Google is bringing its vibe-coding tool, Opal, into Gemini, making it easier than ever to create AI-powered mini apps directly from the Gemini web app. With this integration, users can build custom apps inside Gemini using Google’s “Gems” system—essentially personalized versions of Gemini designed to handle specific tasks, workflows, or scenarios.
Gems first launched in 2024 as tailored Gemini experiences that help people get things done faster. Google already offers several ready-to-use options, including a learning coach, brainstorming assistant, career guide, coding partner, and editor. The big idea is simple: instead of using one general-purpose chatbot for everything, you can create (or pick) a specialized assistant that behaves the way you want for a particular goal.
Opal takes that concept a step further by letting users create mini apps—or combine and remix existing ones—using everyday language. Rather than writing code, you describe what you want the app to do, and Opal uses Gemini models to generate the app’s logic for you. This style of building with prompts, often called vibe-coding, has surged in popularity as more people look for faster ways to prototype ideas, automate tasks, and turn concepts into working tools without traditional development work.
With Opal now available directly in Gemini on the web, you can find it inside the Gems manager. It comes with a visual editor that lays out the app-building process as a series of steps. Users can drag, rearrange, and connect these steps to shape how the mini app works—all without needing to write code. This visual approach is designed to make app creation more approachable, while also letting users clearly see the workflow behind what they’re building.
Google is also adding a helpful new view within Gemini that turns your written prompt into an organized list of steps. In practice, that means you can describe an app in plain English, then immediately see how Gemini interprets it as a workflow—making it easier to understand, refine, and troubleshoot your mini app as you build.
For users who want deeper control and more advanced customization, Google says it’s possible to move from Gemini into Opal’s Advanced Editor at opal.google.com. Once created, these mini apps can be reused, making it easier to build a personal library of tools for repeat tasks—whether that’s drafting, planning, summarizing information, or streamlining everyday workflows.
This Opal-to-Gemini integration also lands at a time when AI app-building is expanding quickly. Over the past couple of years, vibe-coding has become a major trend, with more tools emerging for both developers and everyday consumers who want to build useful apps through prompting and visual workflows.
Gemini’s web app is available at gemini.google.com.
