What's the story

Google has integrated its vibe-coding tool, Opal, into the Gemini web app. The move allows users to create their own custom apps or "Gems," as Google calls them. The integration was announced on Wednesday and is part of Google's continued effort to enhance the capabilities of its AI chatbot. Opal was first introduced in July this year as part of Google Labs and is now available directly within Gemini on the web.

Tool functionality

Opal's role in creating customized AI-powered mini apps

Opal is designed to help users create mini-apps or mix existing ones using natural language descriptions. The tool uses various Gemini models to create the desired app. It can be accessed from the Gems manager of Gemini's web app, where users can find a visual editor that outlines steps needed to create an application without writing any code.

User experience

Enhanced features and customization options with Opal

The visual editor of Opal also offers a new view in Gemini that converts user-written prompts into a list of steps. This feature simplifies the app-building process and gives users an idea of how their apps will work. For more advanced customization, users can switch from Gemini to the Advanced Editor at opal.google.com. The mini apps created through this tool can be reused later, making it a versatile addition to Gemini's capabilities.

Market impact

Opal's integration marks a significant step in AI app development

The integration of Opal into Gemini is a major step in the growing trend of "vibe-coding," or using AI to program and create apps. The market has seen a surge in apps from start-ups like Lovable and Cursor, as well as offerings from AI providers such as Anthropic and OpenAI. With this latest move, Google is further cementing its position in the AI app development space.
