Everything Coach Harvey does
One focused coaching directive per swing, frame-by-frame telemetry, a 24-fault detection library, session memory, and the full reasoning of Claude — all in your browser.
One focused fix per swing
After every upload, Claude returns the single highest-leverage thing to work on — not a wall of every flaw. The same call a good human coach would make.
Frame-by-frame swing data
Pose keypoints across every phase of the swing — address, takeaway, top, transition, impact, follow-through. Every metric is visible, not hidden behind a score.
24 swing faults Coach Harvey can spot
From over the top to early extension to head movement, Coach Harvey is trained to detect 24 of the most common faults — and tell you which one matters most for your swing right now.
Browse the library →Every swing you've ever logged
Coach Harvey remembers the last directive, the last drill, and the last time you did the same thing. Your next coaching call always knows what came before.
Long-term swing trends
Once you've logged a few sessions, Coach Harvey starts surfacing patterns — the same fault returning under pressure, a tempo that drifts late in the round, the drill that actually moved the needle.
Drills that target your fault
Every directive comes with practice drills wired to the exact fault Coach Harvey detected. No generic plans, no hour-long routines — just what you need to fix the thing in front of you.
Frontier reasoning, not a chatbot
Coach Harvey runs on Claude (Anthropic). Reasoning quality matters more than speed when the output is something you're about to take to the range.
