Google is integrating its vibe-coding tool, Opal, directly into the Gemini web app. This move allows users to build AI-powered mini applications, which Google calls Gems, entirely within Gemini.
Gems are customized versions of the Gemini AI assistant designed for specific purposes. Google offers several pre-made Gems, such as a learning coach, a brainstorming assistant, a career guide, a coding partner, and an editor.
Opal focuses on enabling users to create these mini-apps or combine existing ones. Users simply describe the app they want in natural language, and the tool leverages Gemini’s AI models to build it. Opal is now accessible from the Gems manager within the Gemini web interface.
The tool features a visual editor that outlines the steps required to create an application. Users can rearrange and link these steps together without writing any code. Google highlights that this editor includes a new view that transforms a user’s written prompts into a clear list of steps, simplifying the app-building process and making it easier to understand how the apps function.
For users seeking more advanced customization, there is an option to move from Gemini to the Advanced Editor available on Opal’s dedicated website. Once created, these mini-apps can be saved and reused.
This approach, known as “vibe-coding,” uses AI to program and create applications, a concept that has grown significantly in popularity. The market now includes similar tools from startups like Lovable and Cursor, as well as offerings from major AI providers like Anthropic and OpenAI. There are also consumer-focused tools from companies like Wabi.
The Gemini web app is available online.
