# Managing Data Agent chats
Data Agent chats have a size limit. As you interact with the Data Agent, Fabricate updates the percentage of the size limit that you have used.

As you get closer to the limit, the response time can slow down.
To prevent response time issues, and to keep your chats focused, you can create multiple chats. For example, for a more complex database, you might use different chats to manage different areas of the data.
## Creating a new chat
To start a new chat, at the top of the Data Agent:
1. Click the + icon.
New chat menu
2. From the dropdown:
1. To create a completely new empty chat, select **New Chat**.
2. To create a new chat that starts with a summary of the current chat, select **Summarize and fork**.
## Renaming a chat
To rename a chat:
1. Double-click the chat name.
2. In the field, type the new name.
3. Press Enter.
## Deleting a chat
To delete a chat:
1. Hover over the chat name.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.tonic.ai/fabricate/data-agent-chat/data-agent-db-chat-memory.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
