DEEPSTAMP

Prove your work is yours, even after an AI rewrites it.

DeepStamp tells creators when their work has been copied, paraphrased, or used to train an AI model without permission.

THE PROBLEM

A rewrite is all it takes to erase the evidence.

Tools that only read wording

Plagiarism checkers compare exact wording. A paraphrase, or a single pass through an AI, is enough to break the match.

Courts have already moved

Courts are starting to order AI companies to pay for the content they used, but creators still have no way to know where their work ends up.

No evidence, no compensation

Every path to compensation starts with evidence creators can't produce today.

A rewrite is all it takes to erase the evidence.

WHY DEEPSTAMP

It reads the facts, not the words.

DeepStamp identifies a work by the facts it asserts, not its wording, so the match survives even a complete AI rewrite. And because every registered work is timestamped, DeepStamp can prove which version came first: the evidence licensing deals and courts actually require.

Your article, registered first

Hyundai's new Tucson PHEV delivers 288PS, up from 252PS in the previous model year.

AI rewrite, still detected

The latest plug-in hybrid Tucson now produces 288 horsepower, a clear jump from last year's 252.

Different words, same facts. Match confirmed.

Register

Submit your work. DeepStamp extracts the facts it asserts and timestamps them.

Detect

Run a suspected article or AI output through DeepStamp, and it checks the facts against your original, instantly.

Report

The detection becomes a downloadable evidence report, ready to use in licensing negotiations or legal action.

SUPPORTED CONTENT

Whatever form your work takes.

Text

Articles, manuscripts, scripts. Identified by the facts they assert, so the match survives an AI rewrite.

Images

Photos, illustrations, designs. Register them, then check for unauthorized reuse.

Audio

Music, podcasts, recordings. Register them, then check for sampling, covers, and other reuse.

THE DETECTION REPORT

You get evidence, not just a result.

A detection doesn't just show up on screen. It's issued as a downloadable report.

Timestamp proof of when it was registered

Side-by-side comparison of the original and the detected content

Tamper-evident proof elements

A format ready for licensing negotiations and legal action

PROVEN IN PRODUCTION

Already running in production, not a lab demo.

In the same pilot, DeepStamp separated true derivatives from unrelated text more accurately than general-purpose AI similarity models. Factagora is also named a Key Startup in Gartner's coverage of AI disinformation security.
