# Introduction

> A2V2.ai lets you build AI agents trained on your own content and embed them anywhere.

A2V2.ai is a platform for building **AI agents** — chatbots that answer questions
using *your* documents, websites, and knowledge instead of generic internet
answers. Upload your content, test the agent, customize how it looks, and drop it
onto your website with a single snippet.

## How A2V2.ai works

Building an agent follows the same loop every time:

<Steps>
  <Step title="Create an agent">
    Each agent is an independent chatbot with its own knowledge, personality,
    and appearance. [Create your first agent →](/building/create-agent)
  </Step>

  <Step title="Add knowledge">
    Upload files, crawl a website, add YouTube videos, or write Q\&A pairs. A2V2.ai
    reads, splits, and indexes your content so the agent can search it.
    [Build the knowledge base →](/knowledge-base/overview)
  </Step>

  <Step title="Shape its behavior">
    Write instructions (the agent's persona and rules), pick a model, and turn on
    skills. [Configure instructions →](/building/instructions)
  </Step>

  <Step title="Test it">
    Chat with your agent in the Sandbox, or compare configurations side-by-side in
    the Playground. [Test your agent →](/testing/sandbox)
  </Step>

  <Step title="Customize & embed">
    Style the widget to match your brand, then add it to your site as a chat
    bubble or an inline iframe. [Embed your agent →](/embed/install)
  </Step>
</Steps>
