What it does
Copy written without research sounds like every rival. Copy written from real customer words sounds like the buyer's own thoughts. Most owners skip the research because it takes days. This skill hands the research to an AI with deep research or web access. The AI first writes its own research prompt from your product page, then runs it. It collects what buyers say on forums, in video comments and in reviews, plus the fixes they tried before. From that it builds four short documents you can reuse for every page, ad and script: the research itself, an avatar sheet, an offer brief and a list of beliefs the buyer needs. It also pulls four to six buyer archetypes. You save them once as PDFs and upload them each time you write.
You give it
- Your product page saved as a PDF without images
- Product, price, what it replaces and who buys it
- Reviews, support emails or survey answers (optional)
- Existing advertorials (optional)
- Customer words (optional)
- A draft (optional)
You get
- A research document of 20 to 60 pages with customer quotes and their sources
- An avatar sheet with pains, goals, drivers and a quote bank
- An offer brief with awareness level, sophistication stage, big idea, mechanism and name
- A list of at most six beliefs a buyer must hold to buy, plus four to six buyer archetypes
Use it when
- You are about to write a product page, ad or advertorial and have no written research to work from.
- Your copy sounds generic and you want it grounded in what buyers say.
- You want an AI to write for you and need to give it the same facts every time.
How to use it
- Start a chat with the skill. Open it if you added it to your AI, or copy it and paste it in.
- Attach your product page as a PDF without images, and say who buys and what it replaces.
- Let the AI write its own research prompt, then run it with deep research on. Answer its questions and wait 8 to 20 minutes.
- Check every study, name and number it found before you use any of it.
- Save the four documents as PDFs and upload them every time you write a page, ad or script.
