Articles, Newsletters, and Product Descriptions
Outline anything long, keep a newsletter to one idea, and write product or ad copy only from facts and proof you supply.
Learning objectives
- Start any piece over about 400 words with an approved outline.
- Shape a newsletter as one idea, one story, and one action.
- Restrict product and ad claims to a spec sheet and proof you provide.
01
Why this matters
Long pieces collapse when the draft comes before the outline. Newsletters get ignored when they carry three ideas and no scene. Product copy that invents a certification can become a real complaint, not just a bad paragraph. Ads without proof you supplied are guesses wearing a slogan.
02
Concept
Anything over about 400 words starts as an outline, not a draft. The outline lists the reader, the single claim, the sections, and the fact or story that earns each section. Approve it before prose. A model that drafts first will bury you in paragraphs you feel guilty cutting. Put a word budget on each section. If a section has no fact from you, mark it cut or park it. The outline is a decision, not a warm-up.
A newsletter — a short letter to people who chose to hear from you — carries one idea, one story, and one action. One idea means a sentence a tired reader will remember. One story means a scene from your work, not a survey of the field. One action means a step they can finish in a few minutes. Resist the second idea and park it for next week. The letter should feel finished.
A product description may use only the facts on the seller's spec sheet. Gemini must not invent materials, certifications, or reviews. If the sheet does not say organic, the description does not say organic. An ebook chapter outline is a planning artifact — a map you will still write and edit — not a promise that the model will produce a whole book you can sell unedited. Treat each chapter outline as a brief for a later human writing session.
Advertising copy can follow four slots: claim, proof, offer, and risk reversal — what you will do if the buyer is unhappy, only if you can actually do it. The proof slot stays empty until you supply it. A quote, a number, or a demo must come from your records. If you have no proof yet, narrow the claim or do not run the ad. The model may arrange words. It may not mint evidence or awards.

Real-world example
A kettle sheet that blocked a fake review
A small kettle brand sent a spec sheet: 0.8 liters, stainless steel inside, plastic handle, no certification logos, and a two-year repair promise the owner actually offers. The model draft called it medical grade, hinted at chef reviews, and added a wooden lid. Those lines were rejected because they were not on the sheet. The same week the owner outlined a newsletter: one idea, that the handle stays cooler than the body; one story, a Saturday demo where a customer touched the wrong part; one action, read the handle note before you buy. An ebook outline for a care guide stayed a plan. Nobody treated it as a finished book.

Gemini demonstration
A realistic exchange. Open Gemini beside this page and try a version with your own facts.
You
Spec sheet only: holds 0.8 liters; inside is stainless steel; handle is plastic; owner offers a two-year repair; no certification is listed. Write a product description. Do not add materials, certifications, or reviews. If a feature is absent, say the sheet does not claim it.
Gemini
Description, using only your spec sheet. This kettle holds 0.8 liters. The inside is stainless steel. The handle is plastic. The owner offers a two-year repair. I am not adding medical grade, a wooden lid, chef reviews, or any certification, because none of those words are on the sheet. If a shopper cares about certifications, the honest line is that this sheet lists none. I would also skip cozy mood copy that implies a material you did not name. Suggested order: size, inside metal, handle material, repair promise, then what the sheet does not claim. You should match the repair sentence to the written policy before you publish. If the policy is narrower than two years, the sheet and the ad must shrink together.
You
Newsletter next. One idea: the handle is the part the sheet describes as plastic and it stays cooler than the steel body. One story only if I confirm I saw a customer reach for the body at a Saturday demo. One action: read which part is metal before you buy. Park any second idea. Also list three ebook chapters as a plan, not a book.
Gemini
Newsletter shape: one idea, one story, one action. Idea: the handle stays cooler than the body, so the grip is the part your spec sheet bothers to describe. Story: at the Saturday demo a customer reached for the body and pulled back, then used the plastic handle. Use this only if you saw it or the owner wrote it down. If the demo is fuzzy, leave a blank instead of a charming scene. Action: before buying, read which part is metal and which part is plastic. I am parking a second idea about energy use, because you do not have a number for it. The ebook care-guide outline can list chapters later. It is a plan for writing sessions, not a book to sell this week.

Prompt breakdown
The prompt
Role: copy editor who cannot add facts. Spec sheet: I will paste it below. Task: write a product description using only those lines. Constraints: do not invent materials, certifications, reviews, awards, or test results. If a buyer might assume a feature that is absent, say the sheet does not claim it. Then stop. Do not write the ad's proof slot unless I paste proof. Output: description, then a list titled Refused.
- The role forbids new facts, which is the whole point of a spec-sheet description.
- Naming materials, certifications, and reviews blocks the usual inventions.
- The absent-feature sentence keeps silence from sounding like a hidden benefit.
- The Refused list shows you what the model almost added, so you can watch for it next time.

Common mistakes
Usually
Write a premium description and mention that it is certified organic.
Better
Use only my spec sheet. If organic is not listed, do not say it.
Usually
Turn this outline into a full ebook I can sell tonight.
Better
Keep the chapter outline as a planning artifact. I will write and edit each chapter.
Usually
Add a risk reversal that sounds generous, and invent a customer quote for proof.
Better
Leave proof empty until I supply it. Offer a risk reversal only if I state what I will actually do.
07
Practice exercise
Sheet, letter, and a plan
Done when: A friend can match every material and promise to your sheet, and the newsletter does not smuggle in a second idea.
08
Challenge
No adjective without a line on the sheet
Write a six-line spec sheet for a real product you sell or a simple object on your desk. Include materials and one promise you can keep. Ask for a product description that may use only those lines, then ask for a newsletter with one idea, one story, and one action. Reject any certification, review, or material that was not on your sheet. Sketch an ebook chapter list and label it a planning artifact. You are done when a friend can check every adjective against the sheet.
Hint: Put the proof slot for any ad on a separate line and leave it blank until you paste a record you can show.

Key takeaways
- Over about 400 words, approve an outline before you ask for prose.
- A newsletter carries one idea, one story, and one action.
- Product text may not invent materials, certifications, or reviews.
- An ebook outline is a plan, and ad proof must come from you, including any risk reversal you can truly offer.
