AI-powered BJJ Journal
Free · In‑App Purchases
Talk through your training the moment you step off the mat. Voice coaching, hands-free journaling, and game plans that build on every session.
Linear BJJ is an AI training journal for Brazilian jiu-jitsu athletes.
Just talk to Linear's AI via voice or chat, talk about rounds, techniques, questions, injuries, and training goals in one place. Linear turns those notes into practical next steps: what to drill, what patterns keep showing up, and where your game needs attention.
Use Linear BJJ to:
- Capture training notes after class or open mat
- Chat with an AI assistant about your game
- Use voice mode when typing is too slow
- Build a scorecard from your training history
- Track progress across journal entries
- Keep your goals, style, and preferences in memory
