5★Great way to get a video game synopsis, have metaphors in a movie plot explained. Can choose length of podcast that gets created. Max length is only 20 minutes unfortunately, and the app doesn't remember where you were last so you have to remember where you were last. These are the only 2 negatives I can think of. Great for car rides, entertainment while mowing the lawn or really anything mundane.

5★If the only feature was the podcast-like reviewing, it would still be worth it. I'm blown away by the genuine richness of that feature. My only wish is that there was some kind of "word processor" where you could write directly in the notebook - even if it was just a simple notepad thing. But I understand that's not the purpose. Overall very cool.

4★The idea is brilliant, but the app itself needs improvements, when adding sources or generating any quiz/flashcards you should be able to rename them too, so you can differentiate which source is what, and the generated quiz is based on what source. Also, when uploading multiple sources, and unchecking one source it shouldn’t include it in the generated quiz, but it still includes whatever you check or uncheck. Good job guys, and I will be more than happy to help you review/improve when needed.

4★This app is really useful for studying key concepts. I really like this app, especially since I can pull it out of my pocket. However, they don't accept PowerPoint, which is kinda disappointing, especially if it's just a Word document. Also, sometimes there are some bugs when trying a slide deck and graphics, but they don't work. Overall, I like this app, and I hope they add support for things I like, such as PowerPoint.

2★It's getting there, but it's nothing special right now. The fact that every single thing needs added as it's own "source" is ridiculous. No groups or subfolders. I get it, it's because they only allow so many "sources" based on what tier you pay for.. But it makes it pretty useless for extensive research. The Featured Notebooks that we can't turn off make me feel like I'm using Bing and being force fed news articles I don't care about. This isn't a notebook so much as an unorganized list.
