              <p>
                Images are generated using a hosted model and AI disclosure is
                added to the file. This information, referred to as Content
                Credentials, serves as a nutrition label for the content. We
                employ the tamper-evident open C2PA standard, which utilizes PKI
                and is resistant to forgery. You can download and transfer the
                image to supported editing tools like Photoshop, where your edit
                history can also be securely added to the file. This historical
                information, known as provenance, accompanies your media and can
                be extracted and displayed using a tool or website.

              <p>
                Images are generated using a hosted model and AI disclosure is
                added to the file. This information, referred to as Content
                Credentials, serves as a nutrition label for the content. We
                employ the tamper-evident open C2PA standard, which utilizes PKI
                and is resistant to forgery. You can download and transfer the
                image to supported editing tools like Photoshop, where your edit
                history can also be securely added to the file. This historical
                information, known as provenance, accompanies your media and can
                be extracted and displayed using a tool or website.
