For freelancers, photographers, and creators

Before sending
your work,
generate a proof.

Send your work with proof — not just trust.

Takes 30 seconds. No signup required.

Used by freelancers to protect work before delivery.

The three moments that matter
1.You finish your work. You're ready to send.
2.You generate a proof in 30 seconds. Timestamped. Legally valid.
3.You send your work with the proof. Your client knows you're protected.

The problem

Image theft is not a legal problem.
It is a proof problem.

When someone steals your image and publishes it, the question is not who made it. Everyone says they made it. The question is who can prove they had it first. Right now, can you?

01
They publish first
Someone finds your image, uploads it to a platform, mints it as an NFT, or posts it as their own. Now there is a public timestamp on their version. Not yours.
Happens every day
02
You argue. They argue.
You say you made it. They say the same. You have your files on your hard drive. They have a public transaction on the blockchain. Screenshots prove nothing. File dates prove nothing.
Your word vs theirs
03
Proof wins
A cryptographic timestamp from a qualified trust authority is the only thing that settles this. It proves you had the exact file at an exact moment in time. No one can fake that retroactively.
eIDAS / Tezos / SHA-256
How it works

Two minutes.
Permanent proof.

You do not need to understand cryptography. You need to drop your image and click one button.

Step 01
Generate proof first
Generate a proof immediately before sending your work. This creates a legally valid timestamp proving you had the file first. 0.08 EUR. Takes 30 seconds.
Step 02
Send with proof
Send your work to the client with the proof link. They can verify it independently — no SBIX account needed. Your ownership is now on record.
Step 03
Optional: scan for copies
Already published something? Drop it here. Free scan checks 6.4M indexed images to tell you if it's already circulating — and where.
Step 04
You are protected
If anyone disputes your ownership later, you have a permanent, independently verifiable answer. eIDAS qualified. Tezos anchored. No one can fake that retroactively.
Real scenarios

This is not hypothetical.
It happens to people like you.

NFT artists
Someone minted your artwork before you did.
You created the piece. You were about to mint it. But someone found it in your preview posts or portfolio and minted it first on Teia or Objkt. Now they have a blockchain timestamp and you do not. SBIX finds the match, shows you the date, and lets you build a counter-evidence package.
Scan
See if your work is already minted somewhere.
Certify now
Create proof dated before the dispute escalates.
Dispute
Send the verification URL to the platform. Let the timestamp speak.
Photographers
Your photo is being used without credit or payment.
Your shot is on a website, a campaign, or social media with no credit and no license fee. You need to prove you took it first. A file creation date on your hard drive is not enough. A certificate from a qualified trust authority is.
Scan
Find where your images appear across 6.4M indexed sources.
Certify
Timestamped proof at 0.08 EUR. Not 500 EUR in lawyer fees.
Evidence
PDF certificate + verification URL + blockchain anchor.
