Flashcards with spaced repetition. Pick a language and a topic — the tool shows one concept at a time (English → target language) and adjusts the review interval based on how well you knew it. Progress persists in your browser, per (language, topic) pair.
10 topics × 10 languages. Progress is per-cell and persists in your browser.
Cell labels: start = never studied · reviewed/total = studied, none due today · due = cards ready for review.
