@foxysen Anki is definitely *some* amount of work - it varies based on how fast you want to go.

You'd have to do some initial set up, but ideally you spend <20~30 minutes a day reviewing cards. Making new cards is pretty easy if you use a pop-up dictionary like yomichan. If you link your anki deck to yomichan, you'll be able to make and export cards for new words with a single click.

Not a method for everyone but it works for me.

Reading and immersing in content is the fastest way to payoff!
