AI App Builder

Write a plain-English description of your app, select a framework, and click Build. The AI interprets your requirements and writes the full HTML, CSS, and JavaScript as a single application file. The result loads instantly in the split-view editor so you can read the code on the left and interact with the running app on the right, then describe further changes to keep iterating.

The tool is best suited to self-contained browser apps: calculators, to-do lists, quizzes, games, timers, dashboards, data visualizers, landing pages, forms, and portfolio layouts. Anything that runs entirely in the browser without calling a private backend API is a good candidate. Apps that need a database, server-side authentication, or external APIs requiring secret keys are outside what a purely client-side build can cover.

Four options: Vanilla HTML/CSS/JS for plain projects with no dependencies, Tailwind CSS for utility-class styling without writing custom CSS rules, React loaded from CDN for component-based interfaces, and Vue.js loaded from CDN for reactive single-page apps. All four produce a self-contained file that opens in any browser. Vanilla is the simplest starting point if you are unsure which to pick.

Yes. After the first build, type a follow-up instruction in the refinement field below the editor, such as "add a dark mode toggle" or "replace the list with a card grid," and the AI rewrites the relevant sections. The rest of the code stays as-is. There is no limit on how many refinement rounds you run, so you can shape the app step by step rather than trying to specify everything upfront.

Click "Download ZIP" in the toolbar above the editor. The archive contains your HTML, CSS, and JavaScript as separate files. Unzip it and open index.html in any browser — no install, no server needed. You can also copy individual files from the tab-specific copy button if you want to paste code into an existing project.

The output is clean, structured, and works immediately for prototypes, demos, and simple projects. For anything customer-facing, plan to review the code, add error handling appropriate to your use case, and test across browsers and screen sizes. The code is yours to modify, host, and deploy however you like.

Yes. The generated code carries no licensing restrictions — host it on your own domain, deliver it to a client, or build on it as the foundation for a larger project.

General-purpose chat gives you code snippets you have to assemble yourself. App Builder produces a complete, runnable application with one prompt. The environment includes a split-view editor with live preview, automatic separation of your code into HTML/CSS/JS tabs, one-click ZIP download, and a dedicated refinement field designed specifically for iterating on app builds, not conversations.

Built apps are saved to your account and accessible from the "My Built Apps" panel so you can reopen and continue refining them later. You can delete any saved app at any time. Download a local ZIP copy of anything you want to keep independent of your account.

Describe the layout, key features, and visual style in one clear paragraph. Name specific UI elements and behaviors you want, for example "a dark background, circular emoji buttons, and a running expression display at the top" rather than just "a calculator." Then use the refinement field to add details one step at a time instead of asking for everything in a single massive prompt.
