About Second Brain Grappling
Your grappling game is bigger than what you can keep in your head. Build a second brain for it. Second Brain Grappling is an AI-powered ecosystem built to help grapplers capture, connect, understand, and develop their game. Build a visual knowledge graph of your positions, techniques, transitions, submissions, escapes, and concepts. Connect everything together and create a living representation of how your game actually works. MAP YOUR GAME Turn your grappling knowledge into an interconnected graph. Start small and keep building as your game develops. FIND THE GAPS See how complete different areas of your game are, discover weak spots, and understand where to focus next. CAPTURE WHAT YOU LEARN Add techniques and concepts as you learn them. The AI-powered ecosystem helps transform your thoughts, training notes, and discoveries into structured knowledge. ANALYZE YOUR ROLLS Use video analysis to break down your grappling and turn what happens on the mats into insights you can actually use. PREPARE WITH BATTLE CARDS Turn your knowledge into actionable Battle Cards built around positions, situations, and problems in your game. BUILT AROUND YOU Your athlete profile, knowledge, strengths, gaps, and preferences work together to create an experience that becomes more personal as your Second Brain grows. Whether you're trying to remember what you learned yesterday or map years of grappling knowledge, Second Brain Grappling gives your game somewhere to live. Build it. Connect it. Evolve it.
