Frequently Asked Questions
What is Nano Banana Pro?
Nano Banana Pro is Google's most advanced image generation model, built on Gemini 3 Pro. It excels at text rendering, character consistency, visual synthesis, world knowledge, and high-resolution (up to 4K) output. Unlike earlier models, it's a "Thinking" model that understands intent, physics, and composition — making it ideal for professional-grade image creation.
How does this prompt generator work?
You fill in structured inputs like subject, art style, composition, and lighting. Our AI then combines these with Nano Banana Pro best practices — using natural language, specific descriptions, and creative direction — to produce an optimized prompt ready to paste directly into Nano Banana Pro via Google AI Studio, Gemini, or the API.
What makes a good Nano Banana Pro prompt?
The best prompts use natural language in full sentences (not keyword tags like "dog, park, 4k"). Be specific about your subject, describe textures and materials, specify camera angles and lighting, and provide context about the purpose. Think of yourself as a Creative Director briefing a professional artist.
Is this tool free to use?
Yes! You get 3 free prompt generations per day with no signup required. For unlimited access to this tool and all our other AI tools, you can sign up for a Promptslove membership which also includes access to 20,000+ premium prompts and courses.
Where can I use the generated prompts?
The generated prompts are optimized for Nano Banana Pro but work well with any advanced image generation AI. You can use them in Google AI Studio, the Gemini app, Vertex AI, or any platform that supports Nano Banana Pro. They also produce great results in Midjourney, DALL-E 3, and Stable Diffusion.
What categories of images can I create?
Our tool supports 10 use case categories: Product Photography, Manga/Anime, Photo Editing, Branding/Logo, Infographics, UI/UX Design, Storyboarding, Content Creation, Text Rendering, and Interior/Architecture. Each category optimizes the prompt for that specific use case.
Why natural language instead of keyword tags?
Nano Banana Pro is a "Thinking" model that understands full sentences far better than comma-separated keywords. Google's official prompting guide explicitly recommends writing like a Creative Director — using descriptive sentences with context, mood, and materiality rather than "tag soups" like "dog, park, 4k, realistic."
How many prompts can I generate for free?
You get 3 free prompt generations every 24 hours. This resets automatically. For unlimited generations and access to all premium tools, consider signing up for a Promptslove membership.
