Octopus Angle
Head on the mat, bottom arm tucked. Pull the knee in to bring your hips high.
Headstand Counter (Jo Chen)
Keep the reach-around grip on the thigh instead of a tight body grip.
Hip Trap Sweep
Trap the hip, come up, and take them backwards.
Darce Threat
It only exists while your elbow is trapped inside.
Elbow Outside Immunity
Elbow outside removes their finishing leverage.
Buggy Angle
Roll back and catch your reach-around arm with your leg.

Arm Throw Escape
They throw the arm over to a cross-body grip.
An example from Craig Jones’ Octopus Guard study map
Part of Craig Jones’ Octopus Guard 2.0 study map: 21 techniques, each linked to the second it’s taught.
Instructionals mapped in the library: Craig Jones, Ryan Hall, Lachlan Giles, Gordon Ryan, Marcelo Garcia, John Danaher, and community maps.
Turn what you learn into a flow.
Start with a video, a photo of your notebook, or a voice recap, and get an editable draft of the techniques and connections. Or open the editor and build the flowchart card by card.
YouTube
Video link
Flow from a YouTube video
Paste a link. Each card keeps the moment the technique starts, so a tap plays the video from the right second.
Jozef Chen · Tripod passing
youtube.com/watch?v=Fjzjk1D4UpM
- Head to the far side. Close the lane through their knee shield.
- Flatten over the hook. Underhook in, head on the far side. Keep their hips flat.
- They fight inside: Hand on the hip, step up. Elbow on their quad, clear the knee, go to mount.
- They frame your knee: Push the knee through. Hips up, then take double unders.
Notebook
Photo of your notes
Flow from a notebook page
Take a photo of a page from your notebook, or up to 8 pages. Your handwriting is read in order, and each sketch on the page is lifted onto the card it belongs to.
Knee cut pass · class notes
1 page with sketches
- Pin and pass. Pin the far hip, sprawl your weight, clear the leg.
- Step over to mount. Keep the far hip pinned.
- They turn away: Take the back. Follow them as they turn.
- Knee cut to north-south. Diagonal pressure, not straight down.
Voice notes
After-class recap
Flow from a voice recap
Talk through the round on the drive home. The draft splits it into techniques and the reactions between them, and builds in the background while you get on with your day.
Closed guard · Tuesday
From closed guard, sit up for the hip bump. If they stay upright, finish the sweep. If they post a hand, switch to the kimura. If they pull the arm free, go for the guillotine. I need to get my hips higher.
- Hip bump from closed guard. Sit up. Get your hips higher than theirs.
- They stay upright: Finish the sweep. Keep the arm controlled.
- They post a hand: Switch to the kimura. Catch the posted wrist.
- They pull the arm free: Go for the guillotine. The neck is there once the arm is out.
Reel link
Flow from an Instagram reel
Share a reel from Instagram. The draft credits the creator and links back to the reel, so the source is one tap away.
Dominique Bell · Single leg X counter
instagram.com/reel/DWFGAD1AQQV
- Clear the foot from your hip. Control the arch and press it away.
- Work around the knee: Post and hop around. Move around their inside knee.
- They post on your knee: Slide in for the armbar. Pull the tricep, slide your knee in, fall back.
Your footage
Video upload
Flow from your footage
Upload a round from open mat and add what you want to fix. Your note stays on the card for the next session.
Passing practice
guard-passing-practice.mp4
My next round: keep the frame collapsed before moving around.
- Start from open guard. Control the distance before passing.
- They play knee shield: Collapse the frame. Keep their legs controlled.
- They sit up: Push them flat. Hand on the shoulder before you move around.
A flowchart canvas for your whole game.
Put down a card for each technique, connect them by what your opponent does, and keep the clip on the card. Building by hand is free on every device.
- A card for every technique. Write the cue and attach the clip. The card keeps the second the technique starts, and its belt colour tells positions, your moves, their reactions and finishes apart.
