Content Seal and Meta's detector
Meta launched a detector alongside Muse Image at meta.ai/identification. It is a preview, it only recognizes Muse Image output, and it does not read SynthID or C2PA, so it cannot check images from Google or OpenAI. Content Seal is not interoperable with those systems.
Labels on Instagram and Facebook
Meta labels content as “AI info” when it detects industry-standard AI signals or when you disclose AI use. Since September 2024, images that were only edited with AI show the label in the post menu rather than on the image. Images from Meta's own tools are identified by Meta directly.
What cleaning changes
Cleaning removes any IPTC or other metadata in the file you saved. It does not remove Content Seal, so Meta can still identify a Muse image after cleaning.
