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.

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.

overall good, but organization could be improved. example my notebooks are all in Spanish or Portuguese, but sometimes I accidentally made something with English bc it's the default (can't change). and I can't stop it's production or delete that part without deleting the whole notebook. so now there's useless stuff in the notebook. Also i want to be able to create folders for different notebooks for organization.
