# Overview - What is Greptile?

Greptile is an AI code review agent that automatically reviews every pull request with complete understanding of your codebase. Unlike traditional linters that check files in isolation, Greptile builds a graph of your entire repository to understand how changes affect the whole system.

## How it works

1. **Connects to your repository**  
   Install the GitHub/GitLab app and select repos. Greptile builds a complete graph of your codebase - every function, class, and dependency.

2. **Reviews PRs automatically**  
   On every pull request, Greptile analyzes changes with full context. Posts findings in ~3 minutes as PR comments with suggested fixes.

3. **Fix with one click**  
   Every review comment includes a **Fix with your Agent** button that sends the issue — with file paths, line numbers, and suggested code — straight to Claude Code, Codex, Conductor, Cursor, or Devin. A **Fix All** button in the review summary sends every issue at once. [Learn more about Fix with your Agent →](https://www.greptile.com/docs/integrations/fix-with-your-agent)

4. **Learns from your team**  
   Your 👍/👎 reactions and replies teach Greptile what matters. After 2-3 weeks, it stops commenting on things you don’t care about.
