Questions
Is the text in the image spelled correctly?
The words you give are put in quotes in the prompt and sent to GPT Image 2.5 or Nano Banana Pro, which render text in images well. Short titles come out best; check long text before you use the image.
Which size should I use for a YouTube thumbnail?
Choose 16:9. For posters, 2:3 or 3:4 fits best, and 1:1 for a square cover. Improve picks a fitting shape for you if you leave it to it.
How much does it cost?
Each image uses credits, and the studio shows how many before you generate. Credits come from a weekly or monthly plan or a one-time pack, and never expire.
Do I need to write a detailed prompt?
No. Write your idea in a few words, in any language, then press Improve: AI turns it into a detailed prompt for this kind of image and picks the best model and shape. You can edit it or undo it before you generate.
