01
The Problem Worth Naming

Authorship has become illegible.

Readers can no longer tell how a piece was written — and many have stopped trusting that it matters. That's a problem for writers who take the work seriously. Ink & Proof exists because craft deserves to be legible again.

02
What Ink & Proof Actually Does

A verified record of how your writing was made.

Write in our distraction-free editor. When you're done, generate a Proof — a cryptographically signed credential that captures your sessions, your revision history, and your honest disclosure of any AI involvement. Four tiers, no binary judgment.

03
Honest by Design

We don't claim to be foolproof. We claim to be transparent.

A determined bad actor can retype AI output by hand and pass our behavioral checks. We say so publicly. What the system does defeat is laziness — and what it builds is something more durable than detection: a public commitment, backed by methodology you can read and verify yourself.

Questions
Can't someone just retype AI output and pass your checks?
Yes. If a writer is patient enough to manually retype AI-generated text across multiple sessions with realistic edit density, our behavioral signals won't catch it. We say this openly. What the system defeats is laziness and carelessness — the vast majority of AI misuse. It doesn't defeat deliberate, patient deception. No credentialing system does.
Why do I have to write in your editor? I already have a workflow.
Because behavioral signals — session count, revision history, edit density — only exist if we can observe them. An upload of a finished document tells us nothing about how it was made. The editor is the methodology, not a feature.
What's the point of the “Human-Directed” tier? Isn't that just admitting you used AI?
That's exactly what it is — and that's the point. Readers deserve to know. Writers who collaborate meaningfully with AI and take full editorial responsibility for the result are doing something legitimate. Refusing to credential that work would just push it underground.
Who actually checks these stamps? Do readers care?
Honest answer: not yet, at scale. Right now the stamp signals something to the readers who are already paying attention to AI provenance — and that audience is growing. The value compounds over time and with adoption.
How do I know Ink & Proof won't change the methodology and retroactively change what my old Proofs mean?
Every Proof records the methodology version it was certified under. Old Proofs link to the methodology that applied when they were generated. We commit to versioning publicly and never rewriting history.
Is my writing stored on your servers? Who owns it?
You do, entirely. We store drafts and session metadata to generate the Proof. We don't train on your writing, sell it, or share it. The receipt page publishes only what you explicitly disclose.
$8/month for a badge — is that worth it?
The free tier covers three Proofs a month, which is enough for most writers. Pro is for writers publishing regularly who want an author archive page and unlimited Proofs. Whether it's worth it depends on how much you value the signal — we're not going to oversell that.
