Verify a file
Drop in a file and see what it discloses about its own making: a Made Mark label (read from the file's XMP or ID3 metadata) and C2PA Content Credentials (the cryptographically signed provenance record, read with the open-source CAI toolkit). Made Mark is the human-readable layer; C2PA is the tamper-evident one. Everything runs in your browser — your file never leaves your device.
