AI Graphic Design Prompt Generator: Posters, Thumbnails, Banners

Choose a templateBuilt from real high-performing designs

Your text

Type the exact words. They are copied into the design letter for letter.

Your images

Using your own logo, photo or product? Add it here and say what it is. The prompt tells the AI how to use each image. Attach the same files in Gemini or ChatGPT in this order. Your files stay on your device and are never uploaded.

How to get the best result

Write the exact words you want in the fields. The prompt puts them in quotes so the AI copies them letter for letter.
Keep text short. Headings of 2 to 6 words and 3 to 5 feature points render most reliably.
Upload your logo, product photo or a person's photo together with the prompt, and the AI will use it.
If one word comes out wrong, ask in the same chat: Fix only the word "...". Do not change any other elements.
Change one thing at a time when refining (colour, layout or a single line of text).
Set the aspect ratio in your AI tool's settings too, not only in the prompt.

How it works

Pick a design type: poster, thumbnail, banner, product ad or motion graphics.
Type your text: heading, sub heading, features, offer, call to action and contact details.
Choose style and colours, copy the prompt, and paste it into Gemini, ChatGPT or Ideogram with your logo or product photo.

Frequently asked questions

Which AI is best for posters and thumbnails with text?

Gemini (Nano Banana Pro), GPT Image in ChatGPT and Ideogram render text most reliably. Midjourney makes great visuals but often misspells text.

How do I add my logo or product?

Upload your logo or product photo in the same message as the prompt. The prompt already tells the AI to use the uploaded image exactly as provided.

Why are some words misspelled?

Long text is the main cause. Keep headings short, use 3 to 5 feature points, and if one word is wrong ask: Fix only the word "..." and do not change anything else.

Can I make animated graphics?

Yes. Choose Motion Graphics to get a video prompt for Veo, Kling or Seedance. For the cleanest text, design a still first and animate it with image-to-video.
