Prototype
Before AI writes a single line of production code, you need to know what you're actually asking it to build. A prototype lets you and anyone else — a co-founder, a friend, a future user — react to something real instead of a description.
What you'll do
- Define your core screens
- Map navigation between screens
- Identify primary actions on each screen
- Walk through your key user journeys end-to-end
- Confirm the core functionality is actually there
Key principle: If you can't click through it, you don't actually know what you're building yet.
Common mistake: Polishing visual design at this stage instead of validating flow and functionality.
