Golf Agent
You describe a bad golf shot in your own words, and it works out the likely cause, then gives you one thing to focus on.
Try hitting a bad shot in the demo below. As well as free practice, I've added scored target rounds, a daily challenge that's the same for everyone, a distance chart for your clubs and challenges to hit a set shape. After a miss, the coach card explains it using Golf Agent's knowledge base.
Where it came from
I kept struggling at the range to work out the root cause of my bad shots. I also wanted a project that would give me experience with RAG (Retrieval-Augmented Generation) and n8n, so it was a perfect fit.
How I tested it
I wrote 24 questions about bad shots, then got AI to turn them into 67, including a few it should refuse to answer. It got the cause right on 58 of the 59 it should answer, and on the last one it asked me a question back instead of guessing. It also said no to every question it couldn't answer.
Sometimes it found the right cause but the advice still wasn't great, so I went through every answer with AI's help and rebuilt it. Fully right answers went from about half to over three-quarters, and running all the tests now costs less than 50p.
Whenever I add to what it knows, an automation (built in n8n) runs all the questions again and messages me if anything's got worse.
These days I use it at the driving range through Telegram. I just say what happened with the shot, and the answer comes back in a few seconds. If it gets one wrong, that becomes a new test question.
