Mr. Jiu Jitsu

Sourced coaching · never invented

Your training partners
tell you what
you want to hear.

So does the AI. Ask it why your guard keeps getting passed and it says drill it more, stay patient — the safe answer, the one that costs you three years.

The coaches who actually solved that position said something specific about it, out loud, on the record. We index what they published. When it is relevant, they interrupt — and you get a link to the exact moment they said it.

Your corner is the handful of coaches you put in your ear — the same way a corner works between rounds. You pick them, only they can interrupt, and you can swap them whenever your game changes.

I keep losing the heel hook when they turn away. What am I missing?

Generic AI

Make sure you maintain control and keep practising the position. Consider drilling it with a partner at reduced intensity.

A corner that talks constantly is just noise.

So most of the time, yours says nothing. Three things have to be true before anyone in your corner is allowed to interrupt an answer.

01

You picked them

Only minds you put in your corner can speak. Nobody is assigned to you, and a mind you remove goes quiet immediately.

02

They actually covered it

The question has to land in a subject they have indexed material on. A leg-lock specialist stays quiet about your takedown problem.

03

They said something specific

A verified passage has to clear a relevance bar. Below it, nothing fires — we would rather stay silent than stretch a quote to fit.

Every decision is logged — including every time the gate stayed quiet, and why. “No spam” is a claim you can audit on your own account, not a line in our marketing.

Ask them directly

Type @ to pull one coach aside.

Most of the time your corner decides when to speak. When you want a specific voice, name them — and you get only what that coach actually published on it.

They step in when it matters

Mostly they say nothing. Then they disagree.

Ask normally and the answer comes back as usual. Your corner only breaks in when someone in it has published something specific that cuts against the safe answer.

Should I just drill more to fix my guard?stepped in

every decision is logged, including the quiet ones

The safe answer is always available. That is the problem.

The plateau

“My guard keeps getting passed by bigger guys. What do I do?”

Generic AI

Focus on hip movement, stay active, and keep drilling your retention.

True, useless, and free everywhere. It does not tell you which frame fails first.

Competition week

“I gas out in the second half of every match. Cardio problem?”

Generic AI

Improve your conditioning with interval training and manage your pace.

Most people who ask this have a grip-tension problem, not a cardio problem.

The injury

“My knee clicks when I play half guard. Should I stop?”

Generic AI

You should consult a medical professional about persistent knee pain.

Correct and unhelpful. Coaches who have coached through this have said more.

The roster

Pick who is in your ear. Swap them whenever your game changes.

  • Nothing is generated in a coach’s name.

    The model picks which passage is relevant and writes the framing around it. It never writes the quote.

  • A human verifies every passage.

    Ingested material sits unpublished until someone checks it against the source. Unverified passages cannot be surfaced by any code path.

  • No endorsement is implied.

    Indexing published material is not a partnership, and we never say it is.
