The easiest mistake in Deffe is to treat the first prompt like a vague wish instead of a useful brief.
You do not need to write a novel. But you will usually get a noticeably better first result if you tell Deffe what you are building, who it is for and what absolutely needs to be on the site.
What to include in your first prompt
- What the business or project actually is.
- Who the site is meant for.
- Which pages you want first, for example home, services, about and contact.
- What the main goal is, such as leads, bookings, trust or product explanation.
- Any tone or visual direction you want, for example premium, local, playful or minimal.
A better example
Instead of writing build me a nice website for my company, write something closer to this:
Build a clean and trustworthy website for a local accounting firm in Sweden. Start with home, services, about and contact. The main goal is to get consultation requests. Keep the style professional, light and modern, and make the contact form easy to find.
What improves the output even more
- Mention real sections you care about, such as pricing tables, testimonials, FAQ or a map.
- Say what should not happen, for example no heavy animations or no dark theme.
- Feed Deffe real copy, bullet points or service names if you already have them.
- Iterate in smaller steps after the first result instead of trying to solve everything in one giant follow-up prompt.
When to use Pro Builder
If the scope is large, the layout is complex or the build needs to resemble an existing brand closely, Pro Builder is usually the better path. It gives bigger projects more room and avoids cramming too much into a normal first pass.
A good prompt will not magically solve every hard problem, but it often saves a surprising amount of time.
