# Set the category field

Before you categorize your products, you need to select a **category field** in your project. This is the field in your data import that contains your product categories.

The category field is a project-wide field, so if you modify this field, the AI product categorization algorithm will re-run for all channels that have AI product categorization enabled.

{% hint style="info" %}
Tip: Select one category field that can be applied to all channels, rather than using different category fields per channel.
{% endhint %}

Follow these steps to set your project category field:

{% stepper %}
{% step %}

### Go to Categories

Navigate to **\[Your channel] > Categories**.
{% endstep %}

{% step %}

### Click Set Category field

Click **Set Category field**.
{% endstep %}

{% step %}

### Select the field

At **Set category field**, select the field containing the value for your categories (e.g. `product_category`). Channable will automatically suggest the most fitting categories based on your selected field.
{% endstep %}

{% step %}

### Save

Click **Save** to run AI Product Categorization.
{% endstep %}
{% endstepper %}
