Google's Secret AI Coding Tool Explained In 5 Minutes

Google has quietly released one of the most effective AI coding tools available, yet it remains largely unknown. It's completely free, remarkably powerful, and performs with incredible efficiency.

A Hidden Gem in Google's AI Suite

Google offers a wide array of AI and Gemini products, each introducing impressive functionalities. Tools like Firebase Studio, their official vibe coding platform, and the Gemini Canvas for creating small artifacts are well-known. Additionally, there are specialized tools like Jewels and Stitch, contributing to a large ecosystem of applications, many of which have overlapping features and are often free.

Among these, a particularly powerful tool is hidden within the Google AI Studio. This is the same platform where you can access all Gemini models without limitations. Inside AI Studio, a revamped vibe coding tool has been significantly upgraded, transforming it into a full-fledged AI code editor that runs directly in your browser. To access it, simply navigate to the Build section of AI Studio.

This coder is designed to help you build applications using the Gemini API, but you can use it to create anything, including apps that don't incorporate AI at all. You can explore a variety of community-built examples or view your own creations and recent projects under the "Your Apps" section.

How It Works: Building an Application

At the top of the interface, a prompt box allows you to describe what you want to build. You can even attach images, PDFs, mockups, or other files to provide additional context.

Let's walk through an example. We can ask it to build an image cropper tool.

After you submit the prompt, a sleek interface opens, and the AI begins to outline the necessary steps. It generates the code primarily in React and demonstrates one of its most impressive features: the ability to create a complete file and folder structure, not just a single script. The output is usable, downloadable, and real code.

Advanced Features and Customization

The platform provides a comprehensive development environment right in your browser.

Key Features: * In-Browser IDE: You can manually edit the code directly. The interface includes a file tree, a clean design, and a behavior-aware code editor. * Automated Error Handling: If an error occurs, the system detects the issue and provides a one-click "autofix" button to resolve it. * Checkpointing: The tool saves checkpoints of your progress, allowing you to see what was changed at each step and roll back to a previous version if needed. * Full Project Control: You can create custom files and folders or upload your own. A console log and a preview panel are also available, and you can share your project with a link. * Export and Reuse: The entire project can be downloaded as a ZIP file for local editing. You can also create a copy to experiment with different variations.

The user interface is exceptionally well-designed—clean, minimal, and powerful without unnecessary clutter.

Intelligent and Iterative Development

Let's take the customization further. Suppose you want to change the color scheme. You can simply type your change into the prompt box, for instance: "make the colors red."

The tool processes the change intelligently. Instead of rewriting entire files, it uses smart diffing patterns to edit only the necessary code blocks. This approach is significantly faster and cleaner. Once the changes are applied, you can continue building or download the updated project. All modifications are saved, so you can return later and pick up where you left off.

You can also reset the conversation if it becomes cluttered or hide panels like the assistant, code editor, or preview to customize your workspace. Just remember to save your project after each significant step to ensure your shareable links are up-to-date.

Why This Tool Stands Out

This coder is a criminally underrated tool. Following its silent upgrade, it has emerged as one of the most powerful free AI coding solutions available. It is completely free and offers unlimited use. Whether you want to integrate Gemini into your applications or build non-AI tools, the choice is yours. Give it a try and see what you can build with it.
