    ZkPaper – Untraceable Document Editor with Proof of Authorship▲6

    Hi! I made this as a hackathon project, the result is really cool and works very well. All you need to do is connect with your Metamask wallet and start creating documents. It also has proof of autorship, so we know if you wrote the document, or you just copy/pasted from chatgpt. This could be useful for schools or something. Let me know what you think. Thanks!
