Prior art at AI speed. Cryptographic proof. Court-admissible certificates from £10.
"The patent system was built for a world that moved slowly. Ideas today don't wait. Neither should your protection."
Proofr · proofr.ltd · Worldwide
No lawyers. No filing fees. No multi-year wait. Submit your idea, we hash it, timestamp it, and issue your certificate. Done.
Type a description, upload a document, attach a photo of notes on a napkin, send a voice memo. Any format. Our consultancy add-on helps you word it for maximum protective effect.
Your document is instantly converted into a unique SHA-256 fingerprint and anchored with an RFC 3161 trusted timestamp. Your idea is sealed to the exact second — tamper-proof, permanent, and verifiable by anyone.
Receive your unique PRF-2026-XXXXXXXX certificate immediately. Attach it to emails, pitches, proposals. This was mine, on this date, and the world can verify it. No ambiguity.
These are patterns that repeat across industries, company sizes, and continents — wherever ideas change hands without protection.
A founder timestamps their pitch deck 20 minutes before a VC meeting. Six months later, a competing startup emerges with a near-identical model backed by the same firm. The Proofr certificate shows the idea existed before any contact was made.
Two co-founders split. Both claim to have originated the core product concept. The one who timestamped their initial concept note wins the argument before it reaches a lawyer or courtroom.
A UX designer submits a detailed concept to a prospective client. The client launches a near-identical product with another agency three months later. The designer's Proofr certificate, issued before the brief was submitted, gives them the evidence they need.
A company timestamps their internal brief and working documents before engaging an external consultant. When the consultant later files a related patent, the company has prior art evidence predating the engagement.
A producer shares a track concept with a label A&R. The label passes. Two years later, a signed artist releases something strikingly similar. The producer's Proofr certificate, issued the day the concept was recorded, tells the real story.
A researcher timestamps their working paper while under peer review. When a rival lab publishes first, they demonstrate independent prior development — a distinction that matters enormously in academic priority disputes.

Accessible by design. Every innovator deserves fast, credible protection.
Your idea, sealed and verified. A permanent record of prior art you can carry into any room, any pitch, any dispute.
We help you frame your idea with protective language before we hash and seal it. Maximum legal effect.
Strengthen your certificate with supporting evidence — all timestamped and linked to your PRF record.
Every Proofr certificate rests on three globally-recognised technical pillars. Knowing what protects you builds the confidence to use it in any room.
Think of it as a fingerprint for your document. SHA-256 produces a unique 64-character string — your document's digital DNA. Change even a single comma and the hash becomes completely different. No one can alter your idea after the fact and claim it's the original.
Works on anything — a typed description, a PDF, a photo of a napkin, a voice note transcript. Your content stays private; only the fingerprint is sealed.
SHA-256 secures Bitcoin, protects online banking, and signs US Government software updates. The gold standard of document integrity.
An international standard governing tamper-proof records of when something existed. An independent Timestamp Authority receives your hash, signs it cryptographically, and returns a token proving: this hash existed at this exact moment. The TSA's signature cannot be forged or backdated.
Accepted as legal evidence in UK, EU, and USA courts under the Electronic Communications Act, eIDAS Regulation, and ESIGN Act.
Software publishers, law firms, and EU-regulated digital notaries. Billions of RFC 3161 timestamps issued daily. Proofr uses the same standard.
Your PRF reference — PRF-2026-XXXXXXXX — is your permanent, public, searchable record in the Proofr registry. It ties together your hash, timestamp token, and date of protection into a single verifiable identity.
Anyone can go to proofr.ltd/verify and enter this number to confirm: this certificate is genuine, issued on this date, and the document hash matches.
Include in pitch deck footers, covering emails, and beside the Proofr Kite Mark. Reference it in any NDA you sign. It leads directly to the full cryptographic record.
Every Proofr certificate carries a unique reference, cryptographic hash, verified timestamp, and the Proofr seal.
We are not an innovator's weapon against investors. We are a mutual truth standard. Anyone can protect their version of events.
You had the idea. You can prove it. Proofr gives you a cryptographic record that no NDA, no handshake, and no corporate legal team can overwrite. Walk into every room with confidence.
You heard a pitch. Your team built something similar, independently and legitimately. Proofr lets you protect your side of the story too — so no one can rewrite history against you either.
A VC firm can timestamp their internal evaluation memo. An employer can seal the date they briefed a team. Proofr is a level truth surface for everyone.
"Fred Smith outlined the FedEx hub-and-spoke model on a napkin at Yale. Howard Schultz sketched the Starbucks concept on a notepad in Milan. Every one of those moments was unprotected. The idea existed. The proof did not."
Today, that napkin can be photographed on your phone and uploaded to Proofr in sixty seconds. The image is hashed, timestamped, and sealed. The moment you had the idea — the coffee shop, the flight, the 3am spark — is now a permanent, verifiable record. Not a memory. Not an anecdote. Proof.
We are not here to replace the patent system — we are here to make prior art protection fast, affordable, and universal.
