puit.is
Proof of origin for the age of synthetic media.
Decentralised provenance combined with tamper-evident public anchoring. Preserving proof of origin, authorship, and continuity across formats and platforms. Built for cultural memory, institutional records, and digital media that must stay verifiable over time.

Proof. Protect. Preserve.
Every export, compression, or migration can sever a digital object from its origin. Puit.is adds a provenance layer designed to survive that journey.
Proving origin, protecting authorship, and preserving verifiable records without becoming a central authority.

Content. Context. Confidence.
Reliable verification needs more than a file or a claim. It needs context: who registered it, when, and whether the link survives transformation.
Puit.is is built for repeatable, inspectable checks that outlast any single platform.

Embed. Extract. Verify.
An imperceptible signal embedded at source, linked to a tamper-evident public record. Recoverable after compression, edits, or migration. Verifiable without relying on any single platform or gatekeeper.
Embed at source
Attach provenance before the file starts moving.
Extract later
Recover the signal after edits, compression, migration, or reposting.
Verify openly
Check the origin claim without relying on one central authority.
Built first where continuity matters most.
Archives, museums, rights holders, and public institutions are where digital origin first becomes non-negotiable.
The same need is spreading across media, licensing, and AI-generated content. Puit.is starts with high-consequence provenance and scales from there.
