You made it. Now prove it.
I have a love-hate relationship with AI. I love using it to help me build apps and websites, develop and test ideas and proofread blogs etc.
But! Something that has bothered me for a while, and should bother a lot more people than it seems to, is that every major AI model was trained on human-created content. Articles, blog posts, novels, code, poems, essays — all hoovered up from the internet and fed into systems that can now produce passable imitations of the real thing.
The people who created that content got nothing. No attribution. No compensation. No acknowledgement that their work was used at all.
And there's currently no way to prove it. If an AI produces something that draws on your work, you can't demonstrate that connection. You can't even prove you wrote the original in the first place — not in any way that's cryptographically verifiable, timestamped, and independent of a platform that might disappear tomorrow.
So, with the help of AI, I'm building something that might address the problem of AI.
What I'm trying to build
Keep Digital Human is a provenance tool for creators. That's a fancy way of saying that it lets you prove you made something, and when.
You paste your text or file into a form in your browser, and without any of your data being sent anywhere, the system creates a cryptographic fingerprint of your content. A SHA-256 hash, if you want the technical term. It's a unique string of characters that can only be produced by that exact piece of text or file. Change a single comma or pixel and you'd get a completely different fingerprint.
That fingerprint gets timestamped and stored. The original content never leaves your browser. We never see it. We never store it. All the system keeps is the fingerprint, the timestamp, and your identity.
You then get a public verification page — a URL you can share with anyone — that proves this specific content existed at this specific time, authored by you.
Why this matters
Think of it as a digital deed of authorship.
Right now, if you publish a blog post, the only proof you wrote it is... that it's on your blog. If someone copies it, or an AI ingests it, or it appears in a training dataset — what evidence do you have? A WordPress timestamp that you could have faked? A screenshot that proves nothing?
A cryptographic fingerprint is different. It's mathematical proof. You can independently verify it. You can't forge it. You can't backdate it. It exists as an objective record that this exact content was registered at this exact moment by this exact person.
What's more, the system then allows you to:
prove your ownership later by checking the original text or file you registered with the system
allow you to check against AI output to see if there are enough similarities that your work has been used for training
Versioning — because work evolves
Creative work doesn't stand still. You...
