Products and tools for preserving what matters
We preserve your voice, images, and text across three independent layers — physical, national, and private. If any one layer is lost, the others continue to protect your records, achieving permanence without dependence on servers or apps.
Designed to endure a 1,000-year timeframe, the system incorporates 20-year renewal cycles inspired by the Shikinen Sengu tradition of Ise Grand Shrine.
Physical Layer
Quartz glass engraving (300+ million year durability), UV laminate film protection (10-year outdoor durability). Distributed storage on Sado Island and Maui.
National Layer
Legal deposit under the National Diet Library Law. Voice converted to QR codes and deposited as PDF newsletters on a periodic basis.
Private Layer
GitHub Pages decoder (just 3 MB). Data lives inside QR URLs on paper. O(1) storage independent of record count.
A free, open-source tool that encodes voice, images, and text into a single QR code. Codec2 WASM at 450 bps fits up to 30 seconds of voice into QR Code Version 40 (2,953 bytes).
Runs entirely in your browser — nothing is sent to a server. Works offline.
Bulk mode splits data across multiple QR codes, enabling high-quality audio (Opus) with no time limit, images with no resolution limit, and unlimited text. Prepaid credits require no account, no personal information, and have no expiry.
