Prove you created it. Cryptographically. Every piece of content gets a tamper-proof record of authorship anchored to an immutable transparency log.
Four steps from upload to verified proof.
Drag and drop any file — photos, documents, music, code, or video. Your file never leaves your device; only the SHA-256 hash is computed.
Our AI automatically classifies your content, extracts metadata, and suggests tags. For images, EXIF data is captured. For code, language and framework are detected.
Your content hash is signed with your personal Ed25519 key and anchored to the Truthlocks transparency log — creating an independently verifiable proof of authorship.
Get a shareable proof page, embeddable verification badge, and downloadable certificate. Anyone can verify your authorship without needing Truthlocks.
Protect every shot before publishing. Establish a timestamped record that proves you were behind the lens — useful for licensing disputes, portfolio verification, and copyright claims.
Register original artwork, illustrations, and designs. The cryptographic proof is admissible evidence of prior creation and independent of any platform.
Protect tracks, stems, and compositions before sharing with collaborators or labels. Establish first-to-file proof of your musical work.
Protect articles, manuscripts, research papers, and scripts. Prove you wrote it before it was published, shared, or leaked.
Protect raw footage, edits, and final cuts. Establish provenance for your video content across platforms.
Timestamp research data, lab notebooks, and pre-prints. Create an immutable record of discovery priority.
Your file never leaves your device. Only the SHA-256 hash is transmitted and recorded.
Each user gets a personal Ed25519 signing key. Attestations are cryptographically bound to your identity.
Proofs are anchored to an append-only log (RFC 6962). Tampering is cryptographically detectable.
