How to use IrisPrompt

  1. Pick the eye type

    Pick the eye type

    Choose it in the tabs under the logo (Human, Cat, Dragon…), with the ‹ › arrows on the preview, or swipe the preview sideways on a phone. Each type has its own pupil shape and prompt wording.

  2. Choose the shot

    Choose the shot

    Iris macro fills the frame with the iris, Eye close-up shows the whole eye, Portrait puts a face around it. With Both eyes you set up the left and right eye separately — they can even be different types.

  3. Set the colour

    Set the colour

    Pick the Main colour. For two colours in one iris, turn on Heterochromia (central, sectoral, half-and-half or patchy), choose the second colour and adjust rotation, zone size and how soft the transition is.

  4. Add details

    Add details

    Combine any Iris patterns (fibers, crypts, gold speckles, Zombie Eye…), then tune the Limbal ring — the dark ring around the iris — the Pupil size and shape, the Catchlight and the Style. The preview updates as you go; ↻ Another pattern shuffles it, ⬇ PNG saves it.

    Options with this badge (Petals, Spikes, Crown, Inkblot, Burst, Stained Glass, Zombie Eye) work best in GPT Image / Flux.

  5. Copy the prompt

    Copy the prompt

    Above the button, choose your model: Universal, Midjourney, Stable Diffusion, Nano Banana or GPT Image / Flux — the prompt is phrased for it. Press Copy prompt, or Copy for ChatGPT to get the GPT Image format whatever is selected.

  6. Generate

    Generate
