Copyright01 is an online service that helps creators document the existence and date of their digital work. Its platform offers a simple deposit process: users create an account, upload a file or provide a web address, and receive an instant PDF certificate with a QR code for public verification. Each deposit includes a SHA-256 fingerprint and electronic timestamp, while entries can also appear in a public register.

The service supports a wide range of creative materials, including text, images, music, video, documents, archives, websites, source code, GitHub repositories, and social media content. A dashboard lets users manage deposits, retrieve certificates, and track storage and credits. Copyright01 describes its files as protected with AES-256 encryption and double backups, and says its service complies with GDPR requirements.

Creators can start with three free deposits, including downloadable certificates and 250 MB of storage. Paid options include credit packs and a monthly or annual subscription, with higher storage and file limits.
