Find out if this offer works before you spend a single hour building it. Most offer validation stops at demand: does anyone want this? The Offer Validation Skill is a Plug & Play Skill that goes further, scoring your next offer idea across six dimensions, so you know whether it works for your specific business, not just for the market in general. An offer can have a hungry market and still fail for you specifically, because it conflicts with your positioning, sits outside what your audience trusts you for, or asks for delivery you can't sustain. Describe your concept, your audience, and what you already sell, and your AI scores demand signals, audience fit, positioning fit, differentiation, delivery feasibility, and price ceiling, each backed by the specific evidence behind it. You walk away with a scorecard, a named list of your most likely failure modes, and, if the offer isn't ready yet, the cheapest test you could run before building anything. 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 PlatformThis 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.
