About BJJ OS - Brazilian Jiu Jitsu
Transform your jiu-jitsu training with a coaching partner that remembers your entire journey. YOUR TRAINING PARTNER THAT NEVER FORGETS Professor OS remembers every technique you're working on, every challenge you face, and every goal you set. Ask about any position, any situation, any problem — and get coaching tailored to YOUR game. Stuck on a technique? Ask. Want to know what to focus on this week? Ask. Forgot that sweep detail from last month? Professor OS remembers. 6,000+ VIDEOS. ORGANIZED. ANALYZED. READY. Stop wasting hours scrolling YouTube hoping to find quality instruction. BJJ OS gives you the largest organized library of analyzed jiu-jitsu videos ever built. Every video is from a world-class black belt instructor — world champions, Pan American champions, ADCC medalists, and elite coaches from the best academies in the world. New techniques added daily. Every single video is broken down with: - Key concepts and step-by-step details - Instructor tips pulled directly from the video - Common mistakes to avoid - Difficulty level and prerequisites - Related techniques to study next Browse by position — Fundamentals, Guard Play, Passing, Sweeps, Back Attacks, Leg Locks, Submissions, Transitions, and more. Or search any technique and find exactly what you need in seconds. Read a full breakdown in 30 seconds instead of watching a 20-minute video. SAVE WHAT MATTERS Build your personal library. Save any video or technique and organize it your way. That guard pass you drilled last Tuesday? One tap to find it again. TRACK EVERY SESSION Log your training with one tap. Track what you drilled, how many rolls, submissions, taps, and how you felt on the mat. Gi or No-Gi. Class, open mat, comp, or private. Watch your patterns emerge with streaks, calendars, and session history. Professor OS connects the dots — what you trained last week shapes what it recommends next.
