Chroniq turns every file you upload into cryptographic evidence — SHA-256 fingerprinted, UTC-timestamped, and sealed into a verifiable Proof Certificate that anyone can independently confirm without ever seeing your source file.
Drag and drop into your private vault. Files are encrypted at rest and never accessible to anyone but you.
Chroniq computes a SHA-256 hash from the raw bytes server-side and locks in a UTC timestamp — independent of any AI output.
Download a signed Proof Certificate PDF with a QR code. Anyone can verify authorship and hash without seeing your file.
Every capability of Chroniq is exposed as a REST API. Issue certificates and verify authenticity from your patent tool, LMS, CMS, document platform, or research pipeline — with API keys, versioned endpoints, and full OpenAPI docs.
# Verify a certificate — no auth required curl https://api.chroniq.io/api/v1/verify/CHR-A3F1E9C2-B4D7 # Upload a file & seal proof (server-to-server) curl -X POST \ -H "X-API-Key: pv_live_xxx" \ -F "file=@paper.pdf" \ https://api.chroniq.io/api/v1/projects/PROJ_ID/upload
Chroniq establishes evidence of possession and timestamped provenance. It does not automatically grant a patent, copyright registration, or a legal determination of ownership. Your certificate is a tool for building your evidentiary record.
