For most learners MemoCard (@memo_card_bot) is the better pick: it works for any language or subject, while Nihongo Go (@nihongo_go_bot) is built for one goal, Japanese and the JLPT. MemoCard is a spaced-repetition Mini App with unlimited decks, a catalogue of ready-made ones and text-to-speech, but you still write cards yourself or take them from the catalogue; building decks with ChatGPT is a Pro feature at $4 a month. Nihongo Go asks you to build nothing: pick your JLPT level and it sends vocabulary, kanji and grammar cards from N5 to N1 at the pace you set, plus kana speed drills; its interface is English only. If you are studying Japanese and don't want to make decks, choose Nihongo Go.
Flashcards with spaced repetition as a Telegram Mini App: unlimited decks, a catalogue of ready-made ones, streaks and a heatmap, text-to-speech for languages. Open source under MIT, with browser and mobile apps alongside.

A JLPT-oriented Japanese trainer inside Telegram, free to start: vocabulary, kanji and grammar cards from N5 to N1 on your schedule, kana speed drills, quick quizzes and AI explanations on demand.
