# Chat with your document without a knowledge base configured
<a name="knowledge-base-chatdoc"></a>

The **Chat with your document** feature in the Amazon Bedrock console allows you to easily test play a knowledge base without the need to configure a knowledge base. You can load a document or drag-and-drop a document in the console chat window to then start asking questions. **Chat with your document** uses your document to answer questions, make an analysis, create a summary, itemize fields in a numbered list, or rewrite content. **Chat with your document** doesn't store your document or its data after use.

**Note**  
The **Chat with your document** feature is currently best supported with Anthropic Sonnet models. See [Supported models for knowledge bases](https://docs.aws.amazon.com/bedrock/latest/userguide/knowledge-base-supported.html) for more information about how to access and use knowledge base models.  
You can't use a reranker model when chatting with your document.

You can also easily prototype a chat or flow application without the need to configure a knowledge base. Using [Amazon Bedrock Studio](https://docs.aws.amazon.com/bedrock/latest/userguide/br-studio.html), you can upload a document from your computer to provide the data or 'data source' for your application. Amazon Bedrock Studio, renamed to Amazon Bedrock IDE, is now available in Amazon SageMaker Unified Studio. For more information, see [Amazon Bedrock IDE](https://docs.aws.amazon.com/sagemaker-unified-studio/latest/userguide/bedrock.html).

To use the **Chat with your document** feature as part of knowledge bases, select the tab below and follow the steps.
