01The problem

Your work gets absorbed. Copied. Fed to models without credit. You made it — you should be able to prove it existed before they took it.

02How it works

Paste your work. Get a witness. Keep everything else.

01

You submit

Paste your text — paragraphs, articles, songs, poems & even AI chats. Stenographer 10000 has launched and handles up to 10000 characters. Nothing fancy to learn.

02

We hash and timestamp

A cryptographic fingerprint of your exact content, sealed against a certified third-party time server. The content stays yours — and now, so does the proof.

03

You get a receipt

A formal record — downloadable & emailed. Verifiable by timestamped hash. *Coming Soon - Paid tiers featuring paper proof mailed with tracked postmark.

04

It verifies itself — forever

The receipt carries everything needed to check it. No blockchain needed. No login. No dependence on us. If EigenWitness vanished tomorrow, your proof would still stand.

03The whole promise

A witness testifies to what it saw. Nothing more, nothing less.

We witness that your content was submitted, on a date, in a form. We don't claim who made it first, who owns it, or whether it's original — and that honesty is exactly what makes the record trustworthy.

What we do

  • ✓Fingerprint your exact content
  • ✓Timestamp it, third-party certified
  • ✓Issue a receipt you can verify anywhere
  • ✓Cooperate with lawful legal process

What we never do

  • ✗Own your work
  • ✗Train AI models on it
  • ✗Sell or share it
  • ✗Pretend to be your lawyer
04Why it's different

Not another certificate.
A record that stands – on its own.

No blockchain required
No ledger to depend on, no chain to keep alive. Plain, durable cryptography — the approach the major standards bodies moved toward, without the baggage.
Verifies offline
The record is self-contained. Check it on your own machine, in three years, with nothing from us. Other systems' proofs get stripped in transit — yours doesn't.
*Coming Soon - More than a hash
Optionally, a semantic fingerprint of what your work contains — far harder to fake retroactively than a timestamp alone. This part no one else has, and we will soon.
*Coming Soon - A paper trail, literally
A tracked, postmarked envelope for paid tiers. Courts have honored postmarks for a century — old-fashioned, and quietly powerful.
05What it costs

The witness is free. The intelligence is the upgrade.

Witnessing your work shouldn't cost anything — it's a right, not a feature. We earn our keep on the deeper analysis, for those who want it.
