Building a web app that lets me do math and chemistry problems on an infinite canvas with a drawing tablet. After finishing the problem, I can open up an integrated text editor (with vim bindings) that lets me create Anki flashcards about the problem, letting me copy different portions of the handwritten/hand-drawn stuff onto the flashcard.

I developed a very simple compiler to specify flashcard content. Anything inside brackets is considered the "back" of the flashcard (cloze) in Anki. The @n references the nth group in the canvas, and copies those svg paths into the flashcard.

Example card:

  How do you solve for x in this problem?
  @0 // handwritten text of 2x = 4
  
  [ 
  Divide both sides by 2, them simplify
  ]

This project was a response to the lack of systematic review in my college's STEM classes. I would practice a lot, but forget how to approach certain problems on exams. The hope is to have a digital space where I can be reasonably productive in solving practice problems, but also lets me easily integrate with SRS tools.

I wish educators and educational institutions would make an attempt to incorporate SRS into classes. I think it would help a lot of students, especially for cumulative final exams.
