Image to Prompt, tested on 4 AI models

Upload an image. You get a prompt written for each image model, in the style that model follows best. Then run them and see which model recreates your image.

Drop an image here, paste it, or click to choose JPG, PNG or WebP, up to 4 MB. Kingy AI doesn't save your image.

How it works

A vision model (Gemini 3.8 Flash) looks at your image and writes five prompts, following each maker's own prompting advice. When you click Test on 4 models, each prompt runs on its own model through the Vercel AI Gateway. The same vision model then compares each result with your original and gives an AI similarity estimate. That's a model's judgment, not a measurement. Your vote on the closest match feeds a running tally.

Midjourney prompts are written but not tested, because Midjourney has no official API and its terms don't allow automated use.

Limits and privacy

Limits. Each visitor gets 10 uploads and 1 test a day. The tool has a fixed daily budget. When it runs low, tests stop first, then uploads, until 00:00 UTC.

Where your image goes. Your image is sent through the Vercel AI Gateway to Google's Gemini, which writes the prompts and, after a test, scores the results. When you run a test, only the written prompts (not your image) go to OpenAI, Black Forest Labs and ByteDance to make the test images. Kingy AI doesn't save your image or the test images; they go to your browser and are gone when you leave. Each provider handles the data under its own API terms.

What we keep. To enforce the daily limits, we keep a scrambled code made from your IP address that changes every day, never the address itself. We also keep daily totals, such as how many tests ran and which model got each "closest match" vote, with nothing that identifies you. Photos showing a real person's face get prompts but no test images. Only upload images you have the right to use. See also the Kingy AI privacy policy.
