Video practice tool JIVX turns any YouTube video's lines into typed or spoken sentences, each one automatically graded. You can paste a video yourself or pick from ones already added. The platform covers many themes — Daily life, Food, Travel, School Work, Anime, manga and games, Culture, and Japanese lessons — with ready-made pages for every JLPT level from N5 down to N1.
Latest practice pages span topics like 【バレたら即終了】背中丸出しでてつやの新居ルームツアーしてみた (Hikakin TV), 【ポッドキャスト】ep.367 アメリカの道路が凸凹すぎる件 (Utaco), 【トヨタが静岡に開業】街まるごと"先端技術の実験場"「ウーブン・シティ」開業日 (NEWSTravel), What Do You See in the Moon? — 【The Moon Rabbit】— Easy Japanese (OYASUMI JAPANESE CHANNEL), 【使うなら今】筋肉モリモリの『メガラグラージ』 (いろは / いろっちゃんねる), 【フィギュア散歩】日本男子最年長・フィギュアスケーター友野一希（28）のオフ (テレビ朝日スポーツ【公式】), and many more. Each page lists sentence counts by level — for instance, Daily life N5 offers as many as 37 sentences, N4 up to 19, and N3 up to 8.
The tool also serves listening practice through podcasts like THAT'S JAPAN | 日本語・文化・日常 and Haru no Nihongo, which provide graded listening materials for intermediate and advanced learners. Whether you are a beginner starting with N5 or an advanced student working toward N1, these practice pages give you structured, line-by-line Japanese input from real YouTube creators.
