It reads a photo of a supplier receipt or invoice and turns each line into an ingredient update. Sprwt sends the (compressed) image to the AI, which extracts name, item/SKU number, unit price, quantity, total price, unit of measure, pack size and quantity purchased for every line. Each line is then matched to your ingredients, first by the supplier's Item ID stored in the ingredient's Supplier IDs, then by name (exact, or at least 75% similar). Matched lines appear under Existing Items, unmatched under Non-existing Items, on a review page where you confirm prices, base weights, units, stock and macros before anything is saved.
