SwimAI: Swim Coach & Analysis

Film one swim. Kai reads your stroke frame by frame, scores it, and builds your week around what he sees — then watches your watch while you train.

Most swim apps count your laps. SwimAI watches you swim.

Film any swim — from the deck, in any pool. Kai, your AI coach, reads your stroke frame by frame: catch, pull, breathing, body position. You get a technique score, the two faults that matter most, and a plain-English explanation of why they cost you speed.

Then Kai builds your training week around exactly that.

YOUR WEEK, BUILT FOR YOU • A real weekly plan — warm-ups, drills, main sets, cool-downs — built from your technique, your level, and your goals • Every drill has a video and a how-to • Sessions land on your Apple Watch: reps advance on wall touches, hands-free • Miss a week? The plan adapts. No guilt, just adjustment.

DURING THE SWIM • Live heart-rate zones on your watch, your lock screen, and your phone — one glance, same numbers everywhere • Rest countdowns, rep tracking, and pace as you swim • Your phone mirrors the wrist session — coach from the deck

AFTER THE SWIM • Records: fastest 100, longest swim, best SWOLF, best week • Trends no other platform can draw: your technique score charted against your pace and heart rate, week by week • Heart-rate recovery after every effort — the fitness signal serious swimmers watch • Stroke mix, split evenness, and every number Kai reads — you see what your coach sees, always
