Google has recently upgraded its AI-powered mini-app builder, Opal, by introducing an agent-powered step designed to streamline the creation of automated workflows. Using the advanced capabilities of Gemini 3 Flash, this new feature offers developers an autonomous approach to task management, where the agent can plan, reason, and execute tasks on behalf of users. This addition is aimed at simplifying the process for users, who can now create complex mini-apps without extensive technical knowledge.
The agent operates by selecting the appropriate tools and models—such as Web Search or Veo—necessary to achieve the user’s objectives. Instead of developers manually selecting models, Opal’s ‘generate’ step allows them to choose an agent that autonomously carries out this selection, ensuring efficient task execution.
Moreover, the agent supports persistent memory via Google Sheets, maintains dynamic routing to determine subsequent steps, and provides interactive chat functionality to gather any missing information directly from users. This interactive feature ensures that even non-technical users can seamlessly build and manage sophisticated workflows.
Launched in July 2025, Opal has quickly become an integral part of the Gemini web app ecosystem, positioning itself as a competitive alternative to other natural-language app builders like Lovable, Replit, and other emerging solutions. With the addition of these agentic capabilities, Google’s Opal empowers users with a robust toolset to automate workflows and enhances the overall user experience.

Google has upgraded Opal, its AI-powered mini-app builder, with an autonomous agent powered by Gemini 3 Flash. The new 'generate' step lets users delegate tool and model selection—such as Web Search or Veo—to the agent, which plans and executes tasks autonomously. Key features include persistent memory via Google Sheets, dynamic routing between workflow steps, and interactive chat to fill in missing information. Launched in July 2025, Opal positions itself as a competitor to natural-language app builders like Lovable and Replit.
