己用不用？
