Why use an image to prompt generator?
Describing an image well is harder than it looks. You need the subject, but also the lighting, the lens, the color palette, the art style and the mood — the details that make an AI generator produce something close to what you have in mind. PromptLens looks at your image and writes those details for you, so you get a strong starting prompt in seconds instead of guessing.
It's useful for recreating a style you like, building variations of your own artwork, learning how good prompts are structured, or writing descriptions for reference images.
Frequently asked questions
Is PromptLens free?
Yes. There's no account and no payment. The site is supported by ads. To keep it fair for everyone there is a small per-minute limit.
Do you store my images?
No. Your image is sent to the AI model only to write the prompt, and it isn't saved by us. The model runs on Cloudflare Workers AI with zero data retention. See our Privacy Policy.
Which AI image generators does it support?
The prompts work with Midjourney, Stable Diffusion (SDXL, SD3), Flux, DALL·E, Ideogram, Leonardo and most other text-to-image tools. Pick the style closest to your tool.
Will the generated image look exactly like mine?
No AI generator copies an image from a prompt alone. You'll get an image with a similar subject, style and mood. For closer results, edit the prompt and add details that matter most to you.
Can I use the prompts commercially?
The prompt text is yours to use. Make sure you have the rights to any image you upload, and follow the terms of the generator you use.
