Google AI Studio Launches Annotation Mode to Streamline AI App Development

Google AI Studio has introduced a new "annotation mode," a feature designed to simplify the process of editing and refining AI applications. Announced on October 23, 2025, by Ammaar Reshi, Design Lead at Google DeepMind, the update aims to make "vibe coding" more intuitive for developers. The new mode allows users to easily modify elements within their AI apps by directly highlighting components, buttons, or text.

Reshi highlighted the new feature on social media, stating, "> Making edits while you vibe code should be as easy as pointing to the thing you want to change. Introducing annotation mode in AI Studio." This capability leverages the power of Google's Gemini AI to handle the underlying complexities, enabling a more fluid development experience. The goal is to accelerate the iterative process of building and refining AI-powered tools.

Ammaar Reshi, who leads product and design at Google DeepMind, has been a vocal proponent of accessible AI development, often sharing insights into his work with AI tools. "Vibe coding" refers to a rapid prototyping and development methodology used within Google AI Studio, emphasizing quick iteration and intuitive design. This approach allows developers to quickly bring their AI app ideas to life.

The integration of annotation mode into Google AI Studio underscores Google's commitment to enhancing the developer experience and democratizing AI creation. This update, part of broader improvements to the platform, empowers users to build sophisticated AI applications more efficiently. It aligns with Google's strategy to provide intuitive tools that leverage advanced models like Gemini for diverse use cases, from image generation to complex app functionalities.
