What Is Feedough’s AI Image Prompt Library?

Feedough’s AI Image Prompt Library is a free, searchable collection of 10,000+ curated prompts for anyone using AI image generation tools.

Whether you use Midjourney, Nano Banana, or ChatGPT, every prompt has been tested and tagged to help you create high-quality visuals without struggling with prompt engineering.

We created this library to support Feedough’s mission of making advanced tools accessible to all. There is no paywall and no friction. Just copy the prompt, paste it into your AI tool, and generate images.

Why Prompts Matter in AI Image Generation

AI image generators depend heavily on the instructions you give them. A simple prompt like “a cat” usually produces generic results.

A detailed prompt that includes style, lighting, composition, mood, and artistic references helps the AI produce much better images. Well-written prompts guide the model toward more creative and professional results.

Our library provides these ready-to-use prompts so you can generate better images instantly.

Every prompt card shows the image the prompt produced, its title and the start of the prompt. Click Copy prompt to grab the full text, then paste it into Midjourney, Nano Banana, or ChatGPT.

Open any image to see the full prompt and its tags for style, subject, mood and technique. Use the Style, Subject, Mood, Technique and Genre menus to narrow the gallery, or search for a word like “neon”, “logo” or “portrait”.

Many prompts end with Midjourney settings such as --ar 2:3 or --v 6. Keep them in Midjourney. For Nano Banana, ChatGPT and Flux, delete everything from the first -- onwards and describe the shape in words, for example “tall portrait format”.

Best AI Image Generators to Use With These Prompts

Our prompts are optimised for three major AI image platforms.

  • Midjourney works best for artistic and atmospheric images.
  • Nano Banana (Google’s image model) leads for photorealistic, high-resolution results.
  • ChatGPT is strong at accuracy, text rendering, and easy back-and-forth iteration.

Can’t find the image you have in mind? Describe it to the Midjourney prompt generator, the Nano Banana prompt generator or the ChatGPT image prompt generator and get a prompt written for that tool. Have a picture already? The image to prompt generator writes the prompt that recreates it.
