# Introduction

> Ito is an AI-powered QA agent that tests your app on every pull request — no test scripts required.

Ito is your automated QA engineer. It installs as a GitHub App, watches your pull requests, and runs real browser-based tests on every PR — then posts a detailed bug report as a comment, complete with video recordings, reproduction steps, and code analysis.

You don't write tests. You don't maintain a test suite. You connect a repository and Ito starts working on the next pull request you open.

## What Ito does

<CardGroup cols={2}>
  <Card title="Tests every PR automatically" icon="robot">
    When a pull request is opened or updated, Ito provisions an isolated test environment and runs an AI agent that explores your app in a real browser.
  </Card>

  <Card title="Reports bugs directly on the PR" icon="comment">
    Ito posts a comment on the pull request with bug reports, severity ratings, and reproduction steps — so reviewers have context without leaving GitHub.
  </Card>

  <Card title="Records every session" icon="video">
    Each test run is captured as a video. In the dashboard, the video seeks to the exact moment a bug occurred.
  </Card>

  <Card title="Analyzes relevant code" icon="code">
    For each bug, Ito identifies the files and line ranges in your codebase that are likely responsible.
  </Card>

  <Card title="Classifies bugs by severity" icon="triangle-exclamation">
    Every finding is rated Critical, High, Medium, or Low so you can prioritize fixes before merging.
  </Card>

  <Card title="Tracks bug detection over time" icon="chart-line">
    The dashboard shows PRs tested, bugs found by severity, and your bug detection rate across any time period.
