Tell whacka what you want to make — in your own words, like you’d describe it to a friend (“an app where my clients book yoga classes and pick a time”). The AI builds it for you and shows a live preview on the right. The more clearly you describe who it’s for and what it should do, the closer the first version lands.

Just keep talking. Say “make the button blue,” “add a page that lists my customers,” or “the calendar is confusing — simplify it.” Each message updates your app, and the preview refreshes live. There’s no separate “edit mode” — building and changing are the same conversation.

• Say who will use it and what they should be able to do.
• Ask for one thing at a time when you’re refining — it’s easier to get exactly what you want.
• If something looks wrong, describe what you see (“the text is cut off at the top”) so the AI can fix it.
