AI generation works best as an iterative method, not as a one-shot precision instrument. You start with a direction, let the model produce options, evaluate what is working or failing, and then tweak the next prompt or edit pass with explicit reasons. If you are trying to hit a very particular design, expect significant human work in the loop.
Give the AI an idea, a mood, a product goal, or a structural hypothesis. The first generation is there to reveal options, not to prove perfection.
Review what the model produced and say why parts are strong or weak. Evaluation is where human judgment creates useful momentum.
Revise the next prompt or manual edit with specific reasons: hierarchy is weak, density is off, navigation is too busy, or the tone is wrong.
AI is fast at producing alternative directions from a brief so you can compare possibilities instead of staring at a blank canvas.
Even weak outputs are useful because they make hidden design choices visible enough to critique.
AI can help compress the gap between critique and the next candidate, especially when your feedback is specific.
State the design idea in plain language: audience, feeling, layout goals, and what success should look like.
Let the AI produce one or more candidates from that direction instead of demanding exact fidelity immediately.
Evaluate the results and explain what is wrong or right: too dense, weak contrast, unclear focus, off-brand, too generic.
Update the prompt or the design with explicit reasons so the next pass has tighter guidance.
Repeat until the remaining work is better handled by direct design edits than by more generation.
