# What is Decimal?

> Decimal is an AI support agent that investigates and resolves customer issues using your codebase, knowledge base, and connected tools.

Decimal is an AI support agent that resolves complex customer issues in minutes. It investigates tickets by searching your codebase, knowledge base, logs, and connected tools — then produces both a technical analysis for your team and a customer-facing response.

## How It Works

<Steps>
  <Step title="Connect your tools">
    Link your code repositories, ticketing systems, observability platforms, and knowledge sources. The more context Decimal has, the better it resolves issues.
  </Step>

  <Step title="Tickets come in">
    Tickets flow in from your connected ticketing integrations (Zendesk, Intercom, Plain, Pylon, and others) or through a chat widget embedded on your site.
  </Step>

  <Step title="AI investigates">
    The agent searches your codebase, queries logs and metrics, and references knowledge base articles to understand the issue and identify a resolution.
  </Step>

  <Step title="Response delivered">
    Decimal produces a detailed **investigation** for your team and a **customer-facing response** ready to send — with full source citations.
  </Step>
</Steps>
