Copy a prompt. Fill in the brackets. Get direction.
Each prompt starts with "Using the JRcmo Brain, tell me", so your AI answers from the laws. Replace the [brackets] with your own details.

- Use real numbers. Spend, leads, close rate, average sale. The answer gets sharper.
- Paste the actual thing. Your ad, headline, report or conversion list beats a description of it.
- One question at a time. Then ask "What's my next step?"
Same question. Two answers.
Watch plain AI and AI with the Brain answer the same marketing question, side by side. Pick an example or let it play.
Five situations. Two very different answers.
Plain AI gives you the answer your competitor got this morning. With the Brain, you get the law that applies and the fix, before a dollar moves.
| When this happens | Plain AI says | The Brain says |
|---|---|---|
| Leads dropped this month | Refresh the creative and the offer | Change one variable, measure it, lock the gain (Law 3) |
| The report shows zero conversions | Shut the channel off | Test what happens to total leads when it's off first (Law 15) |
| Google Ads shows 0.44 conversions | Call it progress | You can't have 0.44 of a customer. Something fake is counted (Law 16) |
| You need a new headline | "Quality service you can trust" | Name the damage your buyer is about to suffer (Laws 4 and 10) |
| You want to show up in ChatGPT answers | Write more blog posts | Answer plainly in your first 150 words, same facts everywhere (Law 19) |
