Reasons to doubt this

AI cross-check (GPT)

Digify (digify.com) is a self-serve SaaS that provides per-recipient PDF watermarking/tracking and is marketed to teams (not only enterprise SDKs/contracts), contradicting the claim that incumbents only sell enterprise DRM with annual contracts.

AI cross-check = a peer model flags a logic issue. Editorial fact-check = a web-sourced correction. The card text is never rewritten; corrections sit beside it.

The pitch

Qwen

For PR teams sending embargoed press kits, turns a master document and recipient list into per-journalist spymarked copies and identifies the leaking recipient from a leaked PDF or text in under 5 minutes.

Who it's for

PR agencies and entertainment/game publicists sending embargoed press kits; today they cope with password-protected PDFs, visible watermarks, and manual per-journalist emails.

The problem

Legal: an embargo leak can breach client contracts; time: identifying which recipient leaked can take days of manual comparison.

How to build it

Web app: upload master PDF/DOCX plus recipient CSV, download a spymarked file per recipient, then upload/paste suspected leak to get an attribution report.

How it makes money

PR agencies pay $199 per campaign or $99/month because one embargo leak can cost a client; free passwords/visible watermarks do not identify which recipient leaked.

Why it doesn't exist yet

Incumbents sell enterprise DRM or forensic watermarking with SDKs and annual contracts, not campaign-scale self-serve; indie gap: lightweight per-campaign canary markers and a simple leak-scan report.

First users

First 10 users come from the HN 'Spymarks, not Watermarks' thread, boutique game/film publicists, and independent PR agencies offered a free scan of a past leak.

Build size

1-2 people x 10 weeks; includes PDF/DOCX text extraction, recipient manifest, invisible/micro-variant marker insertion, leak scan, signed report; excludes image/video watermarking, email delivery, DRM, legal takedown.

Biggest risk

If most embargo leaks are cropped screenshots or paraphrased text that strip or omit the markers, the product cannot produce attribution.

Conditions for a hit (all 3 required)

Upload a master PDF/DOCX and a CSV of up to 100 recipients; within 5 minutes it outputs one file per recipient, each containing a unique 12-character recipient code extractable from copied text or pdftotext and at least one visible footer reference.
Upload a leaked PDF or paste at least 200 words of leaked text; within 60 seconds it returns up to 3 recipient codes, the matched marker IDs, and a confidence score.
After a scan, it produces a signed JSON/PDF attribution packet containing SHA-256 hashes of the master file and recipient manifest plus matched excerpts, downloadable within 30 seconds.

AI self-confidence 50/100 — self-reported likelihood of meeting the criterion, not a business success rate

Exclusions ▾

A visible watermark generator or C2PA metadata signer must not count.
A generic canary token that only alerts when a link/file is opened, without leak-text attribution, must not count.
Image/video forensic watermarking must not count.
