What it does well
Text to image
Write the subject, the style and the light, and get a finished image you can use right away.
Edit a photo
Upload a photo, say what to change in one sentence, and the rest of the picture stays as it was.
Pay for what you make
Billed per run, with the total on the button before you generate. Failed runs are refunded.
Settings and prices
Each image has a fixed price; the button always shows the exact total before you generate.
| Setting | Price | Example | Unlimited plan |
|---|---|---|---|
| Pro | 30 credits / image | 4 images = 120 credits | Free |
| Max | 40 credits / image | 4 images = 160 credits | Free |
Prompt tips for better images
Subject first, then style
Say what the picture is of, then add the style: watercolor, film photo, 3D render or flat illustration. Putting the style last keeps the subject from drifting.
Describe the light and the lens
Window light, soft studio light or a backlit silhouette; a 50mm portrait, a macro shot or a top-down view. Light and lens decide how real the image feels.
Use references for consistency
When one character or product appears in several images, upload references and say which features to keep. It is far steadier than words alone.
For edits, say what changes and what stays
For example: "replace the background with a beach, keep the person and the outfit". Change one or two things per run for the most control.
Generate a few, then refine
Ask for two to four images at once and keep the one closest to what you had in mind. Then reuse its prompt, change one detail at a time, and you will reach the final look in fewer runs.
Example prompt
A ceramic coffee cup on a linen tablecloth by a window, soft morning light, shallow depth of field, 85mm product photo.
