Frequently Asked Questions

What is a Nano Banana prompt generator?

A Nano Banana prompt generator creates optimized text prompts specifically designed for Google's Nano Banana (Imagen) image generation model. It uses structured prompt engineering with 10 key components (subject, lighting, camera, composition, etc.) to produce detailed prompts that maximize image quality.

How does character consistency work?

When enabled, the tool locks identity traits like face shape, hair color and style, body build, skin tone, and wardrobe across all prompt variants. This means all 3-5 generated prompts will describe the same character in different scenes, lighting, or compositions โ€” perfect for creating consistent character sets.

Can I upload reference images?

Yes! Upload up to 6 reference images with optional notes for each. The tool analyzes your references and generates prompts that preserve key visual traits while placing the subject in new scenarios. This is ideal for maintaining brand consistency or character likeness.

Whatโ€™s the difference between Plain and JSON Structured output?

Plain mode gives you natural language prompts ready to paste into any image generator. JSON Structured mode adds a labeled breakdown (GOAL, SUBJECT, ACTION, COMPOSITION, ENVIRONMENT, LIGHTING, CAMERA, STYLE, CONSTRAINTS, OUTPUT) for advanced users who want granular control over each prompt element.

Is this tool completely free?

Yes, 100% free with no signup required. Itโ€™s powered by advanced open-source AI models. The tool generates text prompts only โ€” to generate actual images, use the "Generate in PicX" button to jump into PicX Studioโ€™s image generator.

How do I write better Nano Banana prompts?

Focus on specificity: describe exact lighting direction (not just "good lighting"), name camera lenses (85mm f/1.4), include composition details (rule of thirds, leading lines), and specify the artistic style. Always include a negative prompt to exclude common artifacts like blur, watermarks, and anatomical errors.
