See your swing in 3D — right in your browser
Upload or record one clip and Motion Lab reconstructs your motion in 3D, breaks it into phases, scores the biomechanics, and hands you the one fix that matters — for golf, tennis, baseball, and softball. No sensors. No special hardware.

What Motion Lab analyzes
One clip, broken down the way a coach would — phase by phase, with every read labeled by how confident we are.
Swing phases
Your motion is split into takeaway, load, transition, contact, and follow-through, so every note is tied to the exact moment it happens.
Kinematic sequence
The order your hips, torso, and arms fire — the engine of power and the most common place it leaks.
Biomechanical score
A transparent 0–100 score built from component sub-scores you can see — not a black box.
Your top fault
The single highest-leverage issue with the evidence behind it, instead of a generic checklist.
Tempo & timing
The rhythm of your move and where it speeds up or stalls.
Shot type (golf)
Detects chip, pitch, punch, half, three-quarter, or full so the read matches the shot you actually hit.
What you'll receive
Every Motion Lab analysis returns one motion score, one prioritized fix, and one drill with a retest target — the whole “one fix, one plan, one retest” loop in a single screen.
A motion score
A transparent 0–100 score with the component sub-scores that built it — so you know exactly why.
Your one fix
The top fault, why it matters, and how sure we are — every read labeled measured, AI-assisted, or estimated.
A drill + retest
One drill tied to the fix and a retest target, so you can prove the change the next time you record.
What a single camera can and can't tell you
- Depth from one camera is estimated, not measured — so 3D angles are directional, and a steadier, side-on clip raises their confidence.
- Lighting, framing, and clip length change how much we can trust each read — every result shows its confidence level so nothing is oversold.
- Motion Lab reads your body, not ball flight. For ball speed and spin, pair it with launch-monitor data.
What SwingVantage can and can't tell you
Every result carries the same honest label everywhere you see it — so you always know what's precise, what's an estimate, and what to trust for your next session. Our free engine does the everyday read; AI is an optional upgrade when you want more depth.
Measured
Read straight from your launch monitor or sensor data. The most precise number we can show.
Estimated
Our free coaching engine compares your swing to research benchmarks for your sport and level. Trustworthy direction you can train on today — no AI required.
Inferred
Want more detail? Optional AI reads your video frames for extra depth on top of the free read. Single-camera limits still apply.
Self-reported
Based on what you describe yourself. Useful context, and as accurate as the details you share.
Free first. AI when you want more depth.
Our proprietary engine gives you a real, trustworthy read for free. AI is an optional upgrade for extra detail — never a wall in front of your improvement.

Film it once, film it right
A clean clip gives you a confident read. Stand side-on or face-on, keep your whole body and equipment in frame from start to finish, steady the camera, and use even light. Normal speed is perfect — Motion Lab slows it down for you.

How Motion Lab works
- 1
Record or upload
Film side-on or face-on with your phone, or upload a clip you already have. One clean rep beats a long video.
- 2
Get your 3D breakdown
On-device pose tracking reconstructs your motion, splits it into phases, and scores the biomechanics in seconds.
- 3
Fix and retest
Work the one drill, then re-record to watch your score move — proof you actually changed it.
The intelligence behind your breakdown
Motion Lab plugs into the rest of SwingVantage — tap any to learn how it works.
Motion Lab (3D)
Turn a phone clip into a 3D figure of your motion you can spin, slow down, and step through — with a phase-by-phase breakdown, scores for power, rotation, balance, sequencing, timing, and consistency, your top 3 fixes, and a practice plan.
AI Diagnostic Engine
A rules-based engine compares your data against sport-specific benchmarks and identifies your highest-priority swing fault — ranked by severity, confidence, and impact on performance.
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.
Swing Score Trends
Track your overall swing score, face control, path control, strike quality, consistency, and dispersion across sessions on a time-series chart.
Frequently Asked Questions
- Do I need sensors or special hardware?
- No. Motion Lab runs in your browser and works from an ordinary phone video — no wearables, markers, or launch monitor required.
- Which sports does Motion Lab support?
- Golf, tennis, baseball, and softball (both slow-pitch and fast-pitch). Each sport gets its own phase model, benchmarks, and fault library.
- How accurate is single-camera 3D?
- A single camera estimates depth rather than measuring it directly, so Motion Lab labels every read by how it was produced — measured, AI-assisted, or estimated — and shows an overall confidence level. It is excellent for finding your top fault and tracking change over time; it is not a replacement for a launch monitor’s ball data.
- Is my video private?
- Yes. Motion Lab analyzes your clip and saves only the breakdown and a small motion track — never the video itself. If you opt into the optional AI vision review, still frames are sent securely for that analysis and nothing is retained afterward.
- Is it free?
- Yes. Motion Lab is free to use — no subscription to get your 3D breakdown and first fix.
