This seems to be similar in execution to Google's SynthID. I hope they release actual code the technically proficient can use, unlike SynthID which can only (afaik) be queried with Gemini's UI.

The moment Google announced SynthID, the first domain I bought was deSynthID.com

Several open-source projects have already proven SynthID to be ineffective.
