Swap the dummy product for your real product
Upload your product and a mockup scene — optionally add swap notes. AI uses both images (and your notes when provided) to write the Bria instruction — generate instruction only, or run the full pipeline with Nano Banana 2.
Large photos are automatically compressed to 2.0 MB each (4.0 MB combined) before upload.
Product (Subject) Image
REQUIRED
Mockup (Background) Scene
REQUIRED
Swap instructions
OPTIONAL
Optional: describe what to replace and any integration details. Without notes, the Bria instruction is inferred from both images alone.
What to generate
Instruction only — Gemini writes the Bria instruction from your two images and optional swap notes (copy it to gemini.google.com if you like). Instruction + image — same instruction, then Nano Banana 2 renders the final mockup. Requires GEMINI_API_KEY.
