## Frequently Asked Questions

Q: What is SynthID and how does it work?
A: SynthID is Google DeepMind's watermarking technology that embeds imperceptible digital signatures into AI-generated content. The watermark remains detectable even after modifications like compression, filtering, or cropping. It works across multiple modalities including images, audio, text, and video, allowing verification of AI-generated content without degrading quality or user experience.

Q: Can SynthID detect all AI-generated content?
A: SynthID can only detect content that was originally watermarked with the SynthID technology during generation. It cannot detect AI content created by systems that don't use SynthID watermarking. The technology is primarily used in Google's AI tools like Gemini and Imagen, so content from other AI platforms without SynthID integration will not be detectable by this method.

Q: Is SynthID detection accurate after content editing?
A: Yes, SynthID watermarks are designed to be robust against common modifications. The watermark persists through compression, resizing, color adjustments, and minor edits. However, extreme modifications or complete regeneration of content may reduce detection accuracy. The technology balances imperceptibility with resilience to maintain high detection rates even when content undergoes typical post-processing workflows.

Q: What types of content can SynthID detect?
A: SynthID technology currently supports detection across four main content types: images, audio, text, and video. Each modality uses specialized watermarking techniques optimized for that format. Image watermarks survive visual transformations, audio watermarks resist compression and noise, text watermarks handle paraphrasing, and video watermarks persist through encoding and editing processes.

Q: How do I use a SynthID detector tool?
A: To use a SynthID detector, simply upload the file or paste the content you want to verify. The tool scans for the presence of SynthID watermarks and returns a detection result indicating whether the content was AI-generated with SynthID technology. The process is typically instant for images and text, while audio and video may take slightly longer depending on file size and duration.
