Local first
Your working files stay on your device unless you explicitly run a backup.
Research tools, built with restraint
Safer workflows for knowledge that matters.
YuChe Lab builds small, auditable tools for researchers and knowledge workers. The emphasis is simple: keep people in control of their files, credentials, and recovery path.
Current project
Codex Cold Archive
A local-first workflow for preserving selected Codex desktop sessions in encrypted, user-owned Google Drive storage—with exact restore checks.
How it worksDesign principles
User controlled
Backups go to storage you own and can revoke, inspect, or remove.
Recovery tested
A backup is not treated as complete until an isolated restore is verified.
