Digital evidence, before the dispute
Timestamped digital proof.
What is true stays true.
Photo, video, audio or document: create timestamped, geolocated proof anchored on a blockchain in 30 seconds, with integrity anyone can verify. To prove a job, a service, a property condition or a creation, with no technical background.
Inventory of exhibits
Prove that content existed, on that date, unaltered.
Everything Proov-It turns into dated, located evidence whose integrity can be checked. Every exhibit gets its certificate, verifiable by anyone.
In-app capture
In-app capture, the strongest proof
Unlike an uploaded file, an in-app capture is born inside the application. No more images retrieved or generated elsewhere and then submitted as evidence. Photo or video, including what is displayed on another screen.
StrongestFreeze a web page at a given moment
Capture the state of a page, a listing or a review before it is edited or deleted.
CertifiedCertify a photo
Prove that a photo is the one taken at that moment, and that it has not been edited since.
CertifiedCertify a video
A dated and geolocated video in which any later change can be detected.
CertifiedCertify an audio recording
An authentic, timestamped sound recording, unaltered since it was captured.
CertifiedA PDF certificate anyone can verify
Every submission generates a certificate that any third party can verify, without going through Proov-It.
VerifiableWho it is for
Built for anyone whose evidence may be challenged.
A date, a place, the condition of a property or the integrity of a file: as soon as it can be disputed, Proov-It freezes it.
Construction photo evidence
Electricians, plumbers, builders, drywallers, tilers, roofers: timestamped site photos, from the quote to the handover.
→02Proof of work completed
Call-outs, maintenance, repairs: before-and-after photos and time of visit, dated and geolocated.
→03Architects: site documentation
Site visits, minutes, snags, handover: a timestamped, geolocated project timeline.
→04Court experts and loss adjusters
Timestamped, geolocated, anchored inspection photos, with integrity the parties can check themselves.
→05Digital evidence for lawyers

→06Service delivery proof and condition reports
Deliveries, move-in, move-out, cleaning, damage: dated and geolocated photos and videos.
→07Online proof for individuals
Neighbours, rentals, purchases, creations: prove the prior existence and integrity of any content.
→A proof, then what?
It doesn't sit in a drawer.
Every submission becomes a usable, shareable document you can produce in a dispute.
- 01Send it for signature or validation by a third party.
- 02File it by folders, categories and tags.
- 03Produce it in a dispute, or to prove your good faith.
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.

Guides
Understanding digital evidence, case by case.
Timestamped photo evidence
eIDAS Article 41, national rules of evidence, the court's assessment: what gives a photo weight as evidence, and how a timestamp makes it stronger.
Timestamp comparison
Non-qualified timestamp, qualified timestamp, report by a public officer: evidential weight, cost and use of each tool, to choose for each case.
Handover and snagging photos
At handover, photograph the work, each snag and its clearance with timestamped, geolocated photos that every party can verify. First proof free.
Rental condition report
Move-in and move-out condition report: photograph every room with verifiable date, place and integrity, alongside the signed inventory. First proof free.
Insurance claim photos
Water damage, fire, storm: photograph the damage before repairs with timestamped, geolocated photos that the insurer and the loss adjuster can verify.
Prove prior creation
Drawings, texts, logos, mock-ups, code: prove a creation existed on a given date with a blockchain-anchored timestamp, alongside official filings.
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.
