Capacity is an AI-powered app builder that turns a plain-language description of an idea into a working application. It asks clarifying questions before building, then creates a full app with accounts, payments, and a database, and publishes it online with one click, including support for a custom domain. Users can also export the underlying source code and get ongoing fixes and changes through an AI assistant.
