Build a basket of specific products you bought (or want to compare).
Load a photo of a receipt or type into each row to search the catalogue
— pick a suggestion to lock the row to that exact product.
Click Compare across shops to see what the same basket
would cost at every other supermarket.
For best OCR results:
Flatten the receipt — fold lines and crumples kill OCR.
Even, bright lighting — daylight is best.
Receipt fills the frame — get close.
Plain dark background — wood, dark fabric, stone.
Square-on, not at an angle.
Sharp focus — tap the screen on the receipt before shooting.
No glare.
Long receipts: split into multiple photos with ~3-line overlap so we can stitch.
Paste receipt text directly as DESCRIPTION | PRICE lines (one per row).
Use this when you have a digital receipt or want to skip the OCR.
