錆び錆び is a memoization software that uses Anki collections to allow players to guess what's on the other side of a card by choosing the right one out of the proposed answers.
First of all, export your anki deck to a plain text file through the official client.
A sample command to run 錆び錆び could be $ cargo run front ~/Desktop/kanji.txt.
Press Ctrl + C to quit.
