You can create [user-defined segments](https://www.infobip.com/docs/customer-profiles/segments/segment-types#user-defined-segments) **manually** by defining specific rules or **use AI** to generate segment criteria automatically. After creating segments, you can [manage](https://www.infobip.com/docs/customer-profiles/segments/manage-segments) or [add them to communication](https://www.infobip.com/docs/customer-profiles/segments/add-segment-to-communication).

## Create a segment manually

1. Go to **Customer Profiles** → **Segments**.
2. Select **Create segment**.
3. In the **Set segment rules** section, define the criteria for profiles to be added to the segment. You can specify attributes, events, or both:
   - **Attribute** - Add the attribute, the relevant attribute operator, and the attribute value. To add multiple values for an attribute, use the `OR` and `OR LIST` operators. To add multiple attributes, use the AND and OR operators. You can add a **maximum of 25 clauses** for attributes.
   - **Event** - Add the event, the relevant event operators, event values, and properties. To add multiple events, use the `AND` operator. You can add a **maximum of 5 clauses** for events.

   You can search for attributes and events, or use filters. At the top of the page, you can see an overview of the profiles that match the criteria.

4. Add a name for the segment.
5. In the **Segment summary** section, add a description for the segment.
6. Alternatively, you can generate the summary by using AI. Select **Generate AI summary**.
7. Select **Save**.

Note
If you use list attributes, you can control how the segment rules apply to list attributes. For more information, see [Filter list items](https://www.infobip.com/docs/automation-studio/journeys/using-lists#filter-list-items).
