 **TinyMCE AI** includes the following improvements and fixes and additions.
 
+==== The TinyMCE AI plugin now adds an `ai` property to the `SetContent` and `BeforeSetContent` event payloads
+// #TINYMCE-14302
+
+Previously, the **TinyMCE AI** plugin set content into the editor without marking it as AI-generated. Integrations that listen to the `+BeforeSetContent+` and `+SetContent+` events had no reliable way to distinguish this content from content set by other sources, and could not apply origin-specific processing, tracking, or analytics.
+
+In {productname} {release-version}, the **TinyMCE AI** plugin adds an `+ai+` property to the `+BeforeSetContent+` and `+SetContent+` event payloads when it sets content. Event handlers can check this property to detect **TinyMCE AI**-generated content and respond based on its origin.
