Google Brings Vibe-Coding Tool Opal to Gemini, Letting Users Build AI Apps Without Code
Opal appears inside the Gems manager and includes a visual editor that breaks app creation into clear, connected steps.
Google is integrating its vibe-coding tool Opal into the Gemini web app, making it easier for users to build AI-powered mini apps directly inside Gemini. The move allows users to create custom apps, known as Gems, using natural language prompts and a visual editor—without writing code.
Introduced in 2024, Gems are customised versions of Gemini designed for specific tasks such as learning, brainstorming, career guidance, coding support, and editing.
With Opal now embedded in the Gemini web experience, users can design their own Gems by simply describing what they want the app to do. Gemini then uses its underlying models to generate the app logic.
Opal appears inside the Gems manager and includes a visual editor that breaks app creation into clear, connected steps. Users can rearrange or link these steps to refine how the app works. Google said the editor also introduces a new Gemini view that converts written prompts into a structured workflow, helping users better understand and modify their apps.
For more advanced customisation, users can switch from Gemini to Opal’s Advanced Editor at opal.google.com. Once created, mini apps can be reused and adapted for different scenarios.
Last month, Google unveiled Antigravity, a next-generation, agent-first coding platform built around its newly released Gemini 3 Pro model.
Designed for the “agent-first era,” Antigravity gives AI agents real power: they can access your editor, terminal, and even a browser, enabling them to independently plan, execute, and verify development tasks.
However, soon after the release, security researchers at PromptArmor uncovered a major vulnerability in Google’s new AI-powered coding tool, Google Antigravity, that allows attackers to exfiltrate credentials and private code — even when standard safeguards are enabled.
