【 Key Features 】

Smart, instant, and memorable! Simply enter any Japanese word, and our AI will automatically generate its reading (kana), precise definitions, and contextual example sentences with translations. It also creates custom "AI Memory Hints" (Mnemonics) to help your brain build associations, making vocabulary stick for good.

Flippon integrates the open-source JMdict dictionary and the extensive Tatoeba example sentence database. Query words, parts of speech, and translations offline anytime without using any mobile data. Perfect for airplane rides, commuting, or traveling abroad.

Using the scientific SM-2 Spaced Repetition Algorithm, Flippon schedules review sessions based on your word proficiency (0-5 scale). By prompting you to review right before your brain forgets, it guarantees maximum retention with minimum effort.

Get instant access to official vocabulary packs curated for JLPT N5, N4, N3, N2, and N1. Free users can preview the packs, while Pro users can unlock the entire database, download it locally, and copy words to custom decks for personalization.
