Image to prompt: turn any reference image into an editable prompt.
An image to prompt generator reads a picture and writes the prompt that would recreate it. Instead of guessing at adjectives until an AI image model lands somewhere near your reference, you start from a description of what is actually in the frame — subject, lighting, composition, palette, medium, mood — and adjust from there.
What Geno returns, and why it is not a caption
Most tools hand back a paragraph. Geno returns 96 dynamically added attributes, each one a field you can read, edit, keep or drop. The set adapts to the kind of image you gave it: a photograph, a 3D render, an illustration and a piece of graphic design are analysed against different taxonomies, because lens and film stock mean nothing for a logo and negative space means something quite specific for one.
That difference is the whole point. A paragraph is something you paste once. Named attributes are something you reuse — keep the lighting, swap the subject, and the next image still belongs to the same set.
Is this an image to text (OCR) tool?
No, and the distinction is worth stating plainly because the two phrases get used interchangeably. Image to text normally means OCR: lifting written words off a scan, a screenshot or a photograph of a document. If that is what you need, an OCR tool is the right tool and Geno is not it.
Geno reads the visual qualities of a picture — how it is lit, how it is framed, what it is made of — and writes a prompt from them. It does not transcribe text in the image. Different job, similar phrase.
Which AI image models the prompts work with
The prompt is plain language, so it works anywhere you can paste one — Nano Banana, GPT Image, Midjourney, Flux and Stable Diffusion included. Inside Geno you can also generate straight from it on nine models without an API key of your own, feed an existing shot back in as a reference to edit it, and crop the result to every social post and IAB ad creative size.
Prompts as text, assembled, or JSON
Every analysis is available as full prose, as an assembled prompt, or as JSON. The JSON form is the one worth reading about separately if you generate in volume or want prompts you can version and vary programmatically — see image to JSON prompt.
Try it on your own reference
The decode is the part worth testing on your own style rather than on a demo. Every account starts with free trial credits — sign in with Google, no card. More on what a credit buys is on the pricing page, and the FAQ covers the rest. For the full path from a reference image to a finished, cropped deliverable, see how it works on the home page.
