The Short-Text Provenance Gap

New EU rules say AI content must be marked, so people can tell what is real and what is made by AI. For short text, the rules admit this is very hard to do. Encypher does it. Here is why that matters for your business.

The rules left a gap

The EU wrote a rulebook for marking AI content. It is honest about one thing: marking short text is really hard. The usual tools need a lot of words to work. So the rulebook leaves very short text out.

In its own words, AI content should be marked “with the exception of very short text.”

Why this matters for your business

Short text is everywhere: headlines, quotes, captions, product copy, and AI answers. If you cannot mark it, you cannot prove it is yours. You cannot easily show what was made by AI. And the new rules still expect you to try.

What Encypher does

Encypher marks your text so it can be checked later, even when the text is short. The mark is invisible. It does not change how your words look or read. It stays with your words when they are copied and pasted. Anyone can check it, for free.

  • Prove what you published.
  • Show clearly what is AI and what is not.
  • Help meet the new EU rules.
  • Works on short text, where other tools give up.

Encypher’s approach is patent pending.

Being straight with you

It is not magic. If someone rewrites your text from scratch, the mark can be lost. It works best when your words stay your words. For stronger proof, Encypher adds more than one kind of mark, so your content stays protected across more places.

What this means for the new rules

The EU rules take effect on 2 August 2026. They ask you to mark AI content. Encypher helps you do that, even for short text. It does not make you compliant on its own: that depends on your full setup and the final rules. But it closes the exact gap the rulebook says is hard.
