Individuals, creators, freelancers
Online proof, whenever you need it.
A dispute with a neighbour, a landlord, a seller? A creation to protect? An agreement to keep? Create timestamped, geolocated online proof anchored on a blockchain in thirty seconds, from your phone. First proof free.
We have all had that moment of thinking “I should have taken a photo”. The trouble is that a photo on a phone proves very little: its date can be changed, it can be edited, and nothing shows it has stayed the same. Online proof with Proov-It is the same photo, but dated, located and frozen for good.
You take the photo, video or recording directly in the app, or you upload a document. Proov-It timestamps it, geolocates it and anchors it on a public blockchain. You receive a PDF certificate that anyone can verify: your neighbour, your landlord, your insurer, a judge.
No subscription for individuals: one token equals one submission, and the first is free. Up to 20 files of 100 MB in a single submission, so the full condition of a home or a 90-minute video fits in one proof.
Use cases
Online proof: what an individual certifies.
Rental check-in and check-out
Entry and exit, room by room, to get your deposit back without argument.
Neighbour disputes
Nuisance, damage, encroachment: dated evidence of what is happening, and since when.
Buying and selling between individuals
The condition of the item, the listing, the agreement reached, frozen on the date of the transaction.
Water damage and other losses
Water damage, a scrape, a theft: record it immediately, before the assessor.
Agreement or acknowledgement
A document signed between you, submitted and dated, that either of you can verify.
Why Proov-It
Why it beats a photo on your phone.
The date and place are recorded
The timestamp and geolocation are recorded at capture, then the fingerprint is anchored on a blockchain. That record can no longer be changed, not even by us.
The file can no longer be edited
Every file gets a unique fingerprint. The slightest change breaks it, and that can be checked publicly.
Simple and cheap
Thirty seconds, no skills, one token per submission, the first one free. Nothing like the cost of a formal report.
How it works
A proof in three steps.
No jargon, no technical skills. You submit or you capture, we certify.
Choose or capture
Documents, photos, videos. Or take a photo or video directly in the app.
Add the context
A comment, tags, a folder. To organise your proofs and find them easily.
Submit
You receive a PDF certificate attesting to the file's existence and integrity on the anchoring date and, for a capture made in the app, the geolocation recorded at that moment.
Does it hold up in court?
In France, where Proov-It is based, evidence may be brought by any means unless the law requires a specific form of proof (Article 1358 of the French Civil Code). The EU eIDAS Regulation, which applies in every Member State, adds a non-discrimination principle: an electronic timestamp cannot be denied legal effect solely because it is not qualified (Article 41). In 2025, the Marseille judicial court (20 March 2025, RG 23/00046) relied on blockchain timestamps, recorded by a bailiff and supported by other evidence, to establish the prior existence of creations. It is a first-instance decision: it does not make a blockchain anchor sufficient evidence on its own.
A Proov-It certificate can be produced as evidence; the court assesses its weight. We attest to the anchoring date, the integrity of the file and, for a capture made in the app, the recorded geolocation, not the truth of its content.
Frequently asked questions
What we are often asked.
Does online proof count before a judge?
In France, evidence may in principle be brought by any means. A Proov-It certificate can be produced as evidence, and the court assesses its weight. In 2025, a French court relied on blockchain timestamps, among other evidence, to establish the prior existence of creations.
Do I need to understand blockchain to create proof?
No. You take the photo, add a note, submit. The blockchain works behind the scenes.
How much does online proof cost for an individual?
One token per submission, no subscription, with volume discounts by pack. The first submission is free when you sign up, no credit card needed.
Can other people see my photos?
No. Your files stay private, hosted in France and encrypted server-side. Only a fingerprint, which reveals nothing about the content, is written to the blockchain.
