Brazilian Jiu-Jitsu is a uniquely cerebral martial art. Every opponent is a puzzle. Every roll is a test. Every detail matters. Brain-Jiu-Jitsu is a training companion that helps you train harder and smarter, with tools to track your progress, analyze your performance, and explore techniques through an intuitive Mind Map. ■ MIND MAP See how techniques connect, from Top and Bottom positions down to each related technique. Mastered techniques appear in full color, while techniques you're still practicing stay in grayscale, so you can spot the gaps in your game at a glance. ■ TECHNIQUE LIBRARY Explore techniques by position, watch sample videos, and mark each one as Practicing or Mastered. ■ LOG BOOK Keep your training history, academies, belt promotions, and competition results in one place, including when and where you competed, the event, your opponents, and how you won or lost. ■ ANALYSIS Visualize your mastery rate with charts and see your win and loss trends. ■ AI COACH Ask questions and get coach-style advice based on your own training, strengths, weaknesses, and results. ブラジリアン柔術は、頭を使う格闘技です。すべての対戦相手がパズル。すべてのスパーリングが試練。細部のひとつひとつが勝負を分けます。 Brain-Jiu-Jitsuは、練習の記録、成績の分析、技の整理をひとつにまとめ、「より強く、より賢く」トレーニングするためのアプリです。 ■ マインドマップ Top・Bottomから各関連技まで、技のつながりをマップで表示。習得済みの技はカラー、練習中の技はグレースケールなので、自分の柔術に足りない部分が一目で分かります。 ■ 技ライブラリ ポジション別に技を探し、サンプル動画を見ながら、技ごとに「練習中」「習得済み」を自己評価できます。 ■ ログブック 柔術歴、所属アカデミー、帯の授与履歴、試合記録(日時、場所、大会、対戦相手、勝ち方・負け方)を1か所で管理。 ■ 分析 習得率をグラフで可視化し、勝敗の傾向も確認できます。 ■ AIコーチ あなたの練習状況、得意・不得意、試合結果をもとに、コーチのようにアドバイスします。
