How should the copy behave?

Invisible (best for emailing to readers) Looks and works exactly like your original: same pages, same selectable text, same file size. The reader notices nothing. Adds a hidden "no AI training" notice and a hidden mark that lets you trace a leaked copy back to who you sent it to. It does not stop software from reading the text. Locked Turns every page into a picture so the text cannot be copied or scraped, and fills the hidden text layer with decoy text. Readers can no longer search or select text, and the file is bigger.

Your details

Writer name for the copyright notice Personal copies (optional): one name per line

Stop software from reading the text (recommended) Crawlers and dataset builders that pull text out of PDFs get nonsense words instead of your script. The pages look identical, but Find, copy and paste and read-aloud stop working on this copy. It does not stop tools that look at pictures of the page (OCR or AI vision). Add the "no AI training" notice to the file's propertiesHidden metadata that well-behaved crawlers and tools read. Only visible in a PDF viewer's document properties.

WHAT EACH MODE DOES

Invisible: the pages look exactly like your original. Every font's text table is replaced so that software extracting the text gets unrelated words, not your script. Each page is also shifted by a few hundredths of a point, far smaller than a printer dot, in a pattern unique to that copy, and a rights notice goes into the file's metadata. Find, copy and paste and read-aloud do not work on a copy with text reading blocked; untick that option if the reader needs them.
Locked: pages become pictures, the text layer is replaced with decoy text, a faint pattern goes on the page image, and the same notice goes into the metadata. Optional name footer and watermark.
Personal copies work in both modes. Each person gets their own copy with its own ID, and you get a log of who got which.

Neither mode makes copying impossible: anyone who can see a page can photograph it. Keep your original file. Shielded copies are for sending.

QUESTIONS

Does it stop AI training on my script?

It stops the cheap, automatic route: software that pulls text out of PDFs. It does not stop tools that read pictures of pages, such as OCR or AI vision models.

Will my readers notice?

They won’t see a difference on the page. They won’t be able to search or copy the text, so if a reader needs that, send them an unprotected copy.

What about plagiarism?

This doesn’t prevent plagiarism. Personal copies make it possible to trace a leaked file, but please still copyright your work, use written agreements, and send copies only to people you trust.

Is my unprotected script stored on your system?

It never reaches our system in the first place, and that is deliberate. Script Shield runs entirely inside your browser: your script is opened, protected and saved on your own computer, and no copy is sent to us or to anyone else. Nothing is uploaded, so there is nothing on our servers to be breached, demanded in a legal request, or left behind by mistake. You can check this yourself: open your browser’s developer tools, watch the Network tab, and protect a script. Nothing goes out.

TRACE A LEAKED COPY

Found your script somewhere it should not be? Give this page your original PDF, the leaked file and your copies log, and it tells you which copy the leak came from. It works for Invisible copies, including files that have been re-saved or re-exported, as long as the text is still real text. It cannot read a leak that has been turned into pictures or retyped.
