It works by breaking the code into flash cards and allow you to add an explanation for each method. This is not for documenting the code but for learning. The best way to learn something is to try to explain it and then fill the gaps in your knowledge ( Feynman Technique). By dividing it on flash cards you can also follow your learning progress.
It also uses spaced repetition to remember what you learned.
It works only in Python now and is just a prototype. My goal is to open source it, so if anyone is interested in helping please ping me ( it's written in Python ).
You can run the prototype here:
