ELDRICK in Grok

What it can and can't do

  • Grok adds ELDRICK as a custom connector at grok.com/connectors. Paste the URL and sign in; there's nothing else to set up.
  • Building on the xAI API instead? ELDRICK's open-source Grok starter (Python and TypeScript) is at https://github.com/chadwittman/eldrick-grok-bot.

Can do

  • Fit a driver, fairway wood, hybrid, irons or wedges from your swing speed (or ball speed), hand, miss and ball flight
  • Search, compare and score real heads and shafts for your swing
  • Size your grip from your hand length, and check the yardage gaps in your bag
  • Find an independent club fitter near a US ZIP code
  • Link to your fitted build on store.eldrick.com

Not yet

  • Putters. ELDRICK fits the other five club types.
  • Checkout inside the chat. Store links open store.eldrick.com, where you pay; nothing is bought until you check out there.

Built on 100,000+ fittings

Including 25,000+ fittings ELDRICK has run. The rules are in the fitting guides and the methodology.

Questions

Grok FAQ

Is ELDRICK free in Grok?

Yes. Every ELDRICK account includes 10 fittings a month. Searching, comparing and scoring clubs and building store links don't use one.

Do I need a launch monitor or my swing speed?

You need your swing speed or ball speed in mph with the club you're fitting, not a launch monitor of your own. A number from a range session, a simulator or a fitting you've had works. ELDRICK never guesses it. Your usual miss and ball flight help; handicap, height and launch numbers are optional.

Does ELDRICK work in Grok on mobile?

Add ELDRICK at grok.com/connectors in a browser. xAI's help pages don't say whether custom connectors carry over to the Grok phone app, so run fittings on grok.com, or use eldrick.com on your phone.

What clubs can ELDRICK fit?

Drivers, fairway woods, hybrids, irons and wedges, the same five clubs as eldrick.com. Not putters yet.

Is my data private?

ELDRICK only gets what the assistant sends it for a fitting: your club, hand, speeds, miss, ball flight and anything else you choose to share, plus your ELDRICK sign-in. ELDRICK doesn't sell or rent your personal information. Fittings are saved to your ELDRICK account, and you can ask hi@eldrick.golf to delete them. Grok's own privacy terms cover the rest of your chat. Read the privacy policy.

Can I use ELDRICK with the xAI API?

Yes. The open-source starter at https://github.com/chadwittman/eldrick-grok-bot connects Grok to https://api.eldrick.com/mcp with the xai-sdk (Python) or the Responses API (TypeScript).
