# Using Boolean comparators in a segment

You can use a Boolean comparator to verify if a value is true or is present.

The following table describes Boolean comparators you can use when creating segments:

| **Boolean comparator** | **Description** |
| --- | --- |
| **is True** | Verifies the value is true. |
| **is Null** | Verifies the value is not present. |
| **is False** | Verifies the value is false. |
| **is Not Null** | Verifies the value is present. |
