Draft the product description you have been avoiding
When you are adding a product and the description box is empty → then click the generate icon in the toolbar and give it the product's real features, any keywords, and the tone you want.
Why this one: Swap-tested against Squarespace AI, which will also write you product copy. What is specific to Shopify is what it prints beside the button: that you are "responsible for the accuracy of all of the content that you publish to your store," and that the generator "can include things such as product benefits even when you didn't list any explicitly." Doing one product first, slowly, teaches you exactly what it invents.
Tweak: Feed it the three facts a customer actually asks about — what it is made of, what size it is, what it is for — and one tone word. Shopify's help centre says the prompt (the message you type) can carry "product features, keywords, desired tone, or any other instructions," and the generator already has the product title for context.
