AI will lead a natural conversation — asking about the business, languages, payments, design style — and then build everything automatically. The entire process takes a few minutes.

TIP

The installer asks about your AI subscription plans during setup. If you have Claude Max (unlimited), it will prefer Claude for all tasks since there's no cost concern. Learn more about AI routing.
