How to Check if Any Content is AI-Generated Using Google’s Free Tool

Google lately opened its SynthID Detector tool to everyone, allowing anyone to check whether an image, video, or audio file contains AI.

Key points

• DeepSeek V4.1 Flash Gets New Model With Major Coding Gains, Cheaper Agent Tasks.
• Man Sells His Belongings to Meet Dream Woman Only to Find Out She is AI.
• The tool not only works for AI content generated by Google, but additionally by OpenAI, Anthropic, Nvidia, ElevenLabs, and others.
• Google introduced SynthID in 2023 as an invisible watermark embedded in AI-generated content.
• Google first introduced a limited version of the detector for selected researchers and journalists in 2025.

For context, the tool not only works for AI content generated by Google, but additionally by OpenAI, Anthropic, Nvidia, ElevenLabs, and others. These firms apply the same Synth ID to watermark their AI-generated content. Here's how you can employ it to check content yourself.

Man Sells His Belongings to Meet Dream Woman Only to Find Out She is AI. How to Check Content for AI Watermarks. Visit the website: Open SynthID.com to access Google's detection tool. Sign in: Log in using a Google, OpenAI, or Apple account.

Upload your file: Select the image, video, or audio file you want to check.

Check the result: Wait a few seconds for the tool to scan the file and report whether it finds a SynthID watermark.

Meanwhile, the result can support you determine whether the content carries Google's AI watermark. As the tool cannot detect content from every AI system, nevertheless, a file without this watermark is not necessarily human-made. Users are reportedly limited to around 10 checks per day.

DeepSeek V4.1 Flash Gets New Model With Major Coding Gains, Cheaper Agent Tasks. What Can SynthID Detector Find?

Google introduced SynthID in 2023 as an invisible watermark embedded in AI-generated content. Before the detector became publicly available, ordinary users had no direct way to check whether this watermark was present.

Google first introduced a limited version of the detector for selected researchers and journalists in 2025. Its public release now gives everyone a way to check for the watermark without asking Gemini whether something was generated by AI.

For context, the tool can additionally detect SynthID watermarks in AI-generated media from Google's partners, including OpenAI, NVIDIA, and Kakao. Apple additionally participates in SynthID, but backing for detecting Apple-generated content is still being developed. What the Tool Cannot Detect.

SynthID Detector looks for an embedded watermark rather than examining an image or video for visual signs of AI generation. This approach should reduce false positives, but it additionally limits what the tool can identify.

For example, it cannot detect content generated by Meta's AI tools since Meta does not apply SynthID. Content created by other AI systems that do not employ the watermark may additionally go undetected.

Meanwhile, the tool only reports whether it finds a watermark. It does not identify the specific parts of an uploaded file that were generated by AI.

Google notes SynthID watermarks can survive edits produced to AI-generated content after it is created. As the detector reportedly has a daily limit of around 10 checks, nevertheless, users cannot repeatedly test unlimited versions of a file. A Google spokesperson informed Ars Technica that the restriction is intended to stop residents from repeatedly testing modified files to work out how to remove the watermark. Other Ways to Detect AI Content. SynthID is not the only system designed to identify AI-generated content.

OpenAI operates its own detector. It can identify AI-related metadata as well as SynthID watermarks. Meta uses a separate watermark called Content Seal and offers a web-based detector. Nevertheless, a 2026 Reuters report identified that Meta's tool sometimes failed to identify AI-generated content correctly.

Anthropic and Microsoft have additionally kicked off watermarking AI-generated media, but neither at present offers consumer-facing tools for checking those watermarks.

There is still no single detector that can reliably identify content generated by every AI system. While general-purpose AI detectors that analyze content itself can produce unreliable results and sometimes incorrectly label human-created material as AI-generated, most available tools look for specific watermarks or metadata.
