BJJCraft: Make Your BJJ System

Build your own BJJ OS — your personal game blueprint.

BJJCraft is an app that helps you turn your BJJ knowledge into a searchable, structured system you can apply and continuously improve.
It was built from real competition and teaching experience by the head instructor of Tokyo Jiujitsu Club, a 2nd-degree BJJ black belt and multiple-time IBJJF champion.

Even when people train the same way, some get stronger and others don't.
The difference isn't talent.
It's how well they organize and operate their own BJJ OS — their personal game system.

Training notes, technique videos, flowcharts.
BJJCraft brings scattered BJJ knowledge together and turns it into a system you can search, use, and continuously build upon — your own BJJ OS (game blueprint).

AI in BJJCraft doesn't give you generic answers.
It works quietly in the background to organize, search, and structure your data, helping you turn what actually works for you into long-term BJJ knowledge assets.

Key Features

■ My Knowledge

Daily training takeaways, videos scattered across social media or your phone, your personal technique flowcharts, and what you're currently focusing on in training.

BJJCraft's organizing groups and AI support connect recording → organization → intention into training that actually makes you stronger.

■ Video & Notes Library

Save techniques you've learned or studied with videos and notes.
Organize them by position or custom groups, so you can instantly find the right technique for the right situation.

■ Flowcharts

Visually organize technique sequences and decision branches.
From positions to next transitions, and responses to your opponent's reactions, build your personal game blueprint step by step.

■ AI Search Assistant

Search your own records using natural language.
Find things like "positions where I get stuck in half guard" or "techniques I've been using a lot recently," directly from your own data.

■ AI Organization Support

Automatically organizes videos, notes, and flowcharts based on your groups.
Keeps your knowledge from becoming cluttered and ensures it stays reusable and practical over time.
