Our take
Pick Knowt if you're students who will stay on Free for unlimited sets and only buy Ultra when they need more than one AI summary a month. Pick WaniKani if you're japanese learners who will do reviews every day. Skip WaniKani if you're people who want a conversation AI (Langua) or a general flashcard app they fill themselves (Anki).
