Opal, Google's tool for building AI-powered mini apps, lands directly in the Gemini web app as an experimental Gem. Can you imagine building small, reusable applications inside Gemini without leaving the environment? Now you can do it from the Gems manager and start designing more personalized experiences for your workflows.
What this integration brings
The integration embeds Opal inside Gemini as an experimental option. That means you'll see a new Gem in your Gems manager that lets you create, edit, and deploy mini apps — those small interaction units that combine prompts, logical steps, and data — without needing external tools.
If you're already familiar with Opal's visual editor, you'll notice a new steps view that turns your prompts into lists of steps. That view makes the flow explicit: each prompt is a step you can reorder, parameterize, or condition. For those who need more control, there's a quick switch to the Advanced Editor at opal.google, where you can tweak finer details of the mini app's behavior.
