Context
A fashion DTC with 1,200 active SKUs and constant catalogue rotation. Each product page needed persuasive copy across 3 languages and 2 segments (B2C and pro).
Challenge
Marketing spent 2 days a week writing copy. Freelance pros took 7 days and charged €12–20 per page. With 1,200 SKUs, scaling was impossible. Existing copy was mediocre and conversion had plateaued.
Solution
We built a copy generation system with Claude that: (1) reads product attributes from Shopify, (2) queries the audience segment, (3) generates 3 copy variants + title + meta description, (4) runs A/B tests against a human control, (5) auto-scales the winning variant. Marketing approves in bulk (50 SKUs/min).
This is the typical story e-commerce teams face: volume needs, limited budget, conversion that hinges on text quality.
The A/B test was the mental shift. For 4 weeks, 50% of traffic saw human copy and 50% saw AI copy. When the numbers confirmed a sustained +34% on B2C (and +21% on B2B), the conversation flipped from “will AI replace the copywriter?” to “how do we scale this to the other 5 countries?”.
Spoiler: we scaled to 5 countries in another 6 weeks. The copywriter now runs editorial strategy.
"AI does the first draft. I curate. We went from copywriter to editor — and the business scales."
