Which AI Tools Use SynthID?

Independent information site. Not affiliated with or endorsed by Google. The official detector is at synthid.com.

As of October 10, 2026, SynthID is used by Google's own AI tools and by partners OpenAI, NVIDIA and Kakao. Apple is announced, and ElevenLabs has been named as committing. Those are the companies whose media the public SynthID Detector is set up to recognize. Content from anyone else can come back clean even when it is AI-made.

Who uses SynthID

Company	What gets marked	Status	Source
Google	Gemini text in the app and on the web, plus media from Imagen, Veo and Lyria, and podcast audio from NotebookLM	Live	Google DeepMind, Google blog
OpenAI	Images from ChatGPT, Codex and the API. The Next Web says OpenAI's verification page also checks audio	Live, announced May 2026	PetaPixel, The Next Web
NVIDIA	Videos from the Cosmos preview microservice on build.nvidia.com	Partnership described in Google's May 2025 post	Google blog
Kakao	Its Kanana models. Image model Kanana-Kollage and video model Kanana-Kinema from the second half of 2026, starting with the Kanana Template video feature in KakaoTalk	Announced May 20, 2026. Watermarking starts in the second half of 2026	Kakao press release
Apple	Images created and edited with Apple Intelligence	Announced as "coming soon", no date	Engadget, Google
ElevenLabs	Audio	Named as having committed to add SynthID. Not listed among the detector's current partners	Engadget

GetReal Security isn't a generator. Google announced it as a content-verification partner so that detection can reach beyond Google's own tools.

Who doesn't use it, as far as we can tell

Meta and Microsoft. TBreak reports they use their own watermarking systems.
Open models run on home hardware. TBreak notes these often add no label at all.
Midjourney, Stable Diffusion and others. We found no source naming them as SynthID partners. That is not the same as proof they don't mark their output, so test a file instead of assuming.

What "covered" does and doesn't mean

Not every file. A partner adopting SynthID doesn't mean every output carries the mark. Older content made before adoption may not.
Not every medium. Kakao's announcement covers images and video, and OpenAI's coverage focuses on images. Text watermarking is Google's, for Gemini.
Not forever. Partner lists change, and announced plans slip.

How to check whether a tool is covered

Look at the partner logos on synthid.com.
Generate a file yourself with that tool and run it through the detector.
Read the company's own announcement and note the date.
Remember a clean result on your test file only tells you about that file.
