Digitally Stamp Your Writing to Protect Your Ownership From Humans and A.I.

Protect Your Writing

Postmarks are a way to easily and publicly prove and protect your ownership of your digital creations.

• Protect your ownership of books, stories, poems, images, songs, and more.

• Postmark content you have posted to Booksie or content you have not yet released to the public.

• It’s best to Postmark content before you have made it public or immediately after making it public.

• Easily prove you are the owner for any future dispute.

Keeps the file private

Although the proof or ownership is public, Postmarks uses a technology called Zero-knowledge proofs to keep the content of the file private. The file is processed on your browser and never leaves your computer.
