Document Product Designs and Specs with Verifiable Proof
Help product developers record specs, CAD packages, and go-to-market assets as timestamped digital evidence for collaboration and IP documentation.
Physical and hybrid product development almost always involves sharing confidential specs with people outside your immediate team before any formal IP protection is in place: a manufacturer evaluating a CAD package, a potential licensing partner reviewing a spec sheet, an investor looking at a roadmap during due diligence. Provisional patents and NDAs help, but they take time to put in place and don't always cover the exact moment a design left your hands. ProofIt lets product teams create an independently verifiable, privacy-preserving record of exactly what a design, spec, or BOM looked like at the moment it was shared—so there's a fallback evidentiary trail even when the formal paperwork lags behind the actual conversation.
Common use cases
- Certify CAD files, BOM packages, and product specs before manufacturing or supplier talks
- Document roadmap or prototype packages shared with partners, investors, or licensing prospects
- Build an evidence trail for designs without publishing confidential files on-chain or anywhere public
- Timestamp a spec revision before and after a major design change, to establish a clear before/after record
What the evidence includes
- Hash-only external timestamping and chain registration—confidential specs are never disclosed
- Certificate retention and permanent blockchain records that survive subscription cancellation
- A privacy-first architecture built for sharing confidential product materials under NDA
How it works for product developers, inventors, and hardware/software product teams
- Finalize the specific spec, CAD package, or BOM revision you're about to share externally
- Certify it in ProofIt to generate a hash, timestamp, and certificate for that exact revision
- Share the package with manufacturers, partners, or investors under NDA as needed
- Keep the certificate on file as part of your broader IP documentation, alongside any provisional patent filings or licensing agreements
Frequently asked questions
Does certifying a CAD file expose confidential product details?
No—only the file's SHA-256 hash is sent for timestamping and, optionally, blockchain anchoring. The design itself is never published on-chain or disclosed to the timestamping authority.
Does this replace a provisional patent filing?
No. A ProofIt certificate is independent evidence of existence, time, and integrity—it's a complement to, not a substitute for, formal IP protection like a provisional patent where that's the right tool for your situation.
What happens to my certified specs if I cancel my subscription?
See what happens to a timestamp when a subscription ends for the full retention policy—in short, hashes and blockchain records are permanent, certificates remain accessible for a year, and original files are deleted 30 days after cancellation unless you download them first.

Important limits
ProofIt creates timestamped, independently verifiable evidence of existence, time, and integrity. That is not the same as automatic legal ownership, a copyright guarantee, or guaranteed court acceptance. Platforms and authorities decide outcomes when you include a certificate with a complaint.
