Questions

Does my prompt get sent anywhere?
No. The scoring runs entirely in your browser in JavaScript. Your prompt never leaves your device, there is no signup, and nothing is stored or logged.
Which AI tools does this work for?
The 10 dimensions are what strong prompts share across Midjourney, FLUX, Stable Diffusion, DALL-E and Nano Banana. A prompt that scores well here works better in all of them.
Is a perfect 100 always the goal?
Not always. A clean minimalist shot may skip a couple of dimensions on purpose. But if you are getting messy or generic results, the missing pieces the checker flags are almost always why.
How is the score calculated?
Each of the 10 dimensions is weighted and checked for the words and patterns pro prompts use, plus a specificity check on length and concreteness. It is a guide to make your prompt more complete, not a magic number.
