# Gen AI Components

Gen AI components allow you to build intelligent automation blocks powered by AI. They use prompts, knowledge bases, and tools to generate, evaluate, or extract information from conversations.

### AI Agent

The **AI Agent block** creates a dedicated AI agent within a workflow.

* **One agent per workflow** is allowed.
* The agent is the **core driver** of automation, responsible for handling logic and conversations.
* Agents can:
  * **Call tools** (e.g., APIs, functions)
  * **Generate replies** for customers
  * **Fetch information** from the knowledge base

<Tip>
  Define clear **instructions and goals** for each AI agent to avoid overlap or misrouting across workflows.

### Generate

The **Generate block** uses AI to create content or validate responses.\
Common uses:

* Generate a **reply** based on inputs and KB context
* **Evaluate** if a user’s query has been fully answered
* Summarize long responses into concise answers
* Provide **alternatives** when one reply is insufficient

***

### Extract

The **Extract block** uses AI to pull structured details out of user queries, similar to **Capture**, but more flexible.\
Examples:

* Extracting an **order ID** from a free-form message
* Pulling a **date** or **location** from a user’s text
* Identifying **entities** like product names or account numbers

<Note>
  Use **Extract** when inputs are **unstructured or varied**. Use **Capture** when the format is **predictable** (e.g., fixed ID patterns).
