Concept art, posters with real text baked in, storybook scenes, quick 'good enough' hero images. Because it lives inside ChatGPT, you can iterate in plain conversation — 'make it warmer', 'add a Pakistani flag on the wall', 'now 9:16 for reels'.
In ChatGPT: just type your prompt. Ask for variations in-thread. Ask it to rewrite YOUR prompt before generating — 'expand this into a full DALL·E prompt with style, lighting, camera'. That single move doubles quality.
