Sign what you publish. Mark what your AI creates.

  1. Copies of a news story, photos, and chat answers spread across the screen, and the Town Daily name tags slide off them.

    Your work travels. Your name doesn't.

    Articles, photos, and video are copied and reposted every day, and the creator's name rarely goes with them.

  2. A brown thumbs-up equals two characters: a yellow thumbs-up marked hand, plus a brown tile marked +3 for the skin tone.

    Text carries more than meets the eye.

    A thumbs-up emoji looks like one symbol. Underneath, it is two characters: one for the hand and one for the skin tone.

  3. A needle sews a gold thread under the sentence The pool opens Monday, and the stitches fade from sight.

    We put a signed label inside the text.

    Encypher writes it into characters that never show on screen. Readers see the same words; software can read the label.

  4. A gold thread runs from a photo to a video and sews a gold border around each one.

    Files carry one too.

    Photos, video, audio, and documents hold the label inside the file, using the open C2PAC2PA: The Coalition for Content Provenance and Authenticity: the group that publishes the open standard for content labels. standard.

  5. A gold tag on the thread reads Made by: Town Daily and Made with AI: No, with the blue Encypher badge on it.

  6. The sentence now says The pool opens Friday. The blue badge has cracked in two and turned gray, and a navy tag reads Changed.

    Change one word, and the seal breaks.

    Any edit made after signing shows up when the work is checked.

Anyone can print a label. Only a trusted one counts.

A letter sealed with anyone's stamp tells you nothing. A letter sealed by someone the checkers trust tells you who sealed it.

Two sealed letters. The letter with Encypher's blue badge, from a signer the checkers trust, passes the check. The letter with a gray look-alike badge, from an unknown signer, does not pass.

Good questions.

Does the label prove something is true?
No. It shows who signed it, what they said about it, and if it changed. It does not check facts.
What if someone copies the words?
The label comes along on most apps and sites. Some tools remove hidden codes, and pasting into Microsoft Word can break it. Then the checker says it found no label.
Do people need an account to check?
No. Anyone can check a label for free.
