AI Judo Coach
Cleaner entries. Better newaza.
mmaGPT is an AI judo coach app: film a round, upload it and you get timestamped notes on what went wrong and a drill to fix it, to bring to your next class.
Upload uchi-komi, nage-komi or a randori round. mmaGPT checks your off-balancing, your grip fighting, your entries and what you do when the throw does not land.

What to film for judo feedback
Start with 20–60 seconds of familiar uchi-komi, nage-komi or one randori exchange. Keep both athletes, the entry and the landing area in view. Get your partner's permission before recording and upload only footage you have permission to use.
Grip tension and off-balancing can be difficult to judge from one angle. Practise throws with your instructor and suitable mats. AI feedback can be wrong; replay the reported moment and ask your coach about any correction you cannot verify.
Compare judo training apps. For a school, see the Academy video review workflow. Read our footage privacy policy before uploading.

An AI judo coach, on demand.
Judo throws fail for reasons that happen before the throw. If uke is not broken off balance, the strongest uchi-mata in the dojo turns into a lift and a stall. If the grip battle is lost, the entry never gets a chance to start. Seoi-nage entries go wrong in the turn and the depth of the drop, and a beat later the chance is gone. Then there is what happens after: a throw that lands short leaves you in a scramble, and whether that becomes a hold or a lost position depends on how fast you follow into newaza. None of this is easy to feel while you are doing it, and a coach running a full mat cannot watch every rep.
mmaGPT is an AI judo coach that reviews a 20 to 60 second clip of your training. It checks your kuzushi, the timing and structure of the grip battle, the turn and depth of your uchi-mata and seoi-nage entries, and the transition from a landed or failed throw into groundwork. It returns timestamped notes on what went wrong plus a drill to fix it, written for your grade rather than for a national squad. It works alongside your coach, never instead of one: it is a second set of eyes for the uchi-komi you do alone and the randori rounds your coach did not get to watch. Film on your phone, upload in the browser, and bring the drill to your next session.
It works as an AI judo trainer between classes: you film, it reviews, your coach stays in charge.
What mmaGPT coaches in judo.
Kuzushi (off-balancing)
Whether uke is actually broken off balance before your entry starts. Most failed throws are failed kuzushi, not failed technique.
Grip fighting (kumikata)
How you win, keep and break grips, and what your posture does while you do it. The grip battle decides which throws are even available to you.
Uchi-mata and seoi-nage entries
The turn, the depth of the drop, foot placement and where your head and hips finish. Small entry faults turn a throw into a lift.
Transition to newaza
What you do the instant the throw lands or stalls. Following fast into groundwork turns a scramble into a hold instead of a lost position.

How mmaGPT's AI reads your judo.
mmaGPT is judo AI built on computer vision. The model watches your clip frame by frame, tracks body position, balance and timing through each movement, and compares what it sees with how the technique should look for your discipline and skill level. Every correction is pinned to the second it happens, so you can replay the exact moment and check it yourself.
You get one priority fix, the reason it matters and a drill to train it, usually in under a minute. Phone footage works. A side angle with your whole body in frame gives the AI the clearest view.
Built by a world champion.
