Your teaching format, captured once, applied to every module you build after. Course Module Builder closes the gap between naming a module and writing it. Most course creators can map out an entire curriculum in an afternoon, then spend months turning each module into recordable lesson content, because every module means re-deciding the same things: how to open, how to sequence the teaching points, when to insert an exercise, how to close. This is an Interview First Skill. It runs a one-time setup interview and builds every module from your captured teaching format instead of a blank page. Give it a module topic and your course context, and it returns a complete module document: an overview, an opening written in your style, every lesson written in full, exercises and reflections framed the way you assign them, and a close that recaps and bridges to what comes next. If your modules come with slides or a workbook, it flags companion material notes against your brand standards too. It fits into building a course, workshop, or membership training on any schedule, self-paced, live, or cohort. You are not handed generic curriculum you have to rewrite from scratch. You are handed lesson content that already sounds like you, ready to record or deliver live. What is a Portable Brain Skill? A Portable Brain Skill is a plain text file, specifically a Markdown (.md) file, that you install directly into your AI account. Claude and ChatGPT both support Skills natively, built on the same open standard, so the exact same file installs in either one. Once it's in, your AI reads it automatically at the start of every relevant conversation, so you never have to re-explain your brand, your process, or your preferences again. It works like permanent memory that loads on demand. Because you own the file itself, you are not locked into any platform. Install it in Claude today, in ChatGPT tomorrow, or in both at once. Your investment travels with your business, not with any single tool. Use It on Any AI Platform This Skill installs directly in Claude and in ChatGPT with no conversion required. ChatGPT's native Skills support works on any paid ChatGPT plan (not available on the free plan yet), and Claude Skills work on both free and paid Claude plans. Every Portable Brain Skill also includes free access to the Portable Brain Skill Extractor, a tool that converts your .md Skill file into formats for every other platform: Google Gem (Gemini) Plain System Prompt Project Knowledge file NotebookLM format Access details are included with your purchase.
