Gemini Nano Banana Prompt Directory

Where can I find the best Nano Banana prompts for Gemini?

Designstub is a free, dedicated Nano Banana prompt library organised by style category, community-voted, and built exclusively around Gemini's photo editing model. Unlike general AI prompt sites that cover dozens of tools, every single prompt here is tested for Nano Banana specifically. Browse by category, copy any prompt in one click, and paste it directly into Gemini's Create images panel.

What are the best Nano Banana prompts for portrait and selfie editing?

The Aesthetic Portraits and Realistic Selfie categories on Designstub are the most popular on the site. These prompts are community-voted, meaning the ones at the top are the ones that real users have copied and actually got results from. Upload your own photo into Gemini, pick a prompt from either category, and the model will transform your selfie while preserving your features.

Should I use Nano Banana or Nano Banana Pro for photo editing?

For most casual photo edits such as portrait filters, selfie transformations, retro styles the default Nano Banana Fast model works perfectly. Nano Banana Pro, which uses Gemini's Thinking model, gives better results for complex edits like Sci-Fi compositions, prompts with text inside the image, or anything requiring multiple style references. Prompts on Designstub are labelled where the Pro model makes a meaningful difference.

How do I copy and use a Nano Banana prompt from this site?

Every prompt on Designstub has a one-click copy button. Once copied, open the Gemini app, tap the Create images option from the tools menu, and paste the prompt. If the prompt is for photo editing rather than generation, upload your photo first, then paste. No prompt-writing experience needed.

Are these Gemini AI image prompts free to use?

Yes, completely free with no subscription or paywall. Browse every category and copy any prompt without signing up. A free account is only needed if you want to submit your own prompts or earn contribution points from community upvotes.

How are prompts ranked on Designstub?

Prompts are ranked by copy count. The number of times a prompt has been copied and used directly in Gemini. The most-copied prompts rise to the top weekly, so the ranking always reflects what is actually working for real users right now, not editorial picks or votes.

Can I submit my own Nano Banana prompt to the directory?

Yes. Click Submit Post in the top navigation, fill in your prompt details and style category, and submit for review. Approved prompts go live in the community library. The more upvotes your prompt earns, the higher your contributor score and the more visibility your prompt gets across the site.

What style categories does the Nano Banana prompt library cover?

The library currently covers four categories: Aesthetic Portraits for cinematic and editorial-style shots, Realistic Selfie for natural-looking photo transformations, Retro / Vintage for 80s, 90s, and analogue film aesthetics, and Sci-Fi for futuristic and surreal edits. New categories are added as community submissions grow.
