Google announced on Tuesday that it is adding a new way to create automated workflows to its vibe-coding app, Opal. The company said a new agent within Opal will allow users to create mini apps that can plan and execute tasks using simple text prompts.
This feature is powered by the Gemini 3 Flash model. It automatically selects the tools needed to complete tasks. For example, it could use Google Sheets to maintain information across sessions, like a shopping list for an e-commerce app. The new agent creates and plans each subsequent step for these tasks independently.
Google stated these agents are natively interactive. If they require more information to proceed, they will ask the user to provide it or offer choices to determine the next steps. The company claims this addition will enable people without technical expertise to build complex workflows within their apps.
The vibe-coding tool Opal was first introduced for users in the United States in July 2025. It allows anyone to create mini web apps or modify existing ones. In October 2025, Google expanded Opal’s availability to 15 more countries, including Canada, India, Japan, South Korea, Vietnam, Indonesia, Brazil, and Singapore. Then in December, Google integrated the tool directly into the Gemini web app, letting users create custom apps through a visual editor without writing any code.
Beyond Google, many other startups are also building tools that let users create apps using natural language prompts. Lovable and Replit are among the more popular ones. Other startups gaining prominence include Wabi, founded by a former Replika founder; Emergent, which is backed by Softbank and Lightspeed; and Accel-backed Rocket.new.
