Overview

This video introduces and demonstrates Antigravity, a new agentic development platform from Google DeepMind. The presenter explains its core design principles (autonomy, trust verification, agent-first paradigm), showcases its features through a live demo of building a NextJS app, and discusses how it differs from traditional IDEs and similar tools like Cursor.

Key takeaways

• Google DeepMind's Entry into IDEs: Google acquired the team behind Windsurf for $2.4 billion and they have now released their first product, Antigravity, an agentic development platform.
• Core Design Principles: Antigravity is built on three pillars: autonomy (enabling asynchronous work locally), trust and verification (agents create artifacts for self-improvement and review), and an agent-first paradigm (prioritizing agent-driven development before manual intervention).
• Key Features and Interfaces: The platform includes a VS Code-like editor, an Agent Manager for creating and launching agents, and an integrated browser that agents can use for testing and information gathering.
• Artifacts and Workflow: Agents create artifacts like implementation plans and task lists to guide development. Users can provide feedback and edit plans on the fly. A "walkthrough" feature provides a read-me of the agent's actions.
• Integration and Customization: Antigravity supports multiple AI models (Gemini, Claude) and allows integration with existing VS Code settings. Users can also provide feedback on generated code and screenshots.
• Future Outlook: While currently free, future paid tiers are anticipated as more advanced models like Gemini 3 roll out.
