Google makes Gemini's visible AI watermarks optional

- Google added a "Media watermark" setting to Gemini and its AI video generator Flow that lets users remove the visible "sparkle" watermark from AI-generated images, videos, and music.
- Even when toggled off, Google still embeds invisible SynthID and C2PA watermarks into the background of AI-generated content, according to Josh Woodward, VP of Google Labs, Gemini, and AI Studio.
- Removing the visible watermark eliminates the "sparkle" marker in the bottom-right corner of content generated by Nano Banana and Omni models, though users can still ask Gemini or Search to detect invisible markers.
- Google plans to extend the toggle to Search but will withhold it in countries that legally require visible watermarks on AI-generated content.
- OpenAI and Meta already skip visible watermarks — relying on SynthID/C2PA and Meta's proprietary "Content Seal" standard respectively — and Anthropic announced this week it's applying invisible watermarks to both AI-generated text and images.
- The toggle formalizes behavior many users were already doing: editing out the visible sparkle themselves rather than relying on it as a deterrent.
Why it matters: The visible sparkle was never the actual AI-detection mechanism — SynthID and C2PA remain embedded regardless — so the toggle formalizes a cosmetic layer that users were already stripping, while Google aligns its policy with OpenAI and Meta. The geographic carve-out, withholding the toggle in jurisdictions that mandate visible watermarks, turns a UX preference into a compliance variable.
