The free, multilingual encyclopedia of Brazilian Jiu-Jitsu techniques — built with AI, maintained with passion.
BJJ Wiki exists to make Brazilian Jiu-Jitsu knowledge accessible to everyone — regardless of language or budget. We believe that understanding the "why" behind each technique is just as important as drilling it on the mat.
We cover everything from beginner fundamentals like the Closed Guard and Armbar, to advanced concepts like the Berimbolo and Worm Guard.
Each technique includes detailed breakdowns, key details, and common mistakes to avoid.
Curated YouTube videos with timestamp navigation so you can jump directly to the relevant technique.
Every technique is available in English, Japanese (日本語), and Portuguese (Português) — the three global languages of BJJ.
Techniques link to related moves, helping you understand how the game flows from position to submission.
Common questions answered for each technique — great for beginners and intermediate practitioners alike.
No paywalls, no subscriptions. BJJ Wiki is and will always be free to use.
BJJ Wiki is built using a combination of AI-assisted content generation and human curation. Our automated pipeline generates structured, educational content for each technique, which is then organized and cross-linked to create a comprehensive reference resource.
New techniques are added regularly. Our content is reviewed against established BJJ curriculum standards to ensure accuracy and practical usefulness.
