Made for words and images

Describe the image, quote the words

A menu needs its prices. A poster needs its date. Start with what matters, then describe the feeling around it.

Learn how layout JSON works

Give every word a place.

Quote the headline, separate the details, and tell the model which line should lead. Always proofread the result before publishing.

Sketch the composition.

Place text and artwork in separate boxes, then turn your sketch into a layout prompt. Boxes guide the model; they do not guarantee exact placement.

Bring the whole brief.

Describe the paper, palette, hierarchy, subject, and spacing together. Keep each instruction consistent so the model has one clear design to follow.

Place text box by box with the Layout Builder

Switch the generator to Layout Builder and draw a box for each headline, date or illustration. The builder writes the MOSS-Image JSON layout for you, and boxes keep their relative position when you change the aspect ratio.

Frequently asked questions about MOSS-Image

Can I use MOSS-Image without installing ComfyUI?

Yes. This studio runs in your browser, so there is nothing to install or configure. Sign in, write a prompt and generate. It is an independent service and is not affiliated with the OpenMOSS team.

How do I specify the exact words?

Put each piece of text in quotes and say where it belongs, for example: Heading: 'MORNING CLUB'. Add a line asking the model to render quoted text verbatim and add no other text. Results usually follow, but check spelling before you use an image.

Can I combine Chinese and English?

Yes. MOSS-Image can render Chinese and English together, such as '花间书店' above 'BLOOM BOOKS'. Quote each line separately and keep it short. Longer passages are more likely to contain mistakes.

Why does text in AI images come out garbled?

Most image models draw letters as shapes, so words come out misspelled or invented. MOSS-Image was trained on long and Chinese text. Write the words in quotes and keep each line short for the best results.

Is this the official MOSS-Image website?

No. MOSS Image Studio is an independent service and is not affiliated with OpenMOSS. The official model repository is github.com/OpenMOSS/MOSS-Image.

What is a MOSS-Image JSON layout?

It is a list of boxes, each with a label (text or object), a description, the exact text for text boxes, and its position on the canvas. The Layout Builder writes it for you when you draw boxes, and you can copy it from the JSON tab.

What are the limits?

Long paragraphs, very small type and busy backgrounds can still produce mistakes, so check every image before you use it. Output goes up to 2K (1920 × 1088 for 16:9, 1440 × 1440 for square). Uploading an image to edit is not supported.

Do credits expire?

No. Credit packs are one-time purchases with no subscription, and purchased credits never expire. A generation that fails returns its credit.
