Getting started
Welcome to Master
Master is an AI app builder that turns plain-language prompts into working web apps you can preview, edit, publish and grow.

Master lets individuals and teams build real web applications by describing them in words. You write what you need, Master writes the code, shows a live preview and saves every change as a version you can return to. When your app needs data, sign-in, file uploads, emails or AI, Master Cloud adds a ready backend in one click.
Core concepts
| Concept | What it means |
|---|---|
| Project | One app. It has its own chat, preview, files, versions and Cloud. |
| Chat | Where you talk to Master. Each message can change the app. |
| Version | A saved state of your app after every change. You can restore any of them. |
| Workspace | A team space that owns projects, members, the plan and the credit balance. |
| Credits | The single balance used for building, Cloud and AI in your apps. |
| Cloud | The backend of your app: database, users, storage, secrets, functions, AI and emails. |
