The Otter Coach
A structured Brazilian Jiu-Jitsu knowledge base. Every technique, position, belt, and drill is organised the way a coach actually thinks about them — connected, sourced, and signed off by a named reviewer.
Browse by topic
- Techniques — submissions, sweeps, escapes, passes, takedowns, and controls.
- Positions — guards, top positions, standing, and transitions.
- Belts — white, blue, purple, brown, and black, with promotion criteria for IBJJF, Gracie Humaita, and Gracie Barra.
Why this site exists
Most BJJ resources online are either short blog posts written for clicks or video instructionals locked behind paywalls. There is very little in between: structured, accurate, free reference material that respects how the art actually fits together. The Otter Coach is an attempt to build that missing reference layer — a place where every technique links to its parent position, every position links to the techniques that come from it, and every claim is tied to a named source or a named reviewer.
Coaching app
In addition to the reference content, The Otter Coach runs an AI training coach you can talk to via web, mobile, or Telegram. The coach helps you focus your training, run pre-session briefings, and track what you're working on across sessions. Sign up at app.theottercoach.com →
