Should you use AI to write product descriptions?

Yes for the first draft, no for the last. It is genuinely good at turning a specification into readable prose and genuinely bad at knowing which detail the buyer cares about.

Why the answer is what it is

The workable process: give it the real specification and the real objection customers raise, then edit for the one sentence only you could write. Descriptions published unedited read identically to every competitor using the same tool.

What this looks like in practice

AI is good at the volume work — descriptions, alt text, replies to the same question. It is poor at deciding what to sell.

Generated product photography still reads as generated to a customer more often than the people making it believe.

A recommendation engine needs enough purchase history to have anything to recommend. Below a few thousand orders it is guessing.

Where a mobile app comes into it

The practical consequence for a store: what an assistant can read about you decides whether it recommends you. Plain, checkable facts beat marketing copy.
