# Knowledge Base Overview

> Organize documents and enable AI-powered search across your organization's knowledge.

The Knowledge Base allows you to upload, organize, and search documents using AI-powered semantic search. Documents in your Knowledge Base can be accessed by Stella AI to provide accurate, context-aware responses.

### Key Concepts

<CardGroup cols={2}>
  <Card title="Datasets" icon="folder">
    Collections that organize related documents together. Each dataset can have its own configuration and access settings.
  </Card>

  <Card title="Documents" icon="file">
    Individual files uploaded to datasets. Supported formats include PDF, Word, text, and markdown files.
  </Card>

  <Card title="Stella Search" icon="sparkles">
    Enable AI-powered search on datasets to make them available to Stella AI agents.
  </Card>

  <Card title="Connected Sources" icon="link">
    Import documents automatically from external sources like Intercom Help Centers.

### How AI Search Works

When you enable "Searchable in Stella" on a dataset:

1. **Document Processing**: Each document is automatically chunked into semantic segments
2. **Embedding Generation**: Segments are converted to vector embeddings using AI
3. **Indexing**: Embeddings are stored for fast similarity search
4. **Search**: Stella can find relevant content by meaning, not just keywords

<Note>
  Processing happens automatically in the background. Large documents may take a few minutes to become searchable.
</Note>

### Getting Started

<Steps>
  <Step title="Create a Dataset">
    Go to Knowledge Base and click **Add Dataset**. Give it a name and optional description.
  </Step>

  <Step title="Upload Documents">
    Open your dataset and click **Upload Documents**. Drag and drop files or browse to select.
  </Step>

  <Step title="Enable Stella Search">
    Edit your dataset settings and toggle **Searchable in Stella** to make documents available to AI.
  </Step>

  <Step title="Use with Stella">
    Stella AI will automatically search enabled datasets when answering questions or performing tasks.
  </Step>
