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.

/ Coaching directive

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.

/ Telemetry

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.

/ Detection library

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.

/ Session memory

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.

/ Pattern detection

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

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.
