Set your phone down. Swing. Get coached.
Your phone watches for real swings, records them automatically, and scores every phase the moment the club stops. A live coach talks back in your ear — no tripod, no buttons, no re-takes.
- ✓Hands-free capture. Pose detection triggers the record — you just swing.
- ✓Real-time voice coach. Feedback comes through your earbuds between swings.
- ✓Every swing scored. Setup, backswing, downswing, impact, follow-through — all five, every time.
A plan that rewrites itself as your swing changes.
Your training plan isn't a static program. It reads your last ten sessions and picks the drills you actually need this week — then adapts the moment a phase score starts climbing.
- ✓Built from your swings. Not a generic curriculum — drills target your real phase scores.
- ✓Auto-refreshes weekly. Fix one thing, the plan moves to the next.
- ✓Video-backed drills. Each task links to a curated YouTube demo.
Rules, drills, clubs, strategy. It has an answer.
The coach already knows your swing, your misses, and your last scorecard. Ask it anything — from "what's a drop zone" to "what should I practice before Saturday" — and it answers like a coach who's been watching you all season.
- ✓Personalized, not generic. Answers use your phase scores and shot history.
- ✓Upload a scorecard or shot-map. It reads both and tells you where you lost strokes.
- ✓Remembers between sessions. The conversation picks up where you left it.
The only coach graded like a student.
We benchmark our model against a library of professionally-annotated swings and publish the numbers. If we regress, we fix it before it ships.
Pro and coach-narrated clips, 421 ground-truth issues annotated across every phase. Growing toward 1,000+.
Up from 0.18 baseline after the v3 prompt round — measured by an independent LLM judge against expert annotations.
Every model or prompt change runs the full benchmark. If F1 drops, the change doesn't go live.
Read the methodology
Dataset
Swings are sourced from YouTube, Reddit, and GolfWRX — filtered to coach-narrated or instructor-annotated clips so that ground truth exists. Each video is processed by an LLM issue-extractor and then human-verified before joining the benchmark set.
Scoring
For every swing, the model outputs a set of phase-scoped issues. An independent LLM judge compares each predicted issue against the ground-truth set using semantic matching and phase-alignment. We report precision, recall, F1, and a per-phase breakdown.
What we publish
- Full benchmark report on every model/prompt change.
- Per-dimension confusion matrix (setup, backswing, downswing, impact, follow-through).
- Latency and cost per analysis — so we don't trade accuracy for speed silently.
Known limits
Ground-truth quality is currently the ceiling — ~140 GT issues appear only once across the set, and many are vague ("general poor swing quality"). Further F1 gains require cleaner labels, not just a better model.
See the trend, not just the last swing.
Every swing you take is one data point in a line that gets longer week by week. You see which phases are climbing, which are stuck, and what changed since last month — so you know the plan is working.
- ✓Phase scores over time. Charted per phase so you can see where the gains are real.
- ✓"What shifted" notes. The coach summarizes what moved this week and why.
- ✓Personal records. Best round, best session, best impact — tracked automatically.
