AI copyright infringement Start with proof of what you published.

If AI tools use your work, the first problem is proof. Encypher signs each piece as you publish, with your terms inside it. Later, a copy that keeps the mark can be checked against that dated record.

A record for your counsel, not legal advice or a verdict.

Content marked with rights terms, then a formal notice, then a crawler using the content after notice. Past a dashed line, a small gray gavel labelled For counsel and courts shows that outcomes are for courts, not the mark.
Marked work, a formal notice, then use after notice. What follows is for counsel and courts.
Dated
Each piece is signed when you publish it.
Terms inside
Your terms travel in copies that keep the mark. Stripped or rewritten copies may carry none.
Per sentence
Copied sentences can be traced to the article they came from.
Free for publishers
Signing is free, and you keep all of your licensing revenue.

Why an AI detector does not help

Provenance reads back a signed record: signed by Town Daily, made with AI: no, unchanged since signing. Detection runs unsigned text through an AI detector and returns a guess, such as 72 percent likely AI.
Provenance is a record anyone can check. Detection is a guess with a score.

An AI detectorAI detector: A model that guesses whether content was made by AI and returns a probability, not proof. guesses whether text looks machine-made. Your question is different: is this your work? Only provenanceContent provenance: The record of where a piece of content came from and how it changed, carried with the content itself., a record made when you published, can answer that.

AI detectors vs proof

What the record lets you show

A file holds a signed label in four layers: who signed it, what they declared including AI use, a fingerprint of the content, and a signature that seals them together.
The label sits inside the file. It names the signer, carries what they declared, fingerprints the content, and is sealed by a signature.
What and when
The exact text you published, and the date you signed it.
Your terms
The rights terms you signed with the work.
A match
Whether a copy matches your text word for word.
