Combining Stitch and Anti-Gravity for Autonomous App Creation

Key Concepts:

• Stitch: A free, AI-powered UI design tool capable of generating production-ready interfaces from text prompts. Available as Stitch Solo (browser-based) and Stitch MCP (integrated with Anti-Gravity).
• Anti-Gravity: Google’s agentic AI code editor that can reason, write, refactor, and execute code autonomously.
• Stitch MCP: The connection layer enabling Stitch to work with Anti-Gravity, exposing UI designs, components, and layout structures.
• Agent Skills for Stitch: Reusable behaviors that leverage the Stitch-Anti-Gravity connection, allowing the agent to perform tasks like UI design, code generation, and validation.
• Gemini 3 Pro: A large language model used within Anti-Gravity for reasoning and code generation.
• Remotion: A Stitch skill for creating video content.

1. Introduction & The Power of the Combination

The video highlights the potential of combining Google’s Stitch, an AI-powered UI design tool, with Anti-Gravity, an agentic AI code editor. The combination allows for autonomous app creation – a continuous loop of design, reasoning, building, and verification – resulting in impressive output. Google recently launched Stitch MCP and agent skills for Stitch, facilitating this integration. The presenter emphasizes that this workflow is currently under the radar, offering early adopters a significant advantage.

2. Stitch: Capabilities and Variations

Stitch is presented as a free tool capable of generating clean, production-ready UI designs from simple prompts. It supports web and mobile app interfaces and can export designs to Figma. Two versions are discussed:

• Stitch Solo: A browser-based tool for quick UI mockups. It’s ideal for fast idea generation but requires manual transfer of designs to code editors.
• Stitch MCP (with Anti-Gravity): This integration allows the AI agent to build working code from designs and iterate continuously within the IDE, eliminating manual copy-pasting. This is the preferred method for continuous app development and automated iteration.

3. Setting Up the Workflow: Stitch & Anti-Gravity Integration

The setup process is described as straightforward:

1. Installation: Install Stitch MCP within Anti-Gravity.
2. Agent Skills: Install Stitch agent skills within Anti-Gravity.
3. API Key: Obtain a Stitch API key and paste it into Anti-Gravity.
4. Skill Listing (Optional): Use the command list all available skills in the terminal to view available Stitch skills. Installing these skills (like React component converters, Stitch Loop, and Remotion) enhances output quality.
5. Account Access: Requires a Google account to access both Stitch and Anti-Gravity. Links to download Anti-Gravity for Windows are provided in the video description.

4. Autonomous App Creation: A Demonstration

The presenter demonstrates creating a full autonomous AI dashboard using the combined power of Stitch MCP, Anti-Gravity, and the Gemini 3 Pro model. The process involves:

• Prompting: Providing a prompt to Anti-Gravity.
• Refinement & Design: Stitch refines the idea and generates UI screens.
• Looping & Code Generation: Stitch Loop organizes pages and generates React code.
• Live Preview: The generated app is visible in a live preview within Stitch.
• Backend Coding: Anti-Gravity codes the front-end components generated by Stitch.
• System Design: The agent creates a system design implementation plan, including typography, color palettes, and component documentation.
• App Startup: The app is started using npm rundev within the AI Asian dashboard.

The resulting dashboard features functional components, multiple pages, and animations, demonstrating the rapid development capabilities of the workflow.

5. Visual Design & Iteration with Stitch Canvas

The video also showcases using the Stitch canvas for visual design. Users can:

• Generate Designs: Create designs from prompts (e.g., a luxury modern aesthetic web page inspired by Apple’s 2025 design).
• Multiple Variations: Generate up to five variations of a design.
• Annotation & Iteration: Annotate sections of the design and have the AI agent iterate on them.
• Export to Anti-Gravity: Export designs to Anti-Gravity via zip file download or direct connection through the MCP.
• Further Refinement: Anti-Gravity can then iterate on the designs or code the backend.

6. Utilizing AI Studio

AI Studio is mentioned as another option for connecting to the cloud server and coding backend components.

7. Key Arguments & Perspectives

The presenter argues that the Stitch-Anti-Gravity combination is superior to using Stitch alone because it enables continuous iteration and automated code generation. Stitch Solo is suitable for quick mockups, but Stitch MCP with Anti-Gravity is essential for shipping and continuously improving apps. The presenter emphasizes the autonomy of the workflow, where the AI agent handles design, reasoning, building, and verification in a single loop.

8. Notable Quotes

• “This isn't just designed to code. It's autonomous app creation where your AI agent can design, reason, build, and verify in one continuous loop.”
• “You use the Stitch Solo for fast ideas, but you use the MCP from Stitch with anti-gravity when you actually want to ship an app continuously and iterate on the work automatically with the AI agent.”

9. Data & Statistics

While no specific statistics are provided, the video implies significant time savings and increased efficiency through the automated workflow. The presenter highlights the ability to generate complex landing pages that would typically take developers weeks to create.

10. Conclusion & Takeaways

The combination of Stitch and Anti-Gravity represents a powerful new approach to app development, enabling autonomous creation of beautiful and functional UIs and applications. The workflow is free to use with a Google account and offers significant advantages over traditional methods, particularly for continuous iteration and rapid prototyping. The presenter encourages viewers to explore the tools and join the community to stay updated on the latest AI advancements.
