A lot of software make empty promises around productivity improvements. Especially in education. Anki is one of those rare tools that genuinely 10x's you over your peers. I used it when studying Japanese and it was a massive help.
However, having used it for over 12 years to memorise many different things I have noticed one caveat.
If you're not also using what you're memorising outside of Anki, I feel like your ability to recall gets trapped within the context of using Anki.
For example, if you're learning Japanese vocab through Anki, and also trying out your new words via conversation and reading/writing, you'll rapidly learn new vocab AND be able to recall it anywhere.
However if you're learning Japanese on your own and not really conversing/writing, no matter how good your recall with Anki is, you'll struggle to recall those same words anywhere else.
The cool thing about Anki is you can also use pictures/audio. So if you're learning music theory you could memorise chord shapes/intervals. Or human anatomy.
