Your PDF reads normally to people. Copy, paste and AI extraction get decoy text.
Copy, paste and extraction return decoy text.
Text reads normally on screen and in print. Copy, paste and automated extraction return decoy text, so the real content does not reach an AI tool by the usual route.
A password to open, and limits on copying, printing and editing.
AES-256 open password and permission restrictions, all on by default and each one optional. TDMRep and XMP metadata state that text and data mining is reserved.
Hidden data that travels with the file gets stripped.
Metadata, bookmarks, comments, links, forms, attachments and JavaScript can each be removed on their own. The title stays.
Blur or black out the passages you mark.
Mark the passages that matter and hide them with blur or blackout. The hidden text is removed from the file, so it cannot be read or copied by anyone, not even by AI reading a screenshot. Everything else on the page stays untouched.
A visible watermark and an AI notice on every page.
The watermark and the notice state the document's terms where every reader sees them.
Every recipient gets a unique copy. A leak points back to its source.
Each recipient gets a personal copy with a visible reference line, a hidden CopyID and its own decoy mapping. A leaked file is traced to its source by hash, CopyID, reference line or decoy fragments, and every run produces an audit receipt.
Drop in a PDF. Layout, fonts and sizes stay as they are.
Pick what to lock, clean, redact and watermark, and who gets a copy.
Get your file, or a ZIP of personal copies with an audit receipt.
Add LockAI to Outlook, Word and PowerPoint, on Mac and Windows, or right-click any file in Windows. Same protection, one click from where you already work.
In Outlook, one button locks every PDF attached to the email before you send it. In Word and PowerPoint, one button exports the file to a locked PDF. In File Explorer, right-click a PDF, Word or PowerPoint file and choose LockAI this file: the locked copy lands next to the original. IT teams install the add-ins once from the Microsoft 365 admin center and everyone gets them.
Contracts, financial figures and client information that should stay in a controlled environment, with a traceable copy for every recipient.
Without LockAI: A full contract gets pasted into an AI tool for a quick summary, and nobody knows it left.
Client files and patient records, where a leak is both a confidentiality breach and a regulatory exposure.
Without LockAI: Patient data gets copied so an outside AI can weigh in, with no proof that preventive steps were in place.
Course material and assessments, protected against being copied wholesale into an AI tool for an instant answer.
Without LockAI: An exam gets pasted into a chatbot the night before, and the answers circulate.
Unpublished manuscripts shared with editors or agents, kept out of AI tools and traceable if a copy surfaces.
Without LockAI: A manuscript gets pasted into an AI tool for feedback before it is ever released.

Talk to usThe everyday route text takes into an AI tool: copy, paste and automated text extraction. All of them return decoy text instead of the real content.
No. Layout, fonts and sizes stay as they are. It reads and prints the same for people.
Yes, and an AI that reads the picture sees what a person sees. That is why Pro lets you mark the parts nobody should read at all: they are blurred or blacked out and removed from the file, so a screenshot shows nothing there either.
No. The decoy layer is a barrier that makes extraction a deliberate act. If you need the file to stay closed, add the AES-256 password.
Turn on a copy per recipient. Each copy carries its own ID and decoy mapping, so a leaked file or pasted fragment points back to one person. The audit receipt records every run.
Yes. The Outlook add-in locks the PDFs attached to an email, and the Word and PowerPoint add-ins export your file to a locked PDF. In Windows, right-click any PDF, Word or PowerPoint file and choose LockAI this file.
Yes, on Enterprise. An admin turns each feature off, optional or required for the whole organization, and the server holds to it in the web app, Outlook, Word, PowerPoint, the Windows right-click and the API. Presets and rules pick the settings for each file, like Confidential for any email that leaves your domain.
Nothing of their content. Your file is deleted once you download the result, or after a short window if you don't. On Enterprise, the activity log keeps each file's name, page count and fingerprint, so you can see who locked what and when.
