Any store: a CSV or a product feed URL
A store on any platform can give Sighted its catalogue as a CSV file or a product feed URL. From there the scoring, the enrichment and the feeds are the same as for Shopify.
What comes in
A CSV in the Google Shopping shape, or a link to a feed you already publish (a Google Merchant Center feed or a Google Sheet, for example). Sighted imports it and scores every product; import it again when your store changes and the scores follow.
What goes out
Hosted feeds for Google Merchant Center (CSV and JSON) and Perplexity Shopping, and a ChatGPT Shopping file for approved OpenAI partners, built from the approved data and rebuilt after each enrichment run, plus per-product Schema.org JSON-LD you can place on your product pages. Writing back into the store itself is Shopify only; on other platforms the feeds are the route to the assistants.
