# Message
The Message labeling tool is used to classify individual messages in [LLM Chat assets](/data/importing-assets/creating-and-importing-llm-chat-assets.md) in the [LLM Chat labeling editor](/labeling/labeling-editor-interface/llm-chat-labeling-editor.md).
{% hint style="info" %}
The Message tool is supported across the LLM Chat labeling editor.
{% endhint %}
## How to add a Message tool to your project
From the project’s *Settings* tab, enter the *Label Set* section.
Click on *Add Category*. From the list that appears, click on *Message*.
A new row will appear named *Message*. Click on it to expand it.
Give your message tool a title.
Enable the *Required* toggle if you want to force labelers to classify at least one message. When the toggle is disabled, labelers will be able to save and move to the next asset without classifying a message using this class.
In order to ask labelers questions about the individual message, for example, if you want to show a further *radio* after placing the message-type class, you must click on *Add Classification* and add a further question. [More on nested questions here](/labeling/labeling-tools/tools/nested-classifications.md).
## How to Label a Message
From the *Tools* section on the left sidebar, select a *Message* labeling tool, then click on the message you would like to classify.
The nested classifications of the class will appear on the right-hand side of the screen. Answer the questions to classify the message.
