AI Code Review with Antigravity: Catch Bugs and Security Issues Before They Ship

Why AI Code Review Changes Everything

Code review is essential but time-consuming. According to industry research, developers spend 6-12 hours per week reviewing code. And despite this investment, bugs still slip through—especially security vulnerabilities that require specialized knowledge to catch.

Google Antigravity offers a solution: AI-powered code review that catches issues in seconds. It doesn't replace human reviewers, but it dramatically improves the quality of code before human eyes ever see it.

This guide shows you how to use Antigravity as your first-line code reviewer, catching the issues that waste human reviewer time and the critical bugs that humans miss.

The Three-Layer Review System

Layer 1: Instant Feedback (During Development)

As you write code, Antigravity provides real-time suggestions. This catches issues before you even commit.

Layer 2: Pre-Commit Review (Before Pushing)

Before pushing, run a comprehensive AI review of all changed files. This catches integration issues and ensures consistency.

Layer 3: PR Review (In CI/CD)

Automated AI review as part of your pull request workflow. This provides a consistent baseline review before human reviewers.

Layer 1: Real-Time Code Quality
