# Train the AI with knowledge bases

A knowledge base is a set of documents about your business: product sheets, FAQs, brand guidelines, web pages,
podcasts, videos. When you switch it on, the AI uses that information to write posts that sound like you and get your
facts right.

**You need:** your content as PDF, MP3 or MP4 files, web addresses, or text, and the **Admin** or
**Manage AI Assets** right.

## Create a knowledge base

1. Click **Content → AI Assets** ([open it](https://dash.robopost.app/ai-assets)) and click **Manage** on **Knowledge Base**.
2. Click **New Knowledge Base**.
3. Enter a **Knowledge Base Name**, such as "Products 2026" or "Brand voice."
4. Click **Create Knowledge Base**. The knowledge base opens, with a **Knowledge Base Items** section to fill.

## Add items

In **Knowledge Base Items**, choose the **Item Type**, then:

| Item Type | How to add it |
| --- | --- |
| **File** | Click **Upload pdf, mp4, mp3** and upload the file (up to 500 MB) |
| **Text** | Enter a **Name** and paste the **Text**, then click **Submit** |
| **URL** | Enter a **Name** and the page's **URL**, then click **Submit** |

You see **Item successfully added**, and the item is listed under **Items**. Robopost then reads it in the background:
each page of a PDF, the spoken words of an audio or video file, the text of a web page. Give it a little time before
you use a large file.

To check an item, click the eye button (text and URL items) or the download button (files). Click the trash button to
remove it.

## Use a knowledge base

Wherever you see **Use knowledge base** (or **Use Knowledge Base**), switch it on and pick the knowledge base:

| Where | Guide |
| --- | --- |
| Post ideas: **From Knowledge Base**, or the switch on the other sources | [Post ideas](https://dash.robopost.app/docs/ai/post-ideas.md) |
| The composer's **Compose Text with AI** window | [AI assistant](https://dash.robopost.app/docs/ai/ai-assistant.md) |
| Feed, blog and store automations with **Let AI generate the post text** | [Post from an RSS feed](https://dash.robopost.app/docs/automations/rss-feeds.md#let-ai-write-the-post-text) |
| Faceless video series with the **Custom** or **Product Marketing** content type | [Faceless videos](https://dash.robopost.app/docs/ai/faceless-videos.md) |

The AI combines the knowledge base with your instructions, so say what you want: "Write a post about our return
policy" works better than "Write a post."

## How many documents can a knowledge base hold?

There's no fixed number of items. But for each post, the AI reads only a limited amount of a knowledge base, so a very
large one may not be used in full and can give vaguer results. For the best posts:

- **Keep each knowledge base focused** on one subject.
- **Make several smaller ones**, such as one for products, one for your brand voice and one for FAQs, and pick the one
  that fits each job.
- **Remove outdated items**, so the AI doesn't mix old and new information.

## Rename or delete a knowledge base

Open **Content → AI Assets → Knowledge Base → Manage** ([open it](https://dash.robopost.app/ai-knowledge-bases)) and click **Edit** on the
knowledge base. Change the **Knowledge Base Name** and click **Update Knowledge Base**, or click **Delete** and confirm
to remove it.
