In 2026, it is hard to hold our attention and learn anything deeply. We ask AI agents our questions and forget the answers by morning. We rarely have the quality time ittakes to read a book and understand a topic deeply. There are no learning paths personalised and curated for us, and no deliberate practice that proves you actually know something instead of only being able to look it up on Claude. So I built Course Creator , a skill for Claude Code and Codex that turns anything you want to learn into a real course. https://github.com/ShivamGupta42/course-creator You give it a topic. It builds a full course you open in your browser: a path from beginner to advanced, every idea rebuilt from first principles, a hands-on project in every lesson, and quizzes that explain why you were wrong. I have already used it to build 12. You can click into any one right now, nothing to install: Live: https://shivamgupta42.github.io/course-library/ https://preview.redd.it/tzg0x3a2nh9h1.png?width=2560&format=png&auto=webp&s=d81c69a02387d8a99cdfbbaf6cc8868d6df1b576 What it actually gives you: A clear learning path. 25 lessons in three tracks, beginner to advanced, instead of a single answer that leaves you where you started. You understand, you do not memorize. Every idea is rebuilt from first principles, Feynman style, then explained back in five plain sentences. You build something every lesson. A hands-on project ends each lesson, plus interactive labs you can play with. It explains the reasoning behind common mistakes. Get a quiz wrong and it tells you which idea you confused and why the right answer wins, instead of just “incorrect.” https://preview.redd.it/wkjm1at4nh9h1.png?width=1716&format=png&auto=webp&s=462ae015558b6c47d36d1d3914f9023f43bd1a32 You grade yourself. Every project comes with a rubric and a pass line, so you know when you have actually got it. It is tuned to you. Tell it who it is for and how deep to go, and it builds for that. For e.g. uses the following image that is part of system design course to you if you are a beginner https://preview.redd.it/53jnfs0knh9h1.png?width=1508&format=png&auto=webp&s=d34d78e85f17fcaec9d9df955ab5f74ab5769f4d What is the one thing you have always meant to learn and never got to?
