# Create a Knowledge Base

> Give your characters access to your own content so they can answer questions grounded in it.

## What is a knowledge base?

A **knowledge base** is a collection of documents and text that your character can search during a conversation—this is called **RAG** (Retrieval-Augmented Generation).

When a user asks a question, the character looks up the most relevant passages in its knowledge base and uses them to craft a grounded, accurate answer instead of relying solely on what the underlying model "knows."

Typical use cases:

* Product documentation and FAQs
* Internal playbooks and SOPs
* Course material or training content
* Company-specific context (policies, pricing, glossaries)

<Tip>
  Knowledge bases are a great way to keep your character's answers **accurate**, **up to date**, and **on-topic**—without retraining a model.

## Prerequisites

<Warning>
  Knowledge bases are a **premium feature**. You'll need to set up billing before you can create one.
</Warning>

Head to the [Billing page](https://studio.equos.ai/billing) and add a payment method first.

## Create a knowledge base

<Steps>
  <Step title="Open the Knowledge Bases page">
    Go to [studio.equos.ai/knowledge-bases](https://studio.equos.ai/knowledge-bases).
  </Step>

  <Step title="Create a new knowledge base">
    Click the **+** button, give it a name and a short description, then submit.
  </Step>

  <Step title="Add content">
    Open the knowledge base and add:

    * 📄 **Documents** — upload files (PDF, Markdown, text, etc.)
    * ✍️ **Text** — paste content directly for quick notes, snippets, or instructions

    Each item is automatically chunked, embedded, and indexed so your character can search it.
  </Step>
</Steps>

<Note>
  Each knowledge base can hold up to **100 MB** of content. The usage bar on the page shows how much space you've used.
</Note>

## Use it with a character

Once your knowledge base is ready, attach it to any character from the **Knowledge** section of the character editor. From then on, the character will automatically search it during conversations.
