AI BJJ Coach
AI BJJ Coach
Better positions. Cleaner submissions.
mmaGPT is an AI BJJ coach: upload a roll or drilling clip from your phone browser and it marks the flawed technique with video timestamps, then gives you a drill to fix it. First analysis free, no card needed.
Upload a roll, a drilling clip, or a positional sparring round. The AI grades your guard, your passes, and your submission chains the way a black belt would in private review.
An AI bjj coach, on demand.
BJJ has the steepest learning curve of any martial art in the world. There are roughly a thousand positions, ten thousand transitions between them, and any one of them can collapse on a single posture mistake. A white belt who passes guard with bent posture leaks energy on every pass attempt. A blue belt who never frames before the underhook surrenders the back every roll. These mistakes do not announce themselves, they just show up in your scorecard at competition.
mmaGPT is an AI BJJ coach built to flag the structural mistakes a human coach catches in the first ten seconds of watching you roll. Film a 60-second round, a passing drill, or a positional restart, upload it, and the AI grades posture, framing, weight distribution, grip timing, and submission chains against the position you were in when the clip started. You get one highest-impact correction, the thing that, if you fixed it, would change five other problems downstream, plus a specific drill ladder to take to open mat. It is not a substitute for your professor. It is a way to make every roll a graded rep instead of a guessing game.
It works as an AI BJJ trainer and BJJ AI analysis tool between classes: you film, it reviews, your coach stays in charge.
What we coach in BJJ
The techniques that move the needle.
Guard retention
Frames, hip movement, grip fighting, and the order you give up positions when you lose the guard. Most retention failures happen before the pass, we grade the setup.
Passing fundamentals
Posture, base, the order of grip breaks, knee-cut versus toreando shape selection, and weight distribution at the moment of the pass. Bent passing is the most common mistake, and the most punished.
Sweeps & reversals
Off-balancing direction, grip timing, and whether you actually finished the sweep or just exposed your back chasing it. Sweep efficiency is the silent IBJJF scorecard difference.
Submission chains
Setup → control → finish. A naked submission attempt is a position trade. A submission off a real control is a finish. The AI grades the chain, not just the lock.
How it works
Clip in. Drill out.
Upload your clip
A 20 to 60 second clip of rolls, drilling or positional sparring.
Frame-level analysis
Our analysis engine reads your video, grading technique against your discipline and skill level.
Get a drill ladder
Not just feedback. A specific drill progression you can take to your next session.
Online bjj coaching
An online bjj coach that works around your schedule.
Online BJJ coaching used to mean buying an instructional, watching a black belt do a technique on a compliant partner, and hoping you could replicate it at open mat. That model never closed the loop on your specific roll, the instructional could not see your posture collapse on the third guard pass attempt, your hips lifting in side control escapes, or the framing you keep forgetting before the underhook lands.
mmaGPT closes that loop. Film your roll or your drill, upload from your phone, and the AI grades the positions you actually got into, not the idealized version a black belt drilled on YouTube. Run the drill ladder at the next open mat, film the result, and compare. For jiu-jitsu hobbyists training three nights a week without access to a private with a high black belt, this is the structured review that closes the gap between class and competition.
From beginner to fighter
From your first class to your tenth fight.
Set your belt and the feedback calibrates. A white belt gets coaching weighted toward posture, base, the one-grip rule, and the order positions collapse when defense fails, the fundamentals that, if drilled, prevent five years of bad habits at higher belts. The AI will not throw a Berimbolo at a four-stripe white belt.
A blue belt gets feedback on framing before the underhook, hip movement out of bottom side control, and the first layer of guard retention against passing chains. Purple, brown, and black get pattern-level analysis on the small things their professor already corrects in person, flagged in the rolls their professor was not watching. The grading floor and ceiling both shift with your belt, so an experienced grappler is not insulted by white- belt corrections and a new white belt is not overwhelmed by submission chain theory.
BJJ AI feedback starts with a clear recording
Choose a position you already practise, ask your partner before filming, and keep both athletes visible. Replay each reported timestamp before deciding what to change. Hidden grips and pressure can limit what any video review can establish.
Use the report to choose one question for your professor, then repeat the same positional drill under supervision. See the BJJ training app and compare BJJ apps for instruction, journals and video feedback.
BJJ apps compared
Where each one wins.
BJJ apps do different jobs. This table says what each one does, using only what mmaGPT and the other apps say about themselves.
| App | Where it wins | Price |
|---|---|---|
| mmaGPT | Grades your own rolls and drilling clips: marks the flawed technique with video timestamps and gives a drill, about 30 to 45 seconds. First analysis free. | First analysis free; plans on /pricing |
| BJJ instructional libraries | Technique videos taught by instructors, per their own listings. | See their site |
| BJJ training and tracking apps | Logging sessions, curriculum and notes, per their own listings. | See their site |
They work together: learn the move from an instructor, then upload your roll to see where your version leaks. Bring the notes to your professor.
