AI prompt generator: questions
Which AI models do these prompts work with?
Any model that takes a written description: Nano Banana and Nano Banana Pro, GPT Image, Seedream, Grok Imagine, FLUX and others. Models that edit photos also use the 'keep my face' line to hold your identity.
Is the prompt generator free?
Yes, with no sign-up and no limit. It runs in your browser and simply assembles your choices into a well-ordered prompt.
How long should an image prompt be?
Most current models do best with one or two full sentences, roughly 30 to 80 words: subject first, then setting, light, camera and finish. Very long keyword lists tend to blur the result.
