01How it works

From rolling footage to a drill plan.

  1. 01

    Film

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

    Roll 03 · 06:00 · single angle

  2. 02

    Analyze

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

    47 exchanges · 12 positions read

  3. 03

    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

  4. 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

Progress tracking

Watch your guard retention and finish rate climb, roll over roll.

Cross-training ready

In your pocket

The film review most hobbyists never get, the second you step off the mat.

04Questions
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.

When can I use it?

DARCE is in private beta and we are onboarding 50 founding testers first. Join the waitlist and you will get the launch email the moment it opens.
