Nano Banana 2 Prompt Generator

Nano Banana 2 is Google's production-grade image model, notable for two things: near-perfect text rendering and unusually literal instruction following. Where Flux wants cinematic prose and Midjourney wants terse evocative phrases, Nano Banana 2 prefers clear, plain-English directives - "Create a wooden shop sign in a Tuscan street. The sign reads 'Trattoria Luna' in vintage serif. Warm afternoon sun." No photographic jargon, no weighted tags, no --flags. This generator turns your short idea into that shape: a single direct instruction paragraph with any quoted text placed verbatim inside quotation marks so Nano Banana 2 renders it crisply. The model tolerates longer instructions than FLUX or DALL·E 3 without losing subject coherence, which makes it excellent for multi-subject scenes, signage, product packaging mockups, and text-heavy editorial layouts. When you need the inverse - a reference image decoded into Nano Banana-ready instructions - switch to our companion image-to-prompt tool above.

Frequently asked questions

What makes a great Nano Banana 2 prompt?+
Nano Banana 2 (Google) is exceptional at text-in-image and responds best to clear, plain-English instructions. It doesn't need photographic jargon - instead, write short, direct sentences stating the subject, the scene, and any visible text in quotation marks. The generator structures your idea as a concise instruction paragraph rather than a descriptive blob.
What is an AI prompt generator?+
An AI prompt generator rewrites a short idea into a longer, model-specific instruction that steers an image model toward better, more predictable results. Different models prefer different prompt styles - Flux likes long natural language, Stable Diffusion likes a hybrid of description plus tags, Midjourney likes terse evocative phrasing with parameter flags, and Nano Banana 2 likes plain logical instructions.
Is the AI prompt generator free?+
Yes. Anyone can generate up to 5 prompts per day at no cost, no sign-up required. If you need more, the EdMyPic Free plan includes 5 photo edits per day plus unlimited prompt generation when signed in.
Which AI image models does this support?+
Eleven major models out of the box: Flux 1.1 Pro, Midjourney v6, DALL·E 3, Stable Diffusion 3, Stable Diffusion XL, Ideogram 2, Leonardo AI, Google Imagen 3, Google Nano Banana 2, Adobe Firefly, and Recraft V3. Each one ships with a hand-tuned system prompt - pick the model you'll be generating with so the output matches its conventions exactly.
How do I get the best results from a prompt generator?+
Start with a clear subject (who or what), a verb (what they're doing), and one stylistic anchor (e.g. golden hour, cinematic, watercolor). The generator handles the rest - composition, lens, lighting, and mood - based on the model you selected.
Can I use the generated prompt commercially?+
Yes. The prompt itself is just text - you own anything you generate from it. Commercial usage of the resulting image depends on the image model you're using; Flux, SD3, and Midjourney all support commercial output on their paid tiers.
Why does the same idea give different prompts for different models?+
Each model was trained on different data with different guidance objectives. A description that nails a photoreal portrait in Flux 1.1 Pro will under-perform in Midjourney unless you switch to Midjourney's more compact, flag-based syntax. The model selector handles that translation automatically.
Do I need to know prompt engineering to use this?+
No. The whole point of the tool is that you don't. Type a rough idea like "a barista smiling at golden hour" and you'll get back a fully-formed prompt that incorporates the photography, composition, and mood cues the model needs.
