Bring the message you want on the poster. DreamMMer drafts the layout, artwork and typography, then adjusts the copy, colors and composition with you until the poster works.
The composer picks a default model for you; switch anytime before generating. Credit cost depends on the model and resolution.

An AI agent for poster design
A poster has to carry one message clearly: a headline people read first, supporting details second, artwork that sets the mood. DreamMMer works from that structure — you state the message and the occasion, the agent turns it into a visual brief, and you keep directing changes in plain language.
How to make a poster in 3 steps
State the message
Share the headline, the details that must appear — date, price, offer — and the mood you want. Mention where it will be shown: printed, a square post, or a landscape banner.
Review the first draft
The agent designs the poster and shows you the result. Read the text carefully: check the headline is correct, the hierarchy is clear, and nothing important is cropped.
Refine through conversation
Ask for changes in everyday words — a larger headline, a warmer background, a different product angle. Every revision keeps the earlier version available in your workspace.

Event announcement
Design a bold event poster for "NOVA", a fictional music festival. Large headline NOVA at the top, the dates "June 12–14" underneath, a purple-to-blue gradient background with abstract sound-wave shapes, flat vector style.
Check the spelling of the headline and dates before using the result.
Travel campaign
Make a vertical travel poster for "Slow Travel": coastal cliffs at sunset, warm orange light, the headline in elegant white serif lettering at the top, with clear space at the bottom for a tagline.
Read the lettering carefully — generated text can drift from the prompt.
Landscape banner
Design a landscape poster for a Design Week event: bold modern typography, a purple and blue color scheme, and room for a date and venue line at the bottom.
Confirm the aspect ratio matches where you plan to publish it.
Questions about AI posters
Can the AI render text on posters?
Yes — the connected models can draw headlines and short lines of text. Keep the text short and specific in the brief, and always proofread the result. Long passages are more likely to contain glitches; ask the agent for another pass when lettering needs correction.
What sizes and aspect ratios can I use?
You set the aspect ratio and resolution in the composer before generating — landscape banners, square posts, and vertical stories are all supported. The exact options depend on the selected model.
Are AI posters good enough to print?
For small-format prints they usually work well. Generate at the highest resolution the model offers, review the text at full size, and run a test print before a large run.
Can I edit the text after generating?
You can ask the agent to change wording, sizing, or placement in a follow-up message. The result is an image, not an editable design file, so precise re-typesetting is limited to what the model can redraw.
How many credits does a poster cost?
Image generation uses credits based on the selected model and resolution. See the pricing page for current credit costs and your account balance.
Can I use AI posters commercially?
You are responsible for how you use generated images, including the rights to any logos, photos, or names you reference. Review the terms of service and the model provider terms before commercial use.
