For now, the focus has mostly been on languages, with Japanese in particular due to most of the userbase coming from WK and due to my own goal of learning Japanese. Lately I’ve been working on expanding into other languages and subjects by offering new tools (Russian inputs, upcoming Chinese/Korean dictionaries etc) and eventually want to expand into non-language subjects as well.
Like seanblue mentioned, you can import any anki deck or excelsheet/wordlist (through csv/txt/tsv) into Kitsun and start learning. Since the userbase is also mostly focused on languages, there aren’t many non-language decks in the community centre yet, so sadly that wouldn’t be an option for you yet.
It does not have image-based cloze type of questions, but it does have cards where you have to click/tap on specific spots of images (SVGs). You can find an example of that in one of the Geography decks made by Acm.
@chasekilleen I’m the author so I’m obviously biased, but I initially made Kitsun mostly for my own goal of learning Japanese vocabulary/extra kanji in an easy way, similar in feel to how WK works. It does not have a mnemonic system like WK does, although nothing is stopping anyone from creating such a deck and sharing it with others. The tools currently available (Reader, Subs2Kitsun, Dictionaries) are all aimed at making the process of creating cards while consuming native material, faster and easier.
I personally think that at the point where you learn from native materials, you have enough context that you don’t need mnemonics for vocabulary anymore.
