Knowledge bases are collections of documents that contain information about your business. You can link them to your agents so they can access this information during conversations and respond more accurately. You can also upload documents, texts, or URLs independently, without assigning them to any knowledge base. These standalone items will appear in the general view and you can organize them into bases later if needed. Access this section from Knowledge Bases in the left sidebar.

​
Overview

The main view shows a table with all documents and knowledge bases in the project. For each entry you can see:
  • Name and size of the document or base
  • Type (file, URL, text, knowledge base)
  • Date created
Use the search bar or the Type filter at the top of the table to find specific documents.

The base will appear in the list and you can add documents to it later.

​
Inside a knowledge base

Click a knowledge base to access its content. Inside you’ll find a table with all documents it contains:
  • Name and size of the document
  • Type (file, URL, text)
  • Date created
From this view you can:
  • Add documents to the base using the button in the upper corner.
  • View the content of a document by clicking on it. Depending on the type, you’ll see the full text, the file to download, or the source URL.
  • Move documents to another knowledge base.
  • Delete documents individually from the base.
When you add a document to a knowledge base that’s already linked to an agent, the document is processed automatically and the agent will have access to the new content once processing is complete.

​
Move items to another base

You can move one or more documents from one knowledge base to another to reorganize your content without having to delete and re-upload files.
1

Select the items

Inside the knowledge base, check the boxes of the documents you want to move.
2

Click Move

In the action bar that appears when selecting items, click Move.
3

Choose the destination base

A modal will open with the list of available knowledge bases in the project. Select the base you want to move the documents to. You can also choose No knowledge base to unlink them from any base.

4

Confirm the move

Click Save. The documents will be moved to the selected base.
If the destination base is linked to an agent, moved documents will be processed automatically and will be available for that agent.

​
Delete a knowledge base

Deleting a knowledge base deletes all documents it contains. This action cannot be undone.
  1. Access the knowledge base you want to delete.
  2. Click the options menu.
  3. Select Delete knowledge base.
  4. Confirm the action in the confirmation modal.
Once created, knowledge bases are linked to agents from each agent’s configuration. You can link the same base to multiple agents and an agent can have multiple linked bases.

Limits

ConceptLimit
Maximum file size10 MB
Number of documentsNo limit
Storage per projectVaries by subscription plan
The total storage available for knowledge bases (RAG Storage) depends on your subscription plan. See the Plans and Pricing page for your plan’s limits.
If you reach your plan’s storage limit, you won’t be able to add new documents until you free up space or upgrade your subscription.

​
Best practices

If the content is less than 500 bytes (approximately a short paragraph), it’s more efficient to include it directly in the agent’s prompt instead of creating a document in a knowledge base. Reserve bases for more extensive content where the agent needs to search for relevant information.
Create separate knowledge bases by area (products, policies, FAQs) instead of one single base with everything. This makes maintenance easier and allows you to link only relevant information to each agent.
Periodically review the content of your bases to ensure the information is current. An agent with outdated information creates a poor experience.
Name your bases and documents clearly (for example, “Return Policy 2025” instead of “Doc1”). This makes management easier when you have multiple bases.
Documents with headings, lists, and well-defined sections are easier for the agent to query than long blocks of unformatted text.

​
FAQ

Yes. A knowledge base can be linked to multiple agents within the same project simultaneously.
The agent will immediately lose access to that document.
Files and URLs cannot be edited directly. If you need to update the information, delete the document and upload a new version.
Processing is usually fast, but depends on the document size.
