It drafts.
You decide.
Most AI writers take a prompt and hand back prose. This one takes your catalog — the variants, the options, the price you actually charge — drafts from that, and then stops. Publishing to a live product is a separate, approved step.
A prompt-based writer does not know your store
Paste a product name into a general AI writer and it will produce confident copy about a product it has never seen. The output reads well and asserts things you cannot ship — a fabric weight, a compatibility, a delivery window. Those become returns.
Writing from a prompt
The model fills gaps with what products like yours are usually like. Every gap in your data becomes a confident sentence you now have to fact-check — and the ones you miss reach the customer.
Writing from the catalog
The draft is bounded by the record: your variants, options, price band, tags and existing copy. Where the data is thin, the description stays thin. That is the correct failure — cautious beats plausible.
Draft and apply are different permissions
This is the part that matters, and it is enforced in the agent rather than promised in marketing copy.
Draft — write scope
Ask for a description and you get one back, in the conversation, for that specific product. Nothing on your storefront changes. Read it, argue with it, ask for a shorter one.
Apply — admin scope
Pushing a description onto a live product is a separate, higher permission and prompts for approval. An agent that can silently rewrite your catalog is a liability.
Do the pages that matter
Work through the products that actually get traffic rather than bulk-rewriting everything. Four hundred listings rewritten at once read identically and rank for nothing.
Your record, not a guess
Variants and options
Sizes, colours, materials and the combinations that actually exist — so the copy never describes a variant you do not stock.
Price and positioning
It knows the price band and what else you carry, so a £4 impulse item does not get copy written for a £400 considered purchase.
Your existing words
Where you have already written something, it edits rather than replaces — your terminology survives instead of being flattened into house style.
The same brain as your chat
The agent that writes the description is the agent that answers shoppers about it. A listing and a chat reply cannot contradict each other.
