Perché una firma digitale non basta per una foto, un video o una canzone — TrueFile.aiUna firma dimostra che un file non è cambiato. TrueFile risponde a un’altra domanda: è la stessa opera, e chi l’ha dichiarata per primo?TrueFile works like a notary for digital content. It covers images, video, audio and documents, and it is free to start.

A dated record — of who declared a file, and what they declared. Anyone can check it.

Still matches after an edit — a face swap, a crop, a resize, a re-encode, a screenshot — and it reports how much of the original survives.

Nothing is uploaded — the file never leaves your device. Only its fingerprints are sent.

TrueFile reports a modified copy of a file you registered first, and what differs. It never asserts that content is true or false.Home · Use cases · Pricing · llms.txt
