Ep. 250 | Google Just Let Anyone Check If a File Was Made by AI

Google opened its SynthID Detector to everyone on October 7, 2026 — available globally in English. Anyone can check whether an image, video, or audio file carries an invisible AI watermark from Google or partners including OpenAI, NVIDIA, Kakao, and soon Apple. The tool was previously aimed at media professionals. Mike and Frank explain the news in plain English. SynthID is an invisible watermark embedded when AI media is created. A hit means Google or a listed partner stamped the file as made or edited with that AI. A miss is not proof the file is real — Meta uses different tech, open models may add nothing, and watermarks can be stripped. Built-in checks also live in Search, the Gemini app, and Chrome (over 1 million verification requests a day). Google cites over 180 billion images and videos watermarked, plus 240,000 years of audio, since 2023. Shop receipt: suspicious review photo, applicant headshot, competitor ad, supplier scan, or claimed customer audio → sign in → upload to the SynthID Detector (or ask Gemini / Search / Chrome for Google AI marks) → read the result carefully → follow up with a human before you hire, reply, refund, or spend ad dollars. Google did not announce a price; this is an access expansion. Press reports a daily check quota — treat it as a reported limit, not an invented fee. Takeaway: use the checker when trust matters. Do not treat a clean result as a green light, and do not make a personnel or customer accusation on a watermark alone.

Topics: Google · SynthID · Detector · AI watermark · OpenAI · small business --- Frequently Asked Questions What did Google open? The SynthID Detector — a public checker for AI watermarks on image, video, and audio — now available to everyone in English, not only media professionals. What does a positive result mean? A SynthID watermark from Google or a listed partner was found. Google frames results as made or edited with that AI. Follow up with a human before acting. Does a negative result mean the file is real? No. The tool only finds SynthID-family watermarks. Other AI systems may leave no mark. A miss is more context, not proof of authenticity. --- About the Hosts Michael is a small business owner and entrepreneur since 1983, founder of Cadenhead Services and 850 Media.
