Opal was announced as part of a Google Labs initiative back in July. It lets you build and share mini-apps by combining prompts, models, and tools, all using natural language and visual editing.

Apart from bringing the ability to create mini AI apps directly from Gemini on the web, Google is also giving a boost to Opal’s visual editor. A new view will now convert your prompts into lists of steps when building mini apps, making it easier to edit how your mini apps function.
To access Opal in Gemini on the web, head to the hamburger menu on the top right corner and click on Gems. You should see a list of Gems made by Labs, which are mini apps that have already been created using Opal. You can remix these apps or use the Advanced Editor to create your own version from scratch.
It’s important to note that Opal is not a part of Gemini Apps. This means that the data from using the tool does not appear in your Gemini Apps Activity and is not controlled by Gemini’s Workspace connected app setting.
