Learn how to write effective prompts that give you the exact results you're looking for
Writing good prompts is the key to getting the exact thumbnails you want. This guide shows you how to structure your prompts for better results.
Bad: "Replace the logo on the right with image one"
The AI doesn't know exactly which element you mean by "on the right".
Good: "Replace the orange logo with Image 1 (the blue logo)"
Adding parentheses to explain what the image is helps the AI understand your intent.
Don't say: "Replace the character on the left with Alex"
This is already handled by selecting your Person. The AI will automatically use your selected person's face.
Bad: "Remove the hand at the bottom left"
Which hand? Be specific about the exact element.
Good: "Remove the left hand pointing at the logo"
When using uploaded images, always clarify what they are:
Replace the orange logo with Image 1 (the blue logo)
The parentheses help ensure the AI understands what Image 1 represents.
Name colors, positions, and descriptions clearly:
Structure your prompt as a list of clear changes:
Replace the orange logo with Image 1 (the blue logo).
Remove the yellow title.
Remove the crown.
Put a dark blue checkered background.
Add a red YouTube-style arrow pointing to the blue logo (Image 1).
If you reference something multiple times, use the same name:
...pointing to the blue logo (Image 1)
Referencing "Image 1" and "the blue logo" together helps the AI stay consistent.
The more changes you request, the harder it is to get perfect results on the first try.
Why? AI is random by nature. Each generation is slightly different.
Strategy:
Starting prompt:
Replace the orange logo with Image 1 (the blue logo).
Remove the yellow title.
After first result, refine:
Replace the orange logo with Image 1 (the blue logo).
Remove the yellow title.
Remove the crown.
Put a dark blue grid background.
Remove the left hand pointing at the logo.
Add a red YouTube-style arrow pointing to Image 1.
The "Images" section in the editor lets you upload extra images to include in your thumbnails. These can be logos, products, icons, screenshots, or any object you want the AI to incorporate.
When you upload images, they're labeled as "Image 1", "Image 2", etc. Reference them clearly:
Replace the phone with Image 1 (the Cursor logo)
Add Image 2 (the MacBook) in the bottom right corner
The parentheses help the AI understand what each image represents.
