MarginNote 3, all brand new e-reader to better study and digest your books
Integrating powerful tools for book annotation, mindmapping, flashcards and more, to build up your reading notes as never before.
Welcome to MarginNote. This is a highly powerful reading and study software and is applicable to Mac, iPad, and iPhone. By integrating the PDF/EPUB reader and multiple powerful study tools, MarginNote will enable learners to reorganize and connect knowledge from different aspects, then memorize and grasp it accordingly.

Whatever your profession, such as student, educator, researcher, lawyer, or life-long learner, you may annotate and take notes through MarginNote, organize notes via Mindmap and Outline, connect knowledge horizontally via Hashtag and raise memory effect via the Flashcards.

You will discover what MarginNote does is not to simply integrate these tools. Instead, it combines them deeply and skillfully, which makes it easier for users to toggle between different tools.

A great app that could still get better

I’ve used 3 versions of MarginNote over the years, both on my iPads and Macs. A lot has changed, but a lot hasn’t. Each time a new version comes out, I wonder if I want to spend the money and research what else is out there. Maybe I find something interesting and try it, or maybe I don’t, but I always come back. There’s just nothing else that does what MN does.

A lot of the other reviews cover why I look elsewhere from time to time... the app can be inexplicably weird or counter-intuitive or just a little bit off sometimes. I can often get it to do what I need, but not without frustration. Often times, where it fails are in standard UX practices that almost every other app follows, but MN chooses to ignore those and do things its own way.

I’m not a student, so I’m not making flash cards or anything like that, but I do a lot of research. I really like the ability to add multiple documents to one project. I have one with at least a couple of dozen PDFs and epubs, not small ones either, and MN doesn’t complain. There are occasional sync issues, but I’ve gotten good at backing up and—knock on wood—haven’t lost anything yet. I think if you’re only using it one system, that won’t be a factor.

My go-to app now for research, organizing content, summaries

I had used another app ‘fluid’ for reading research articles, underlining and extracting text for summary and study until they crippled this in the free version and increased price for the paid. This app is far beyond that with a superb design for reading, study, organizing spaces, excellent pdf to text extraction and linear or mind mapping ways to relate to the text extractions and your notes both within and between documents. There is a learning curve for use but much is accessible playing around as well. I will be watching videos to learn better use. I have a lot of PDFs stored in Evernote and this app can access and load from within the app. I have used on my my iPhone when my iPad was not available and it’s workable but it is much more useful on a bigger screen. I like it so much that purchased the paid version and might even cough up the larger additional fee for the MacBook version. One of the few apps that is worth the purchase price and more. Excellent!

Excellent concept, but it has some deficiencies

Excellent concept If the app were to work a little more, the tool would be perfect. Unfortunately, it has some deficiencies that, although they could be corrected, can easily cloud the performance of the app and cause a lot of inconvenience to the user. For example, synchronization between devices, iPhone and iPad, is quite problematic. Most of the time it does not synchronize properly, but days after use, and even weeks. Sometimes synchronization never occurs. There are other important faults. TAGS There is no way to create new Tags for the documents (not the notes) in MarginNote 3. ORDER OF THE NOTES. This feature sometimes works, sometimes not, especially, sorting by page order. MOVE. Something as basic as moving a file from one folder to another is torture. Most of the time it is not possible. IMPORT A WEB PAGE This is another torture. Sometimes you can, sometimes not. In short, the developer should work harder.
