About MatNotes: Jiu-Jitsu
MatNotes is how a jiu-jitsu academy makes the details from class actually stick. Coaches film a technique right after teaching it. Sixty to ninety seconds, phone propped on the mat. Students get it that night, then again on a spaced schedule (day 1, 3, 7, and 21), the same rhythm your memory needs to hold onto something new. Instead of "I saw that grip once and forgot it," the move keeps coming back until it is theirs. FOR STUDENTS - A simple checklist of what to review, not an endless feed - Watch tonight, then again each time the app brings it back - Slow any video to half speed and loop the exact section you are stuck on - Tap a moment in a video to ask your coach a question, with the timestamp attached - Keep private training notes and track the techniques you have drilled FOR COACHES - Film once, and the app resurfaces it for every student on the right days - See your students' questions, with the exact video moment, before class starts, so you know what to clean up - Spot where the room got lost on a technique and reteach it - Everything you have filmed, captioned and searchable by position, in one place - Your academy's name and colors throughout MatNotes is used by a whole academy under one plan. Coaches set up and manage their gym on the MatNotes website. Students join with a link from their coach and use the app for free. Questions? Visit thematnotes.com
