Every weakness in your game.
Found.
Film practice on your phone. Four minutes later, Baseline reads your tape like a tour coach — what's breaking down, what it costs you in points, and the drills that fix it. Free to start, no credit card required.
How AI tennis coaching works
Three steps from footage to coaching feedback.
Upload your video
Record practice or a match on your phone, any angle. MP4, MOV, or AVI, up to 5 minutes.
The AI reads every stroke
Baseline picks out every shot type, tracks technique patterns across the whole session, and scores your performance in under 4 minutes.
You get real feedback
Scores and specific notes on technique, footwork, and consistency, plus drills you can actually take onto the court the same day.
What your AI tennis coach analyzes
Detailed feedback across every part of your game.
Stroke technique
Forehand, backhand, serve, volley, overhead. The AI looks for faults that repeat across multiple shots, not one-off mistakes.
Movement & footwork
Split-step timing, recovery patterns, court positioning, balance at contact. Footwork is usually the hidden cause behind a technique problem.
Consistency & patterns
Shot reliability, contact point, depth, net clearance — tracked session over session so you can actually see the trend.

Frequently asked questions
About AI tennis coaching and how Baseline works.
What is an AI tennis coach?
It watches your footage the way a coach would, except it doesn't blink and doesn't get bored halfway through your session. It picks up on stroke patterns, footwork habits, and technique faults across the whole video, not just the shot or two a person happens to catch.
How accurate is AI tennis coaching?
Baseline looks for faults that repeat across multiple shots rather than one-off mistakes, and reads shot type, body position, and movement mechanics. It's meant for coaching and training, not a replacement for a real coach if you're playing competitively.
Do I need special equipment?
No, any smartphone camera works. Film from behind the baseline, the side, or a corner angle — a fence mount or tripod helps. You'll note your clothing color at upload so the AI knows which player on court is you.
Can I analyze multiple players?
Yes. Set up separate profiles for yourself, students, or anyone you coach, and each analysis links to the right player so you can watch their improvement over time.
How long does AI tennis analysis take?
Usually 2 to 4 minutes from upload to results, depending on the video and how busy the servers are. You'll see the progress live as it works through each stage.
