You remember the submissions you hit. You forget the ones that caught you. RollBase fixes that.

Log every roll in seconds - submissions, taps, positions, duration. RollBase tracks the patterns you can't see on your own and turns them into a training plan that actually matches your game.

How It Works
Log your rolls after each session. It takes less time than tying your belt.
AI analyzes your data - where you're winning, where you're getting stuck, and what's trending over time.
Get a drill plan built around your weak spots. No generic programs. No guessing what to work on next.
AI Jiu Jitsu Coach
After every session, RollBase tells you exactly what to drill. Your AI coach spots patterns across dozens of rolls that you'd never catch reviewing one session at a time. The more you log, the sharper it gets.

BJJ Technique Library
100+ positions and moves broken down in step-by-step video. Guards, passes, submissions, escapes - isolated and ready to study before you hit the mat. Every technique your drill plan recommends is one tap away.

Track Your Progress
See your submission rate, tap frequency, and position control change over weeks and months. Watch your weak positions shrink and your A-game get sharper with real data behind it.

Built for Every Belt
White belt learning fundamentals? RollBase focuses you on the positions that matter most early on. Brown belt sharpening your game for competition? It finds the 2% gaps you're not seeing. The AI adapts to where you are right now.

Who This Is For
Grapplers who train consistently but don't have a structured plan for improvement.
Competitors who want data behind their game, not just feel.
Coaches who want their students tracking progress between classes.
Anyone tired of showing up to open mat without knowing what to work on.
Stop training blind. Know exactly what to drill before you step on the mat.
