Provenance · attributed writing

Prove who wrote it.
Every sentence.

Everyone's asking whether a machine wrote this. Provenance gives a checkable answer: each span of text is marked as written by a person or by an agent, and signed, so anyone can verify it.

Writing that shows its work

Write as you normally would and let an agent help where you want. Provenance records who wrote each span, and that record goes with the document wherever it's shared.

No guessing, no "AI detector" scores. It records who wrote each part at the moment it's written.

Newsrooms

Publish with a signed authorship record. Readers can check it themselves.

Disclosure rules

Where AI use has to be disclosed, Provenance is the disclosure, with a signature behind it.

Code

See which lines a person wrote and which an agent wrote, for contribution policies, licensing and reviews.

How verifying works

  1. Every span is tagged with its author as it's written, a person or a named agent.
  2. The record is signed with a certificate from Signet, sprwl's own certificate system.
  3. Anyone with the document can check the signature. They don't need a sprwl account.
  4. Any edit after signing shows up. Nothing changes quietly.

Note for Armitage: I've described this from the homepage line "who wrote what, span by span, verifiable." Please check the details (especially whether outsiders can verify without an account) against how Provenance actually works.

One sentence: "Proof of who wrote what, line by line." It's the way in. Once a team trusts it, the rest of the OS follows.
