[POSTER] How to make a premium poster in 5 minutes ⬇

Stop wasting money on a graphic designer for every little thing.
Seriously – just a photo of your product and this prompt, and in a few minutes you have an ad that looks like it was made for several hundred zlotys.

👉 Take a picture with your phone (I used Sony headphones).
👉 Upload it to Chat.
👉 Paste the prompt below and fill in a few variables: name, slogan, benefits, CTA.
👉 And in a moment you have a sales poster that any agency would be proud of.
👉 Remember - often you need to make adjustments, regenerate. It's standard in AI.

This prompt works in such a way that first ChatGPT will ask you for the necessary details – the product name, slogan, 3–5 benefits, call to action, as well as any additional elements (e.g. -30%, “bestseller”). You just respond, and only then does it prepare a ready poster design based on that.

There is no magic button “Generate” here – the whole process takes place in a conversation with the Chat. You paste the prompt, upload the photo, and answer the questions. The final effect is a professional poster in 4:5 format, ready for social media or print.

Below you have the complete prompt that you can immediately paste into ChatGPT and use for any product.

PROMPT

Task for AI:

Act like an experienced creative director from an advertising agency, specializing in creating eye-catching and effective sales posters. Your task is to transform a regular product photo (e.g. taken with a phone) into a professional, converting advertising poster in 4:5 format – perfect for social media, sales pages, e-commerce, or advertising campaigns.

🔁 WORK STRUCTURE:

Step 1 – gather data from the user:

After attaching the photo, do not generate the poster yet. Instead:

Display to the user a list of information you want to obtain from them.

For each variable, provide 1–2 short examples.

Ask the user to provide the textual information that you will then use to create the graphic.

Step 2 – create the graphic:

Once the user provides the complete data – generate a ready sales poster using the uploaded photo and the provided information. Everything according to the style described below.

📌 REQUIRED INFORMATION FROM THE USER (DISPLAY AND ASK FOR RESPONSE):

1. Product name

e.g. “CREATOR – AI in liquid”, “HydraBoost 2.0”, “Luna Glow Serum”, “Business Planner 2025”

1. Slogan / advertising tagline

e.g. “The power that drives you”, “Skin like after treatment”, “Your productivity assistant”

1. 3–5 features or benefits

e.g. “1000W power”, “BPA-free”, “Works 24h”, “12 chapters of practice”, “Designed by a dietitian”

1. Call To Action (CTA)

e.g. “Buy now”, “Order today with a discount”, “Sign up”, “Learn more”

1. Additional elements (optional):

e.g. “-30%” in the background as a watermark, “New”, “Bestseller”, “Available at: creator.store”

Ask the user to enter all this information in points (1–5).

 

🎨 POSTER STYLE (GRAPHICS):

Once you receive the data – create a modern, eye-catching product poster:

The product centrally placed, well visible, with natural light and a subtle shadow.

The background smooth or gradient, matching the product's color scheme.

Add texts from points 1–5: name, slogan, features, CTA.

You can use icons, badges, or pictograms (e.g. dots, symbols, frames) to present features.

If the user added an element from point 5 – weave it in as a background or detail.

📐 TECHNICAL PARAMETERS:

Format: vertical 4:5

Style: clean studio, minimalism, subtle modernity or premium render

Export: high resolution, ready for social media or print

Language of texts: as provided by the user (do not translate)

Product from the photo: do not change its appearance – use it exactly as it looks
