# Classify Document

The Classify Document Activity takes a document as input and classifies the document to a predefined label representing a class. The activity takes a classifier definition file and a preprocessed document as the inputs. It outputs a [`ClassificationResult` ](/getting-started/rpa-studio/variables/activity-variables.md#classificationresult)variable which contains the predicted class as the output of the activity.

*see* [*Document Classifier*](/getting-started/rpa-studio/document-ai/document-classifier.md) *for more details on using the activity in a workflow.*

{% hint style="info" %}
