Great product. Have used them for a long time. One of my favorite things about them is that they are able to summarize a whole book into just 10 minutes.

This app has been a lifesaver for my studies. Instead of struggling to finish textbooks, I can quickly get the key points from each chapter. It's helped me improve my grades and understand the material much better.
