Kevin Kanji Kraken

So I was looking for WaniKani alternatives (love the concept but $9/mo adds up) and created this site, which is basically a kanji memorizer with Anki style reviews. It uses crowd-sourced stories people spent years writing on a site called Kanji Koohi. The site has a free tier but premium is $5/mo. Curious to see if someone tries it and how does it compare to WaniKani or just using Anki + Koohi?...
