What it is
The Diagnostic Engine is the brain of SwingVantage. Instead of dumping a wall of numbers on you, it reads your shot data, video, or logged session and answers the only question that matters for getting better: "What is the one thing holding me back right now, and what do I do about it?"
Available checks depend on your sport, motion and evidence. Video readings are estimates; imported and entered values retain their stated source. A supported finding can guide a practice focus, but a score or a symptom alone does not establish a confirmed mechanical cause or prove improvement.
Crucially, the engine is transparent. Each finding shows the exact evidence behind it, the most likely causes, and an honest forecast of what changes if you correct it — so you can agree or disagree with the diagnosis rather than taking it on faith.
Who it’s for
- Players who get overwhelmed by raw launch-monitor or video data and want a clear next step
- Anyone practicing without a coach who needs an objective second opinion
- Self-coached athletes who want to work on the highest-leverage fault first
How to take full advantage
A step-by-step guide to getting everything out of AI Diagnostic Engine.
- 1
Feed it real data
Import a launch-monitor CSV, upload a swing video, snap a screenshot of a stats table, or log a session manually. The more honest the input, the sharper the diagnosis — the engine is upfront when it has too little to be confident.
- 2
Read the priority fault first
Open your diagnosis and start at the top. The single highest-priority fault is the one to work on now; resist the urge to chase the secondary items until the first is retested.
- 3
Check the evidence and confidence
Expand the finding to see which data points drove it and the confidence label. If the confidence is low, add another session or a clearer video before committing practice time to it.
- 4
Send it into a Fix Stack
Turn the priority fault into a Fix Stack — a body cue, a matched drill, and a retest — so the diagnosis becomes a concrete practice loop instead of just information.
- 5
Re-run after focused practice
After a week of working the fix, feed the engine fresh data and compare. A diagnosis is only useful if you close the loop and prove the change.
Pro tips
- →Capture data under similar conditions each time (same range, same camera angle) so the engine is comparing like with like.
- →If you disagree with a finding, look at the evidence it cites — usually it has spotted a real pattern you were discounting.
Good to know
Each finding includes the evidence used to reach the conclusion, likely causes, and what to expect if the issue is corrected.
- • It is a rules-and-benchmarks engine, not a launch monitor or a biomechanics lab — it is only as good as the data you give it.
- • Single-camera video reads are estimates; treat them as a confident starting point, not measured truth.
Frequently asked questions
Does the Diagnostic Engine need an account or internet connection?
Standard video analysis runs on your device. Golf CSV and manual guest previews send mapped shot values to SwingVantage for a deterministic report, so they need an internet connection. One unsaved data preview is available per recognized browser. Saving, plans, retests and exports require an account. Optional AI review is separate and shown only when available.
Why does it only show one priority fault?
Because improvement comes from focused repetition, not scattered attention. Working a single highest-leverage fault to a retest beats nibbling at five at once. The others stay visible so nothing is hidden.
How is this different from a launch monitor?
A launch monitor measures what happened (ball speed, spin, path). The Diagnostic Engine interprets it — it tells you which number is the real problem, why, and what to do, ranked by impact.

Confidence Labels
Every diagnosis shows a confidence level and lists exactly what data was used. When data is limited, SwingVantage says so rather than guessing.
Competing Hypotheses
For golf diagnoses, SwingVantage shows the secondary issue most likely to co-exist with the primary fault — helping you understand pattern relationships rather than treating issues in isolation.
Fix Stack — One Fix at a Time
SwingVantage finds your single highest-impact issue and turns it into a three-step loop: one body cue to feel, the best-matched drill for your level and the gear you have, and an honest before/after retest.
