ShuttleAI - AI Badminton Coach

"Practice without a plan, and it ends without a point."

Why not add a personal AI coach to your badminton practice?

ShuttleAI is an AI badminton coaching app that supports your entire improvement cycle — from logging your practice sessions to swing form analysis, rally tactics analysis, and daily practice menu suggestions.

■ Perfect for you if...

You're practicing, but don't know what to fix
You never get objective feedback on your form
You want to review your club or team rallies more tactically
You're too busy (or it's too expensive) to hire a coach
■ What ShuttleAI can do

Practice Log + AI Feedback
Just record the date, duration, content, and how you felt. Based on your goals and past practice history, the AI gives specific advice on what went well, what to work on next, and what to focus on next time.

Video Form Analysis
Just select a video of your smash, clear, or drop — the AI analyzes your form and gives friendly, easy-to-understand feedback based on joint angles. Videos stay on your device and are never uploaded to a server, so your privacy is protected.

AI Practice Menu Suggestions
Based on your profile, goals, and recent practice logs, the AI automatically builds "today's practice menu" — complete with time allocation for each phase and coach notes, ready to take straight to the court.

Rally Video Tactics Analysis
The AI analyzes your full rally footage and coaches you on tactical patterns, shot placement tendencies, and areas to improve — for players aiming to take their game to the next level.

Practice Calendar & Goal Tracking
Visualize your practice days on a calendar. Set a goal, and your practice count and points automatically build up — keeping you motivated with a real sense of leveling up.
