Does Say It Again work for stores that are not on Shopify?
Yes. Say It Again reads any public store from its address, whatever it is built on. If a store cannot be read, we say so, and you add its products by their links or yourself.
On Shopify and elsewhere
On Shopify we read up to 1,000 products at once. On other stores we read the store, then each product when you paste its link.
When a store cannot be read
If a store blocks us, we say so, and you add products by their links. If we cannot read a page well enough, we say so before you make a video.
Add the product yourself: under a store that could not be read, choose Add a product yourself, and under a product link, Add this product yourself. It asks for the product's name, a description and at least 1 photo.
What it reads from a Shopify store is on its own page: Ads for your Shopify store, made from its link.
