Below are my raw, unstructured notes. Turn them into a first draft of [EMAIL / POST / PAGE / PROPOSAL]. Rules: - Use only the ideas in my notes. Do not invent facts, numbers or examples. - Where my thinking is thin or a claim isn't supported, insert [GAP: what's missing] instead of filling it in yourself. - Keep my phrasing wherever it already works. - Target length: [X] words. Audience: [WHO]. My notes: [PASTE NOTES]
One of twenty prompts in the free guide. Every book in the catalogue is built this way — the prompt, then what it is for, then what to do with what comes back.

What makes these different
Four things you can check before you buy
Written against 2026 tool versions
Each book states the month its screenshots and menu paths were checked, and says so where a detail is likely to move. None of it is recycled 2023 material.
Every technique has a good-vs-bad pair
The weak version of the prompt next to the one that works, with a note on exactly what changed. You learn the difference, not just the recipe.
Prompt libraries, numbered and indexed
810 prompts across the catalogue, each one numbered so you can find it again — P-001 to P-200, B-001 to B-120, G-001 to G-120.
A PDF you own, not a seat you rent
Download it once and it is yours. No login, no course platform, no renewal date, nothing to lose access to.

Keyword Match Type Tool
Paste a messy keyword list and get it back as broad, phrase and exact match, plus the three negative types most tools leave out. Cleans duplicates and stray spaces and tells you what it changed, flags keywords Google will reject before you upload them, and exports a CSV that imports straight into Google Ads Editor.
Open the toolDigital Marketing
Invoice Generator
Fill in a form and watch the invoice build beside it. Every optional field — logo, tax number, IBAN, purchase order, discount, shipping — disappears from the document when you leave it empty, so a one-line invoice looks deliberate rather than half-filled. Labels translate into 30 languages across 5 templates, independently of the site, and the print output is the document.
