Weakest: back exposure in scrambles 4. 04 ### Drill It hands you the one position to fix next, like controlling the hips before you enter the legs, or not turning your back in a scramble. Drill next: back escapes ## Built for no-gi, from the feet to the leg locks. Technique library 39 BJJ techniques mapped step by step, including heel hooks, toe holds and kneebars, inside a library of 90+. Weakness detection Find the scramble you keep losing before someone takes your back in it. Personalized drills Fixes from your own no-gi rolls: the position to work on, tied to the moment you lost it. Progress tracking Every roll you upload moves your Fighter IQ, shown against your own average, so you can see if you are climbing. Leg locks included Entanglements and leg lock entries are part of the read, not an afterthought. From the feet Takedowns are part of the BJJ analysis, so the read keeps up when the roll starts standing. ## Explore the BJJ library The library is shared with BJJ and holds gi and no-gi techniques, each mapped step by step. - [BJJ techniques 39 submissions, sweeps, guard passes, escapes and leg locks, mapped step by step.](https://darce.app/techniques/bjj) - [Heel Hook The rotational leg lock that torques the knee.](https://darce.app/techniques/bjj/heel-hook) - [Rear Naked Choke The choke from the back: an arm across the throat, then the squeeze.](https://darce.app/techniques/bjj/rear-naked-choke) ## Key facts about DARCE - DARCE analyses a filmed round of live sparring, read position by position across the whole round, in BJJ, wrestling, striking and MMA, and the same four analyses read sparring in Muay Thai, kickboxing, judo, sambo, no-gi grappling and other martial arts. - The analysis is not limited to a technique list: it names what happens in the round from a vocabulary of 260+ positions, moves and finishes across the four martial arts, while the 90+ technique library is a separate step-by-step reference you can read free on darce.app. - A DARCE breakdown has four parts: a round summary of who controlled the round and where it turned, a position timeline mapped to the second, the key moments that decided it, and up to 3 fixes, each tied to the moment it happened with one line on why. - A breakdown is usually ready one to two minutes after the upload finishes. - Film on your phone from a single fixed angle, in landscape, at about chest height for stand-up and higher, angled down, for rolling; no rig, sensors or markers are needed, and a round of up to 2 minutes can be analysed. - DARCE is a mobile app for iOS and Android with no web or desktop version; it is in private beta, onboarding the first 50 founding testers from the waitlist at darce.app/join, and is not yet publicly downloadable. - DARCE is free for founding testers during the beta, and pricing after the beta has not been announced. ## Other martial arts [All martial arts](https://darce.app/ai-martial-arts-coach) - [AI Wrestling Coach](https://darce.app/ai-wrestling-coach) - [AI Greco-Roman Wrestling Coach](https://darce.app/ai-greco-roman-wrestling-coach) - [AI Judo Coach](https://darce.app/ai-judo-coach) - [AI Sambo Coach](https://darce.app/ai-sambo-coach) ## Questions before you start. [Join Now](https://darce.app/join) **Can an AI really coach no-gi grappling?** It does not replace your coach or the rounds you put in. What it gives you is the film review most grapplers never get: a clear read on your rolls, leg locks and scrambles included, and one position to work on next. **Does DARCE score my rolls like an ADCC referee?** No. It is not a judge. It reads your rolls: positions, passes, sweeps, back takes and leg locks. It keeps no points or advantages under ADCC or any other ruleset. **What footage do I need?** Just your phone. A single fixed angle of a live roll is enough. No rig, no sensors, no markers. **What does it cost?** Founding testers get free access through the beta. Pricing comes later, and early testers will have a say in it.
