Most product descriptions are a list of features. Size, color, materials, a few bullet points. They describe the product, but they don't sell it, because nobody buys a feature. People buy the end of a problem they're tired of living with.

This skill teaches your AI to write the other kind. It follows a framework Jonathon Byrdziak, Sulla's founder, uses to teach store owners to write product pages: start with the buyer's real situation, show why the usual options fail them, make the offer clear, remove every doubt and ask for the sale.

Why most descriptions don't sell 01

They start with the productThe reader doesn't care yet. They care about their problem.
They skip the “why not just…”Buyers already have an answer in mind: the gym, the agency, the cheaper option. If the page doesn't deal with it, they leave.
They leave doubts hangingNo proof, no guarantee, no answers to “will this work for me?”

The fix isn't cleverer words. It's putting the right things in the right order.

Use it in one line 02

You don't install anything. Open the AI you already use and paste this:

Paste into ChatGPT, Claude, Gemini or Sulla
Learn this skill and use it to write my product description: https://skills.sulladesktop.com/product-descriptions/SKILL.md

If your AI says it can't open links, use Copy the whole skill and paste the text instead.1 To use it every time, paste it into ChatGPT's custom instructions, a Claude Project or your AI's memory.

It interviews you first 03

Good copy comes from details only you know. Before writing a word, the AI asks one or two questions at a time about:

The productWhat it is, what's included, the price and what the alternatives cost.
The buyerWho buys it, and how they'd describe themselves.
The painful momentThe everyday scene where the problem shows up.
What's differentWhy this works when the usual advice doesn't.
ProofReal results, testimonials and numbers you can stand behind.

Then it repeats back what it heard and waits for your yes before it writes.

The order that sells 04

The finished page runs top to bottom like this:

  1. Others' results. “Carleigh tightened her thighs in 14 days during her drive to work.” It earns the next sentence.
  2. A headline that isn't the product name. “Now you can (desire) even if (obstacle), without (pain).”
  3. Their painful situation, desire and the cost of waiting. In their words, in a real moment.
  4. Empathy and authority. What you believe about their problem, and who you've already helped.
  5. Why the usual way fails. “You shouldn't have to choose between X and Y.”
  6. The better way. Why this works, then three lines that start with “Imagine…”.
  7. The offer, benefits and value stack. What it is, who it's for, what they'll be able to do, and the price next to what the alternatives cost.
  8. Features, a 3-step plan and the guarantee. What's inside, what happens after they buy, and why it's safe to try.
  9. FAQ and a personal close. Every objection answered, then a short signed note: “From the desk of…”.

Nobody buys a feature. They buy the end of a problem they're tired of living with.

The idea behind the skill

Written backwards 05

Staring at a blank page is the hardest part, so the AI doesn't start at the top. It writes the easy, factual middle first (the offer, benefits and features), then the ending, then the “why the usual way fails” section, and the emotional opening last. By then it knows exactly what the opening has to set up.

Styling comes last, after every word is written.

Honest by default 06

No made-up proof. The skill tells the AI never to invent testimonials, customer counts, results or competitor prices. When you don't have something yet, it leaves a clear placeholder and tells you.

No fake urgency. “Only 3 left” and countdown timers only go in if they're true. Fake scarcity costs you the customer's trust.

Careful claims. It only promises what the product actually delivers, and it flags health, money and legal claims for you to check.

Questions 07

Does it work for services, not just physical products?

Yes. The same order works for services, courses, software and anything else someone pays for.

It's long. Can I get a short version for Amazon or Etsy?

Yes. Ask for it after the full page. The long version gives the short one something real to pull from.

Do I need to pay for anything?

No. It works with the free versions of ChatGPT, Claude and Gemini.

Can I change the skill?

Yes. It's a plain text file. Copy it and edit it.
