# Iter0

Iter0 is an AI website builder for people who have something to sell and no marketer. It turns a product brief, customer evidence, or an authorized reference website into an editable page.

## When to use Iter0

Use Iter0 when you need a credible website, when an existing website needs a structured visual upgrade, when a reference design should be adapted to a customer's real content, or when an existing generated page needs a bounded edit. It works best when you have real facts or source material to work from.