- Branch on what they do. Drag from one card to the next and name the reaction that sends you there. Every “if they…” gets its own path, so the map reads the way the round goes.
- Saved by position. Save an Instagram reel, a YouTube video, or your own footage, tag the position, and bookmark the moment you want to drill. Before class, it is all in one place.
- Example collection, guard passing: YouTube, Jozef Chen · Tripod passing. 2 bookmarked moments.
- Example collection, guard passing: Instagram reel, Passing the knee shield. Saved from a reel, 1 bookmarked moment.

A few things that won’t change.
Grapple Flows is a passion project for the grappling community.
- Here for the long haul. Thousands of grapplers have mapped their game here since 2019, and the same promises still hold.
- Your data stays yours. We’ve never sold user data, and we don’t run an ad business that depends on it. Your flowcharts belong to you.
- Private by default. Sensitive uploads are encrypted and your data is isolated to your account. Nothing is shared unless you share it.
Questions, answered.
What is Grapple Flows?
Grapple Flows brings your Jiu-Jitsu videos, voice notes, techniques, and training details into one connected system. Build BJJ flowcharts by hand or draft them from videos and voice notes, attach source material and personal cues, and organize your game so you can study it before training.
Is Grapple Flows really free?
Yes. Building by hand is always free: making, saving, and sharing your own flowcharts has been free since 2019. Free also includes 5 Auto Flows a month from notes and 1 Auto Flow a month from a video (YouTube, an Instagram Reel, or your own video). Pro includes up to 300 Auto Flows a month from notes and up to 100 a month from video, longer videos, Enhanced Auto Flow, game-plan reviews, and the Pro Library.
How is this different from a flowchart builder?
The flowchart is the structure for your Jiu-Jitsu study. Grapple Flows also brings in videos and voice recaps, keeps source links and personal notes inside techniques, and groups flows, clips, and photos in collections. You can return to the exact detail and see where it fits in your game, instead of keeping a separate diagram, video folder, and notebook.
Can I edit what Auto Flow drafts?
Yes. Auto Flow creates an editable draft. A draft can miss a detail or misread a transition. Review it against your source, change the techniques and connections, and add your own notes. You stay in control of the finished flow.
Can I turn handwritten notes into a flowchart?
Yes. Take a photo of a page from your notebook, or up to 8 pages at once. Grapple Flows reads the handwriting in order, arrows and indents included, and drafts a flowchart you can edit. Sketches of positions on the page are traced and placed on the cards they belong to. Notebook photos count toward the same monthly Auto Flows as typed and voice notes, on Free and Pro.
What happens to the videos I import?
Auto Flow surfaces the structure of the teaching and always links back to the original source. Your own uploads stay private to your account: encrypted, isolated to you, and never sold.
Does Pro include the original instructional videos?
Pro includes curated study maps of instructionals. It does not include a subscription to the original video platforms or a license to paid instructionals. Sources stay credited and linked; you need your own access to paid videos.
Do I need an account or an app?
You can try the editor without an account. Create a free account to keep your flows across devices. Grapple Flows works in your browser on desktop, iPhone, and Android.
Does it work for no-gi, wrestling, or judo?
Yes. You choose the positions and transitions, so the map can fit BJJ, no-gi, wrestling, judo, or MMA grappling.
Study by position.
Every position page explains the position, what it leads to, and the community flowcharts built on it.
- Closed Guard. Break posture, then armbar, triangle, kimura, or sweep.
- Half Guard. Knee shield and underhook: the sweep-heavy modern bottom game.
- De La Riva. Hook the standing leg and run the modern open guard engine.
- Guard Passing. Pressure and speed passing, from headquarters to the pin.
- Back Control. Seatbelt, hooks, and the highest-percentage finish in the sport.
- Mount. Hold the top pin and open the arm and collar attacks.
- Leg Locks. Heel hooks, knee bars, and ankle locks in one system.
- Takedowns. Singles, doubles, ankle picks, and throws, adapted for BJJ.
