What is Bolt AI Builder?

Bolt is an AI-powered website and app builder that lets you create full-stack projects by chatting with AI. It generates, tests, refactors, and iterates on code automatically, reducing errors so you can focus on your vision. Bolt Cloud provides built-in hosting, databases, authentication, and SEO, giving you enterprise-grade infrastructure in one interface.

How to use Bolt AI Builder?

Sign in or get started for free, then describe what you want to build in the chat prompt (e.g., 'Let's build a prototype...'). Choose a starting point such as Website, Slides, App, Prototype, or a template, or import from Figma or GitHub. Bolt generates the code, which you can refine through further prompts, and then deploy using built-in hosting with custom domains and analytics.
