Want to build your own small AI tool, like a travel planner, a blog idea generator or a study helper, without writing code? Google Opal lets you describe the app in plain English and turns it into a working AI mini-app you can use and share.
Here’s what Opal is, how it works, what you can build, and its limits.
What Is Google Opal?
Opal is a free experiment from Google Labs for building AI-powered mini-apps without code. It launched in the US in July 2025 and later expanded to more than 160 countries. You describe what you want, and Opal creates a step-by-step workflow that uses Google’s AI models to produce the result.
Note: Release dates and rollout timing can change. Please confirm the latest details on the official website or help center.
How Opal Works
- Describe your app. For example: “Ask for a city and travel dates, then create a 3-day itinerary with a packing list.”
- Opal builds a workflow. It turns your idea into connected steps: inputs, AI steps and outputs.
- Edit in plain English or visually. Change steps by chatting, or adjust them in the visual editor.
- Test and debug. Run the app step by step to see exactly where something goes wrong.
- Share it. Send a link so others can use your mini-app with their Google account.
What Can You Build?
- Personal helpers: trip planners, recipe finders, workout ideas.
- Content tools: blog outlines, social captions, product descriptions.
- Study aids: quiz makers, topic explainers, flashcard generators.
- Small business tools: customer reply drafts, simple research reports.
Opal is best for small, focused tools. It isn’t designed for full websites with user accounts and databases.
Is Google Opal Free?
As a Google Labs experiment, Opal is currently free to use with a Google account. Experiments can change, add limits or be shut down, so don’t build anything business-critical on it without a backup plan. Check Google Labs for the latest availability.
