# PR Reviews

> PlayerZero automates PR reviews, testing guidance, and regression detection, enabling faster, higher-quality code delivery.

## What Is PR Reviews & Code Analysis?

PlayerZero integrates with your repositories to analyze every Pull Request (PR), posting actionable summaries and insights as comments. It helps teams understand code changes, test effectively, and catch regressions before they reach production.

<Note>
  Any team member with **viewer** access or higher can start a PR review session. No special permissions are required.

## Automatic Monitors on Merge

When a PR is merged, PlayerZero can automatically generate regression monitors that watch for issues introduced by the merged changes. These monitors target existing telemetry signals and are posted as a comment on the merged PR.

For details on how proactive monitors work and how to manage them, see [Monitors → Proactive Monitors](/features/monitors#proactive-monitors).
