# What is Circuit?

> Circuit turns your technical documentation into an intelligent engine that guides your team through complex quoting, field work, and troubleshooting. Purpose-built AI for manufacturing and service organizations.

Circuit stores your documents in searchable **indexes**, then lets you build **agents** that can reason over that knowledge and answer questions in natural language. Your team interacts with agents through a **chat** interface, either inside the Circuit app or embedded directly on your website.

## How it works

<Steps>
  <Step title="Organize your knowledge">
    Upload documents to **indexes**: structured containers that hold PDFs, Word files, spreadsheets, presentations, and more. Circuit processes and indexes the content automatically.
  </Step>

  <Step title="Configure an agent">
    Create an **agent** and point it at one or more indexes. Choose a domain template (field enablement, customer service, RFP, and others) or start from scratch.
  </Step>

  <Step title="Start asking questions">
    Your team chats with the agent in natural language. The agent searches your documents, reasons over the results, and responds with answers that cite their sources.
  </Step>

  <Step title="Improve over time">
    Users provide feedback with thumbs up and thumbs down buttons. Administrators review feedback and refine indexes and agent configuration to improve answer quality.
  </Step>
</Steps>
