TL;DR a competitor's blog, a supplier pitch, or a customer email thread.
The everyday operating tools of a one-to-five-person business: shrink a product photo for the marketplace, generate a QR code for the storefront, check the exchange rate before quoting a customer, generate UUIDs for an import, summarize a competitor blog post, count the words on a product description. Cheap, fast, and your inventory photos never leave your device.
Yes. Unlike the browser-only tools, summarizing and translating send the text to an AI provider to be processed. Do not paste anything you would not send to a third party, and prefer anonymised excerpts for customer data.
Use it to understand their positioning faster - then write your own copy. Republishing a lightly rewritten version of someone else’s page is a copyright problem and reads as filler.
That is one of the best uses. Summarise or translate the message, keep the original for the record, and confirm the commercial details (price, lead time, quantity) with the supplier in writing.
