I've been building something small that I think is useful, and I'd like a few of you to try it. It's called a tutor file. It's one plain file about one subject. You load it into your own AI, Claude or any other, and from then on the AI tutors you from it. It asks what you already know, takes you through one part at a time, and checks you've got it before moving on. You can say "quiz me" or "explain that another way" or "I'm stuck on this". It works on your phone. There's nothing to install. Here's one to try. I picked something harmless: how to make a homemade pizza. The file: https://dmpgh.com/teach/homemade-pizza-tutor-file.md A three-minute first look at the topic: https://video.dmpgh.com/w/etf6Cetnwy4TPzJBF1Z2fD How to use it: 1. Open the file and copy all of it, or download it. 2. Start a new chat with your AI and paste it in, or attach it. 3. Type: "You are my tutor for this file. Teach only from the file. Start by asking what I already know." Two honest things. This one was written from general knowledge, and the file says so, so check anything that matters. And it's new. I've made about half a dozen. Now the offer. Tell me a topic in the comments, and who it's for, and I'll make you a tutor file on it. If you have your own notes on the subject, even better, because then every fact in it comes from you. What would you want to be tutored on?
