Quick answer: Eldrick and FitMyGolfClubs both use AI for golf club fitting, but they answer different questions. Eldrick turns swing data into single-club spec and product recommendations — its public API covers driver and iron fitting. FitMyGolfClubs grades the entire bag you already own across 8 fitting factors from its specifications — no launch monitor required — uses launch data where you have it, and its core fitting tools are free. If you want to know whether the clubs you own actually fit, whole-bag analysis is the tool for the job.

What is Eldrick?

According to Eldrick's published materials (as of July 2026), Eldrick is an AI engine that generates equipment recommendations from launch monitor data — swing speed, ball speed, launch and landing angle, attack angle, club path, strike pattern, dispersion, and swing tempo. Its marketing lists drivers, fairway woods, hybrids, irons, and wedges, and it has earned national press coverage. The swing-telemetry approach is legitimate: fresh launch monitor numbers genuinely describe your swing.

Eldrick also publishes a developer API, and its public documentation (July 2026) is more specific than the marketing: the v1 fitting engine covers driver and iron fitting, requires just swing speed or ball speed as the minimum swing input, and returns spec recommendations — loft, shaft flex, shaft weight, length, lie angle — alongside retail product matches with prices. Consumer pricing is not published on its site.

What is FitMyGolfClubs?

FitMyGolfClubs starts from the other end: the clubs you already own. You build your bag in about five minutes — by photo or by hand — and AI grades it across 8 professional fitting factors: club age, weight progression, shaft flex consistency, loft gapping, kickpoint, length progression, lie angle, and torque. Every deduction is traced to a specific club, so you learn not just whether your bag fits, but exactly what to fix first — before spending a dollar on new equipment.

Launch monitor data isn't required, but it isn't ignored either: the Test Club feature grades a club you're demoing from launch monitor numbers (club speed, ball speed, smash factor, attack angle, launch angle), and the free tools below run on your driver swing speed alone.

Who does the AI work for?

This is the question to ask about any fitting technology — including ours. Golf equipment is a category where the buyer rarely has full information: most golfers can't independently evaluate whether a $400 aftermarket shaft upgrade matters for their swing. That information gap is exactly where recommendation engines earn trust — or quietly monetize it. In-person fitting has wrestled with this for years: when the fitter's revenue comes from selling you the clubs, every recommendation carries a structural incentive, however honest the individual fitter.

So here is how FitMyGolfClubs handles it, in writing: our revenue comes from selling analysis — subscriptions and credits — not equipment. We publish a binding commitment in our Terms of Service that recommendations are never influenced by affiliate commissions, and that any sponsored placement must be labeled and kept separate from organic analysis. Two things follow from that in practice, not just on paper. Our AI Fit Assistant gives balanced answers on equipment strategy — ask it about one-length irons or blades and it walks you through the genuine pros and cons for your game, rather than steering you toward a purchase. And because the product is a grade rather than a catalog, it can — and regularly does — conclude that your equipment is fine and the cheapest fix is a $40 lie-angle adjustment, not a new set.

When you evaluate Eldrick or any other AI fitting tool, ask the same three questions: Who pays the company — the golfer or the retailer? Can the engine's output ever be "don't buy anything"? And is there a published commitment that recommendations aren't influenced by what earns the company money? Whatever tool answers those well deserves your trust.

Do you need a launch monitor for AI club fitting?

Less than the marketing suggests — on either side. Eldrick's own API documentation shows its engine runs on as little as swing speed or ball speed, numbers many golfers know without a formal session. FitMyGolfClubs' free tools answer the same single-variable questions — what flex fits my swing speed, what shaft weight, what length — from that same one number, free, no account. The real divide isn't launch monitor vs. not; it's single-club spec recommendations vs. whole-bag system analysis. Spec-based bag grading reads your equipment's actual configuration — shaft weights, flex consistency, loft gaps, lengths, lie — and catches the problems that cause bad launch numbers in the first place.

Is there a free online golf club fitting?

Yes — FitMyGolfClubs offers both a free full-bag grade (5 credits at signup, no credit card) and four standalone tools that require no account at all:

• Swing Speed → Shaft Flex — the right flex (L/A/R/S/X/TX) for your driver speed
• Swing Speed → Shaft Weight — gram ranges by club category
• Wrist-to-Floor → Club Length — iron length adjustment from your body measurement
• Single Club Fit Grader — grade one club without building a bag

Between them, these cover the same ground as a single-club spec recommendation — flex, weight, length — in about ten seconds each.

Can you use both?

Honestly, yes. They're not mutually exclusive: grade your current bag on FitMyGolfClubs to find what's actually broken, and if you then book launch monitor time, bring those findings — and if you want a second AI read on the session data itself, tools like Eldrick analyze exactly that. The expensive mistake isn't picking the wrong AI tool; it's buying new clubs before knowing what's wrong with your current ones.

Which should you choose?

• You want to know if your current clubs fit before spending money: FitMyGolfClubs — whole-bag system analysis is the thing spec-recommendation engines don't do.
• You know your swing speed and want a quick spec answer: FitMyGolfClubs' free tools give you flex, weight, and length in seconds, no account — the same single-variable ground Eldrick's engine starts from.
• You're shopping for a new driver or irons with fresh launch monitor data: either works — FitMyGolfClubs' Test Club grades demo clubs from your numbers, and Eldrick specializes in driver/iron recommendations from swing data.
• You're a coach or fitter managing players: FitMyGolfClubs Pro — client rosters with every player's bag grade, scheduling, and proposals.
