I’m the developer of MyStudyDen, a study app for iPhone, iPad, and Android.

The problem I’m working on is the gap between saving course material and actually knowing what to study next. A folder of notes can be organized without being particularly useful for revision.

In MyStudyDen, you add notes or a text-based PDF to a course and generate a study packet: a summary, review questions, and suggested next actions. You can link tasks to that packet and see upcoming work in the Plan tab, so the material and the work you need to do with it stay connected.

There’s also Ask, which answers questions using your saved study packets and shows the sources it used. It’s meant for following up on your course material, not replacing your textbook or doing the practice for you. AI answers still need checking.

One deliberate choice: your study workspace is stored on your device by default. AI requests send the selected material and relevant context for processing, so this isn’t an entirely offline AI app.

AI uses pay-as-you-go credits called Eggs rather than a subscription. New accounts get 30 to try it, and you can see the credit cost before paid actions.

If you already use ChatGPT or NotebookLM alongside a planner, which part of your workflow would you still need to do outside an app like this? That’s the feedback I’d find most useful.
