# Defining the author of an annotation

Starting with Nutrient Web SDK 2018.2, the author of an annotation will be saved under the `creatorName` property of an annotation. By default, the `creatorName` for all newly created annotations is set to `null`.

The `creatorName` can be set by the [`Instance#setAnnotationCreatorName`] function:

```js

instance.setAnnotationCreatorName("Alice");

```
