This study helper app was the only app that I found the most useful to help me study.
This simple web app allows you to upload any files/images and have AI create sample questions to better prepare you for exams. You can even upload your professor's notes and it will generate relevant exam questions that will be written in a way that is similar to your professor's questions. It will also find the most important topics to test you on (even if the professor has a slide deck of 200 pages), so that you can come prepared for your tests/exams!
(Note: It may take a few minutes to load the first time because the server spins down after inactivity. However, I chose to deploy it on Render because it is free and easy to use, and I wanted to make it accessible to everyone without any cost. After the initial load, it should run smoothly.)
