For Android, Build mode outputs production-quality Kotlin with Jetpack Compose, plus an in-browser Android emulator, ADB install, and direct Play Store publishing.

For web apps, it delivers a React frontend and Node.js backend, optional Firebase Firestore and Authentication, and one-click deployment to Google Cloud Run.

Tips for better results include being specific in prompts, using a blueprint, iterating in small steps, reviewing generated code, and exporting to Antigravity for larger projects.

Prerequisites are a Google account and a web browser; publishing Android requires a Google Play Developer account, with no local setup needed.

A project example is a Task Manager with user authentication, task persistence, and AI-powered prioritization suggestions using Gemini.

Generated code is visible in the Code tab and API keys are kept server-side by default for security.

Antigravity Agent handles backend configuration, Firebase setup, and CI/CD-like steps to reduce traditional development toil.

Google AI Studio Build mode lets you turn natural-language prompts into deployable web and Android apps right in the browser, with one-click deployment to Google Cloud.

Current limitations include the web stack defaulting to React/Node.js, Android auth via Firebase may not be supported yet, a free deployment quota, and ongoing migration notes and future paths (Workspace integration, Gemini API upgrades, Antigravity, migration to Android Studio).

Deployment specifics: web apps deploy to Google Cloud Run with a public URL, while Android apps can be published to the Google Play Internal Test Track.

Step-by-step workflow: open Build mode, craft a detailed prompt, review the blueprint, generate code, enable Firebase for auth and database, preview and iterate, deploy the web app, and publish the Android app to the Play Store.
