Free Claude skill
A copywriter for your Shopify store, in your voice, every week.
Shopify Copywriter is a free skill for Claude. It learns how your brand writes, pulls what is happening this week for your audience, and writes ad, product page, and email copy that sounds like you. The product-page mode also writes the structured attributes AI shopping agents read, so the page works for the shopper and the agent.
Built by the team at Atomz. Give an email, the download starts.
Three things, done well
Ad, product page, email.
It does these three and routes everything else away. Each mode follows a real scaffold and the character limits the channel enforces.
Ad copy
Meta first, then Google Search, TikTok, and Pinterest. Three variants per ask, one on an emotional hook, one on a specific attribute, one on social proof, each cut to the character limits the platform enforces.
- Meta primary text + headline
- Google RSA headlines
- TikTok and Pinterest captions
Product pages
The marketing copy that converts a shopper, and the structured attributes that decide whether an AI agent ever surfaces the product. Most tools write the first. This one writes both, side by side.
- Product title and hero lead
- Benefit and use-case copy
- Structured metafield payload
Shaped for Klaviyo, where most Shopify stores send from, and portable to any other tool. Subject, preheader, body, and one call to action, written for a drop, a sale, a restock, or the weekly send.
- Subject + preheader
- Body with one clear CTA
- Send-time recommendation
How it works
Reads your brand, reads the week, writes the copy.
It learns your voice
On the first run it reads your store, your About page, and a few product pages, then builds a brand profile: your voice, your audience, your products, and the catalog gaps an agent would trip on. Save the profile once and it stops asking.
It pulls this week's context
It searches for what your audience cares about in the next week or two, a game, a season, a holiday, a cultural moment, and anchors the copy to it. If nothing relevant is happening, it says so and writes evergreen rather than inventing an occasion.
It writes in your voice
Ad, product page, or email, in the brand voice it pulled from your site. No em dashes, no AI filler vocabulary, no exclamation points faking enthusiasm. It reads like someone on your team wrote it.

Real output. Pick a vertical and a mode.
Sample runs for three made-up brands, written in the skill's exact format. Watch the context anchor at the top and the one routed CTA at the bottom of each, the part that sends the reader back here. The product page mode shows both layers, the copy a shopper reads and the structured data an agent reads.
Example brand: Halby. A skincare brand for reactive skin.
What the shopper reads
Title
Hero
Benefits
- 10% THD ascorbate, a gentler vitamin C
- Fragrance-free and essential-oil-free
- Airless pump, no oxidation
- Layers under SPF without pilling
Description
FAQ
Will it sting?
THD ascorbate is far gentler than L-ascorbic acid, so most reactive skin tolerates it. Patch test first if you react easily.
Morning or night?
Morning, under SPF. Vitamin C and daytime sun protection work as a pair.
What the agent reads
active: "tetrahexyldecyl ascorbate 10%" skin_type: ["sensitive", "reactive", "dry"] concern: ["dullness", "uneven tone"] free_from: ["fragrance", "essential oils", "alcohol"] size: "30 ml" routine_step: "morning, before SPF" price_band: "under_60"

Why the product-page mode is different
A product page has two readers.
A shopper reads the marketing copy and decides whether to buy. An AI agent reads the structured attributes in your catalog and decides whether to show your product at all. Most copy tools write only the first, so the page reads beautifully and still goes unfound. The product page mode above writes both, side by side, for every product.
That second layer is the whole job at Atomz. The skill writes it one product at a time, while Atomz fixes it across your entire catalog. If you want to see the gap on your live store, the audit is free.

Questions merchants ask
What is a Claude skill and how do I install this?+
A skill is a folder of instructions that teaches Claude to do one job well. Download the zip, unzip it, and drop the shopify-copywriter folder into your skills directory or add it through Customize in Claude. After that, ask Claude for an ad, a product page, or an email and the skill runs.
Is it really free?+
Yes. You give an email and the download starts. The email also subscribes you to The Agentic Operator, the playbook we write for Shopify stores building for AI shopping agents, and you can leave any time.
Does it write in my brand's voice or a generic one?+
Yours. On the first run it reads your live site and extracts how you write, then writes to match. It does not write in a house style, and it does not write in anyone else's voice.
Why does the product-page mode write structured attributes too?+
Because a product page has two readers. A shopper reads the marketing copy, and an AI agent reads the structured attributes in your catalog to decide whether to recommend you at all. The skill writes both so the page works for the person and the agent. That second layer is the work Atomz does across your whole catalog.
What does it not do?+
It does not make images, edit your existing copy line by line, write blog posts or landing pages, or publish anything. It writes new ad, product page, and email copy, and hands it back to you.
