Google Opal: Google Labs has officially introduced Opal, an experimental tool designed to empower users to build simple AI mini applications without the need for traditional coding. This innovative offering, part of Google Labs’ broader initiative to explore the future of building with AI models and prompts, made its public beta debut on July 24, 2025, and is currently available to users exclusively in the United States.

Embracing the “Vibe-Coding” Revolution
Opal joins a growing trend of “vibe-coding” tools, where companies are creating solutions that allow non-technical individuals to prototype applications without writing code. Google’s entry into this space with Opal demonstrates its commitment to making AI application development more accessible and intuitive for a wider audience, moving beyond just professional developers.
No Code, More Flow: How Google Opal Works
At its core, Opal is an AI-powered development tool for building and remixing AI mini apps. It stands out by enabling users to bring prompts to life with no code required. The process typically begins with a ChatGPT-like chatbot interface, where users describe the task their application should perform using conversational natural language commands. Users can also provide additional data or connect external tools as needed.
Google Opal then leverages this input to automatically generate a simple application. A key feature is its ability to build multi-step apps by chaining together prompts, AI model calls, and other tools. As Google product manager Elle Zadina explains, Opal “converts your app description into a multi-step workflow with inputs, generation steps and output steps”.
For those who want more control, Google Opal provides a visual editor. This editor represents the application as a collection of cards on a virtual canvas, illustrating inputs and processing steps. Users can click into any step to see the underlying prompt or instructions and edit them directly. The visual editor allows for fine-grained control without needing to review a line of code, enabling users to tweak a step’s prompt, add new features, or call a tool. You can also manually add steps from Opal’s toolbar.
Once an application is ready, it can be immediately shared on a personal Google account through a simple sharing link, similar to how Google Docs links are used.
Powering Your Productivity: Use Cases and Pre-built Apps
Opal is designed to accelerate the prototyping of AI ideas and workflows, demonstrate a proof of concept, or build custom AI applications to boost productivity. On launch, Google Opal includes a demo gallery with starter templates that can be used as-is or remixed to fit specific needs.
The tool comes with over half-a-dozen prebuilt applications, which span various practical use cases:
- Consumer use cases, such as designing video games.
- Business tasks, including generating marketing materials and researching products. An example use case highlights the ability to link multiple data processing steps, such as having an application generate a product description and then create a promotional video based on that description.
Under the Hood: The AI Driving Opal
While Google has not specified the exact algorithms used, Opal relies on multiple AI models to generate applications. One strong candidate is Google’s recently introduced Gemini 2.5 Pro large language model, which is known for its adeptness at application development tasks and has set a record on the LMArena benchmark for coding skills. For simple applications, a less capable but more power-efficient coding model might be used. Additionally, Opal’s clip generation features are presumably based on one of Google’s Veo video algorithms.
Opal is currently accessible through Google Labs, a dedicated webpage that showcases more than two dozen of the search giant’s experimental AI products, ranging from web search automation to application interface design. This public beta is an exciting step towards a future where building with AI is accessible to everyone.
