See the golf decision, not just the number.
GolfVectorLab is a free, browser-based reasoning system for recreational golf. Each tool works through a full decision, not just an answer: the result, what it means, the assumptions behind it, and the useful next question. Nothing you enter leaves your browser.

Golf decisions depend on each other: a fair handicap depends on the tee you play, a practice plan depends on your real club distances. Most golf sites answer one in isolation. GolfVectorLab connects them, so an answer from one tool carries into the next without re-entering the same information.
Handicap & scoring
Course and playing handicap, stroke allocation, and format scoring, worked through with the tee and rules context that actually change the result.
Bag intelligence
A visual read on your carry distances and gaps, built from what you already know about your own bag, not a generic distance chart.
Round & practice planning
Condition-adjusted planning ranges and a practical practice session plan, with the uncertainty shown plainly rather than hidden behind a single number.
What GolfVectorLab is not
GolfVectorLab does not issue an official Handicap Index, post scores to a governing body, provide live GPS or course data, or give in-competition rules rulings. It explains published concepts and produces educational estimates; for an official handicap or Rules of Golf question, use your golf association or the USGA and The R&A directly. See the disclaimer page for the full scope, the methodology page for how each result is sourced, and the full engine library to find a specific decision.
