The What’s in My Bag prompt builds the classic flat lay seen from above with your product standing out among everyday items, the discovery format that gets saved a lot. It works in NanoBanana, in Gemini and in ChatGPT.
1) Send the photo of your product with the JSON prompt in the same message.
2) Keep "preserve_product" so the item shows up identical to the one you sent.
3) Choose the companions in "companions": an open bag, phone, keys, lip balm, sunglasses and earbuds.
4) Set the surface in "surface" (a bed or neutral fabric) and the overhead angle in "angle".
5) Generate and adjust the items until the composition is balanced and the product is the centre of attention.
Tip: soft daylight keeps everything tidy without looking like a catalogue photo.
