I thought it was impossible to create a YouTube banner with AI that had the correct dimensions and kept my logo visible on desktop and mobile- until I tried ChatGPT 5.6 Work on the highest thinking setting. I have a Plus subscription, so you may need that to access the same model, but it is worth checking what your free account offers first.
So even on my plus subscription, when I used the chat mode, the AI failed miserably to create an image that had the right dimensions for a YouTube cover and at the same time had the logo I needed for the area that shows up on both desktop and mobile. At some point I wondered whether the work agent could potentially prioritize the tasks needed to happen in the correct order, and therefore have more success in achieving the goal. And OMG it did!!! I was blown away!
Here is the prompt that I used. Take into consideration that I already had a reference image for the logo. So you can create what you like first and then ask it to include it into a YouTube cover. Just take into consideration that I spoke the prompt into the voice recognition tool, which was then transcribed. So the grammar is a bit weird! The order of described events though was very deliberate and probably the reason why it succeeded.
The Exact Prompt I Used to Create My YouTube Banner with AI
(Attached two images, one with the text logo and one with the landscape and logo reference it had created in previous “chat” experiments” which Iiked.)
The goal is to create an image that can be uploaded into YouTube as a cover image. In order to achieve this, you need to find the correct dimensions for the YouTube cover. Then you need to use that as a canvas for the image that you will create. In the area of the image that is displayed on desktop, we need to have the logo visible. However, it would be great if this is visible also for mobile. So you need to map out the exact areas that cover the mobile and the desktop. But you must not make that visible into the image. It has to be the areas that only you know, unless, of course, you want to temporarily sketch that and then remove it. You can create some background for the rest of the image that matches it. However, the most important part is the desktop and mobile area. If we can make it look good for TV, that’s also nice.
That’s it! That’s all it took for the AI to create my perfect amazing YouTube cover. Have fun with it!
