AI BJJ Coach:Analyzeyour rolls.
Film a roll on your phone. DARCE reads every position and exchange, the guard pulls, the passes, the submissions, then gives you a coach’s breakdown and the one position to drill next.
No spam, one launch email when the beta opens.
From rolling footage to a drill plan.

Film
Record a roll on your phone. One fixed angle of live rolling is enough: no rig, no markers, no sensors.

Analyze
DARCE reads the roll position by position: guard pulls, passes, sweeps, back takes and submissions.

Breakdown
See exactly where you lost position and why: the frame you missed, the grip you gave up, the sweep you almost finished.
Weakest: half-guard bottom
- 04
Drill
It hands you the one position to fix next and how to drill it, before the next open mat.
This week: guard frames × 3 rounds
Built like a coach, not a replay.
Technique library
39 BJJ techniques mapped step by step, from fundamental escapes to leg locks, inside a library of 90+.
Weakness detection
Find the position quietly costing you taps before your training partners do.
Personalized drills
A weekly plan built from how you actually roll, not a generic curriculum.
Progress tracking
Watch your guard retention and finish rate climb, roll over roll.
Cross-training ready
The same system reads wrestling and striking, so it keeps up if you cross-train.
In your pocket
The film review most hobbyists never get, the second you step off the mat.
Explore the BJJ technique library
Every breakdown links into a library of named techniques, each mapped step by step.
Can an AI really coach BJJ?
It does not replace your coach or your professor. What it gives you is the film review most hobbyists never get: a clear read on every roll and one position to work on, so your mat time goes further.
What footage do I need?
Just your phone. A single fixed angle of a live roll is enough. No rig, no sensors, no markers.
