PaperTube is a handy video production tool that allows you to produce videos quickly with a blank notebook. 

This app is capable of recording real-time screen and handwritten data at the same time. It is also a powerful tool for creating videos from a combination of various themes, thoughts, and knowledge.

You can record your video with the theme you want, and it can also be edited and shared with other people.

The best part of this app is that it can be used as a blank notebook for all the contents, including the theme, thoughts, and knowledge. It will help you to create and share various video contents.

You can use a blank notebook or create your own template by using your own formats as background. Your own template can be printed with Ncode A4 paper using the blueprint function.
