When to add a custom prompt
A custom prompt is useful when the standard asset flow is correct but you need a more specific result. Use it to define a creative angle, mention a product feature, request a tone, add a required phrase, avoid a claim, or adapt the output to a specific audience segment.
Write short and direct instructions
The best custom prompts are short, clear, and actionable. Instead of writing a long brief, tell moonoo.ai exactly what to change or emphasize. Examples: “make this suitable for B2B founders,” “focus on saving production time,” “avoid exaggerated promises,” or “create a more premium and minimal visual style.”
Do not repeat all brand data
You do not need to paste the entire brand description if the brand is already selected. moonoo.ai uses the existing brand, strategy, and concept context. The custom prompt should add the missing instruction, not replace the whole workflow.
Review the output carefully
After generation, check whether the custom instruction improved the result without harming brand fit, compliance, or channel format.
