USGA's Rules AI answers everyday questions so its experts keep the hard calls
25,000+According to the USGA: Rules AI is trained on more than 25,000 rules queries answered by USGA staff and experts, plus the official Rules and interpretations. According to Golf Digest: about 13,000 golfers had access at the May 2026 pilot launch, the USGA aims for 1 million users by the end of 2026, and all GHIN users are targeted for spring 2027. No accuracy, usage or time-saved figures published yet.
“Rules AI is built upon a foundation of unparalleled data, trained on more than 25,000 specific rules queries addressed by USGA staff and experts.”

- Who
- The United States Golf Association (USGA), golf's governing body in the US since 1894, which writes the Rules of Golf with The R&A and runs the GHIN handicap app. Its Rules of Golf department (six rules staff, per Golf Digest) has fielded golfers' rules questions by letter, email and phone for decades. Rules AI built with Deloitte, the USGA's long-standing professional services provider.
- Problem
- Rules questions come up mid-round, when the committee is on the other side of the course and the pro is back in the shop. Golfers had to email the USGA and wait, or call and maybe reach voicemail, while generic chatbots gave fast but sometimes confidently wrong answers. A small rules team cannot answer every golfer in real time.
- Agent
- Rules AI, in the GHIN app, takes a typed question, checks it is about the Rules, routes it to one of about 500 topics, and has several AI agents draft answers from approved USGA data only; another system checks them for consistency before one answer is shown (per Golfweek). If confidence is too low, it refers the golfer to the USGA Rules team. Rules staff check the tool's answers.

Try it yourself with Deloitte
You run member or player services for a tennis, padel or golf federation, league or club. Goal: plan an AI assistant that answers everyday rules and regulations questions from our official texts only, with my team reviewing its answers and taking the hard cases. My input: [our official rules, regulations and FAQs], [50 to 100 past questions with the answers our team gave, anonymised], [who on the team handles escalations], [our channels: email, website, app]. Give me: 1) the 10 most common question types; 2) a draft answer for each, citing the exact rule; 3) the questions the assistant must always pass to a person; 4) a short reply for when it is not sure, saying who to contact; 5) a weekly review routine for my team. Use only my documents and flag any uncertain answer.What we can do for your club or brand
Federations, leagues and clubs answer the same rules and regulations questions all season, by email and phone, often when nobody is free. The Court can set up an AI assistant that answers from your own rule book, regulations and past answers, cites the exact rule, and hands anything uncertain to a named person on your team, so your officials and staff keep their time for the rulings that need human judgement.

What they did
Craig Winter, the USGA's director of Rules of Golf and amateur status, started the idea when ChatGPT launched in late 2022 and saw fast but sometimes wrong rules answers. Over about two years the USGA and Deloitte structured the rule book, interpretations and past rules queries into machine-readable data. A first pilot drafted replies to email queries, which USGA experts reviewed and refined before sending (per Deloitte). The GHIN app pilot opened at select clubs on 27 May 2026.
How it went
The pilot launched with about 13,000 golfers, and the USGA plans to add users each month toward 1 million by the end of 2026, including about 80,000 Metropolitan Golf Association golfers, according to Golf Digest. Craig Winter: "We want a golfer with a phone in their hand not to have to email us and wait or call us and maybe get voice mail." The USGA says it is not meant to supersede a committee's decision, and club pros running competitions can use it to check rulings. Limits: no accuracy, usage or time-saved figures published yet; the pilot is still being rolled out.
