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.

- 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

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.
What the record lets you show

- 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.
- Which sentences
- Which sentences were copied. This sentence-levelSentence-level attribution: Checking that one sentence came from a specific signed source unchanged, even when it is quoted on its own. layer is patent-pending.
