Prove it now. Avoid costs later.
Whether it's a property condition, a quote, an acknowledgment of debt, or work in progress
Codex creates a timestamped, independent and verifiable proof in seconds. From €29.
What would you like to secure?
A photo or a document. Codex creates a timestamped, independent and verifiable proof.
A simple and fast proof. Before it becomes expensive.
Your independent, verifiable proof from €29.
Codex records a timestamped proof of your documents and photos in an independent and public registry. No files stored. No modification possible.
Open a professional accountCodex certifies that a document, an agreement or a decision existed at a specific point in time — without ever storing the file. You keep your document. Codex keeps the proof.
This proof is recorded in an independent registry, timestamped and publicly verifiable for free. Codex acts as a neutral technical trust layer — with no access to content, no artificial intelligence, and no interpretation.
How does it work?
Codex generates a unique fingerprint of your file or photos, timestamps it, and records it in an independent registry. This fingerprint cannot be modified once recorded. Your document is never transmitted or stored.
Why is it reliable?
A Codex proof does not rely on a declaration — it is based on a neutral technical record that can be publicly verified. Your document is neither read nor stored, only its digital fingerprint is recorded.
Who is it for?
- Individuals: property condition, Airbnb stays, neighbor disputes, shipments
- Freelancers and trades: quote sent, work started, signed contract
- Professionals: sales agreements, internal decisions, acknowledgments of debt
- Organizations and associations: reports, resolutions, agreements
In practice
- Take your photos or upload your document
- Codex generates a unique fingerprint and timestamps it
- You receive a verifiable proof certificate
- The proof can be checked publicly at any time, free of charge
What is Codex for?
Codex does not replace a notary, a bailiff or a lawyer.
It is a simple tool that comes in at an early stage,
helping to establish clear facts before a situation becomes complex or costly.
In just a few seconds, you create an independent technical proof. In many cases, this is enough to clarify a situation and prevent a disagreement from escalating.
Codex acts as a neutral technical trust layer: you demonstrate that a document or a situation existed at a specific point in time, in a given version, without ever revealing its content.
Why use Codex?
In a professional context, one question frequently arises: how can you demonstrate that a document existed at a given date, and that it corresponds exactly to the version produced?
Emails, screenshots, internal transmissions or local archives can be discussed or challenged. They often rely on internal systems, modifiable metadata or non-independent technical environments.
Codex provides independent technical proof, publicly verifiable and neutral. It does not rely on a statement, but on the registration of a unique digital fingerprint recorded in a publicly accessible registry.
This approach transforms a claim into a technical fact. It does not replace legal mechanisms, but it stabilizes exchanges by providing an objective and verifiable point of reference.
Concrete use cases
A signed contract
Simply take a photo of the document.
You record its existence at a specific moment,
without formalities or travel.
Useful to keep a clear trace from the start.
A quote sent
A screenshot or a photo is enough.
You keep a simple proof of what was shared,
avoiding discussions about “what was said or not”.
A condition or situation
Before a job, a delivery or an exchange:
a few photos allow you to capture reality as it is.
This is often where everything matters.
A decision or an exchange
A document, a note, an informal agreement:
you can keep a trace without exposing its content,
while setting a clear point of reference.
Codex is not a legal procedure.
It’s a simple way to establish facts,
often with a photo, before a situation becomes complicated.
A practical first step to clarify things,
reduce tension… and sometimes avoid going further altogether.
How it works (technical overview)
- You keep your document or photos.
- A unique digital fingerprint is generated.
- This fingerprint is timestamped and recorded in an independent registry.
- The proof becomes publicly verifiable.
No files are stored.
No content is analyzed.
Codex does not rely on artificial intelligence.
Its process is deterministic and reproducible.
Independent verification
Anyone with the original file can recompute its fingerprint and compare it with the one recorded in the registry. If they match, the integrity of the document is confirmed.
Difference from traditional cloud storage
Unlike a storage service, Codex-Log does not retain any document. Only the cryptographic digital fingerprint is recorded. The content remains exclusively under the control of its owner.
What distinguishes Codex
- No document storage
- Independent and publicly verifiable proof
- Pay-per-use model (no subscription)
- B2B compatible (bank transfer available)
- Automatic invoice generation
- No AI — no artificial intelligence involved
A simple proof. Lasting peace of mind.
Codex does not replace trust. It secures it.
You no longer rely on a statement, but on independent proof, publicly accessible and timestamped.
