ChatGPT poster prompts

Pick a style, copy the prompt, paste it into ChatGPT. Every style has a sample image, its palette, three versions for common jobs (a gig poster, an Instagram post, a menu) and notes on what to change. 31 styles so far.

How to make a poster with ChatGPT

Decide the words first and keep them short. Pick a style so the picture has a point of view. Paste the prompt, change the subject and the words, and send it. Ask for one change at a time. Check every word before you save the file. The full guide goes through it step by step.

How these prompts are built

Each prompt names a medium, a palette with colour values, a composition, a texture, the exact words to draw and a list of things to keep out. Specific prompts give you more of what you meant. They come from the same written art directions that OpenTempl's Generate tab uses, one for each style.

About the words on the poster

Image models sometimes misspell. Every prompt here includes your words in quotes, and each page tells you to read the result. If you want to fix a word without making the picture again, OpenTempl can leave room for the words and set them as live text on top of the image.

Make it in OpenTempl

OpenTempl is a free, open source design app that works offline and needs no account. Its Generate tab uses these styles with your own OpenAI key. OpenAI charges you for the images you make, and OpenTempl takes nothing.
