A math PDF extraction engine, built for the internet.

teachyourselfmath

I wished for a free website with an ever-growing list of math problems, teachyourselfmath is that website.

how does it work

If a document containing math problem exists, we'd like to extract every problem from it and dump it in a database. LaTeX is something that can be understood by both, computers and humans. Hence, the problem boils down to converting a PDF into LaTeX, removing the irrelevant parts, and storing the remaining parts.

Meta came up with a model to parse academic PDF documents and find the LaTeX math in it.

Currently, I run this model's server locally on my computer with every PDF I can get my hands on. The main server has a queue-based system that interacts with the model's server and processes all the problems. Here is a visual illustration of how it works:

setup

1. Get nougat from here. Run it as a server.
2. You will need PostgreSQL and Redis to run this.
3. yarn
4. yarn build
5. Setup the .env file using the .env.example file.
6. yarn start!
