Description
Convly is an independent, data-first reference for AI models and the hardware that runs them, and its Image-to-Prompt Generator is a free tool that turns any image into a ready-to-use AI prompt. Upload or paste an image and a vision-language model describes it, returning a detailed text-to-image prompt, a negative prompt, a style breakdown and suggested settings — such as Midjourney's --ar and --stylize, or a sampler, step count and CFG scale for Stable Diffusion (SDXL or SD 3.5).
The tool works on both AI-generated images and real photographs, screenshots or hand-drawn art, because it describes the visual content rather than reading back a stored prompt. The same output serves as a starting point for Flux, DALL-E, Ideogram or any other text-to-image model. Convly is transparent that a finished image does not contain its original prompt or seed, so a vision-model reconstruction is a close estimate, not a byte-for-byte original.
The Image-to-Prompt Generator is completely free, needs no account, has no daily limit for normal use, and works in seven languages. It sits alongside Convly's broader research offering, which includes a hand-verified AI models database, an API cost calculator, an LLM VRAM calculator and a self-hosting vs API break-even calculator.
