How to have a great conversation with Marnix and get the best results.
Talking to Marnix

What Marnix listens for
Marnix is trained to extract the specifics that matter for building: what the app does, who uses it, what it looks like, and how the user flows through it. You don't need to use technical language — just describe your vision as if you're pitching it to a designer.
Tips for great voice prompts
- Mention the visual style. Dark or light theme, colors, mood (minimal, bold, playful). These details make a big difference.
- Describe the user experience. Walk through what someone does when they open the app. What's the first screen? What's the main action?
- Name the key screens. "A home feed, a profile page, and a settings screen" is much clearer than "the usual pages".
- Don't worry about the tech. You don't need to say "React" or "Supabase". Marnix handles all technical decisions. Just describe what you want.
- Answer Marnix's questions. When Marnix asks for clarification, that's a good sign — it means the app will be more accurate. Take 10 seconds to answer well.
Prompt quality examples
⚠ Vague — hard to build from
"Build me a fitness app."
Good — clear purpose
"Build me a workout tracker where I can log exercises, sets, and reps. I want to see my history by week."
Great — specific and visual
"Build me a workout tracker. Dark background with orange accents. Three main screens: a home screen that shows today's planned workout and a motivational quote, a logging screen where I tap to add exercises with sets and reps, and a history view that shows the last 30 days in a calendar grid. Minimal and clean — no clutter."
