REFERENCE EDIT / CONSTRAINT CHECK

Change the scene.
Keep the product.

Turn an image-edit idea into an explicit Nano Banana 2 brief. Separate the requested change from locked details, reference roles, exclusions, and ambiguous decisions before you generate.

01 / SOURCE OF TRUTH

Define the edit contract

Use the exact product identity a reviewer must recognize.
CHANGE
One testable instruction per line.
PRESERVE
List identity-bearing details, not “keep everything.”

02 / REFERENCE ROLE

Give each image one job and state what must not transfer.

Required for a usable brief.

WHY THE SPLIT MATTERS

A request is not a constraint.

CHANGE

Say what moves.

Describe the new composition, setting, lighting, pose, material, or text as distinct, reviewable instructions.

PRESERVE

Lock identity.

Name the features that make the source recognizably the same product: geometry, proportions, color, branding, and small details.

REFERENCE

Assign one role.

Explain whether each image controls identity, layout, texture, pose, or mood, and what it must not contribute.

AMBIGUITY

Choose before the model does.

Resolve conflicts such as a hidden logo, cropped object, changed perspective, or incompatible source details.

FAQ

Nano Banana edit brief questions

Does this upload or edit my images?

No. This version accepts text only and structures it in your browser. It does not upload, inspect, or generate an image.

Why separate change and preserve?

An edit request explains the desired difference; it does not automatically identify every product detail that must remain identical. Separating them gives you a clearer review checklist.

What belongs in “reference role”?

Name each source and the single authority it carries—for example, product geometry, pose, composition, or lighting mood. State which features should not transfer.

Is this an official Google tool?

No. It is an independent planning utility and is not affiliated with or endorsed by Google. “Nano Banana” refers to Google’s image-generation model family.

Model capabilities and accepted parameters can change. Review Google’s current image-generation documentation before production use.
