Title: AI Sparring Analysis: How It Works | DARCE Canonical: https://darce.app/ai-analysis > How DARCE's AI reads your sparring: RTMPose-m tracks 13 joints per athlete, about 15 times a second, and a video AI names the positions and moves in the round. # AI Analysis Two systems watch every round you upload. One tracks your body. One reads the fight. A real sparring round: both athletes' skeletons, from the same pose model DARCE uses, drawn over the footage the way the app draws them, with labels on the tracked joints. ## Two systems. One app. Every round you upload is read twice, by two systems that work apart. Your round ### Limb tracking Follows your body, joint by joint. 13 joints tracked on each athlete 15 pose reads a second on most video Your hand speed across 9 seconds of the round above, 135 pose reads, scaled to its peak.

Scored every Monday An AI judge scores each new striking, wrestling and BJJ version on real rounds, and the whole set runs again every week. Tried and dropped - A cheaper model - A second AI double-checking every breakdown Both tested on real rounds ## Only confident calls get through. The AI drafts each breakdown and rates how sure it is of every call. Code checks each call before you see it. An example round. The AI's draft has four calls: a body lock and a suplex takedown it is sure of, a sweep it rates under 0.5, and an armbar finish it rates between 0.5 and 0.7. Code checks them: the sweep doesn't count, and the finish is logged as an armbar attempt, so your breakdown has the body lock, the suplex takedown and the armbar attempt. A key moment is kept only if it falls within 1 second of something the AI logged in its play by play; one further away is cut. Key moments within **1 s** of the play by play With 3 or more real events you get a full breakdown; with fewer, you're told video quality made automatic analysis unreliable, and what it did find is still there. At least **3** real events for a full breakdown At most 3 fixes, so you know what to drill next. At most **3** fixes, so you know what to drill ## Your numbers build with every round. Fighter IQ is provisional for your first five rounds, then settles as more come in. Fighter IQ settles after **5** rounds Everyone's success rates are anonymous totals, shown only once at least 5 athletes and 20 tries with a clear result stand behind a move. Success rates need **5** athletes and **20** clear tries Anonymous, never one athlete's alone ## What it can't do yet. - Use the skeleton in your breakdown - Reliably see you both when tangled on the ground - Be right every time ## Questions before you start. [Join Now](https://darce.app/join) **How does the AI analysis work?** Upload a round from your phone and DARCE's AI watches it the way a coach would. It reads the round position by position and explains what it saw in plain language, ending with the one position to drill next. **What's in a breakdown?** 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 what to fix, with each fix tied to the moment it happened and one line on why. **Does it tell me what to drill?** Yes. Every breakdown hands you the next technique to drill, so you always know what to work on next. Its fixes are tied to the moments they happened, each with one line on why. **How accurate is the AI?** Like any AI, it can make mistakes. Your breakdown may be inaccurate, incomplete or miss context, so treat it as general information rather than coaching advice, and check anything important with a qualified coach.
