A checklist for “rewrite Claude Opus product descriptions”

If you are social media managers in Europe, that checker is often Copyleaks, Turnitin, GPTZero. Read the output against something you wrote last month. If the new product description sounds like a different person, edit toward you, not toward a more “academic” model voice.

What a good result looks like

How to do this in HumanifyLab

1. 1

   Paste the Claude Opus draft

   Drop the product description into HumanifyLab. Do not strip the real differentiator — those are the parts a human author would never regenerate.

2. 2

   Rewrite for voice, not synonyms

• Letting Claude Opus invent sources inside the product description.

• Submitting without reading the output against who it is for and why.
