Techniques that embed machine-detectable markers in text, images, audio or video produced by AI systems so the output can later be identified as synthetic.
Google made SynthID Detector publicly available worldwide in English on October 7, 2026, covering images, video and audio. According to The Neuron, studies find people sometimes rate accurate content as less credible once it is labeled AI-generated.

Google opened SynthID.com to anyone, checking images, video and audio for OpenAI, Nvidia and Kakao watermarks as well as its own. That speeds up flagging partner-made media but cannot vouch for files from outside the SynthID group.

Google opened its SynthID Detector to everyone, checking files for the watermark it has put on more than 180 billion images and videos. Publishing teams get usable evidence from a hit, but the check sees only generators that apply SynthID, so a clean file proves little.

Google DeepMind's SynthID Bio embeds a traceable mark in an AI-designed protein that a detector can find in the physical molecule, without changing how it works. The mark is meant to help DNA synthesis firms screen orders and trace which model made a sequence.

Google DeepMind's SynthIDBio hides a watermark in AI-designed proteins that a detector reads near-perfectly without weakening how they bind. The authors call it a proof of concept, and a determined user can still scrub the mark by rerunning a design through another tool.

Google DeepMind's SynthID Bio watermark matched unwatermarked binders on hit rate, affinity and sequence diversity across three wet-lab targets. The company aims it at DNA synthesis screeners, who could use the signal to auto-clear orders from safeguarded AI models.

Anthropic says it is watermarking Claude text to satisfy the EU AI Act Transparency Code and plans a detection API. The exposure sits with teams shipping generated work as their own.

Anthropic says the mark exists to satisfy the EU AI Act and that it has no durable way to scope it by region, so every customer gets it. OpenAI's support page says text watermarks are coming too.

The EU transparency code about 200 companies signed now has its first live implementation, and experts say it can mark text an employee wrote and Claude merely edited.

Watermarking is already shipping in mainstream models ahead of Europe's compliance date, and the exemptions in the Code of Practice will decide whose writing gets marked, which leaves the absence of a mark saying very little.
