Apple's latest software update adds an invisible tag to some photos you edit with its AI tools. The tag comes with iOS 27.2. It is meant to help people tell when a picture was made or changed by AI, even if it looks completely real.

What changed

Starting with iOS 27.2, some Apple Intelligence tools add an invisible watermark called SynthID to images you create or edit. The same applies to iPadOS 27.2, macOS 27.2 and visionOS 27.2, the software for iPad, Mac and Apple Vision Pro. The tag is added in these cases:

  • Image Playground, which creates entirely new images
  • Clean Up, Extend and Spatial Reframing edits in Apple Photos

The second item is the one to notice. Your genuine photos get the tag too if you run them through those tools.

How to check for it

The watermark is invisible. You will not see it on your photos, and neither will anyone else unless they test the image with a SynthID detector. Apple points people to synthid.com, where you can upload an image and see the result.

What is not clear yet

The source does not say whether you can turn the tag off. It also does not say how well the tag holds up if a photo is edited again or shared. Until that is known, assume an AI-edited photo can be identified later.

The takeaway

If you use Clean Up, Extend or Spatial Reframing on a real photo, expect it to carry a hidden AI tag that anyone can check at synthid.com.
